Answer:-4

Step-by-step explanation:

-4 x -7 = 28

28-9=19

Answer:

x=-4

Step-by-step explanation:

We are given the equation:

-7x-9= 19

We want to solve for x. Therefore, we must isolate x on one side of the equation.

9 is being subtracted. The inverse of subtraction is addition. Add 9 to both sides of the equation.

-7x-9+9= 19+9

-7x= 28

x is being multiplied by -7. The inverse of multiplication is division. Divide -7 on both sides.

-7x/-7=28/-7

x= 28/-7

x= -4

Let’s check our solution. Plug -4 in for x and solve.

-7x-9=19

-7(-4)-9=19

28-9=19

19=19

This checks out, so we know our solution is correct.

The solution to the equation -7x-9=19 is x= -4

Answer:

x < -17

Step-by-step explanation:

-3-7x - 41 - 7>68

Combine like terms

-7x-51>68

Add 51 to each side

-7x-51+51>68+51

-7x > 119

Divide each side by -7, remembering to flip the inequality

-7x/-7 < 119/-7

x < -17

Full Question:

The student council needs posters for the Winter Carnival. The print shop charges $15 for each print job. Each poster will cost an additional  $1.35.

Which equation shows the  relationship between the number of posters, n, and the total cost, c, in dollars?

Answer:

[tex]C = 15 + 1.35n[/tex]

Step-by-step explanation:

Given

[tex]Base\ Charge = \$15[/tex]

[tex]Cost\ per\ print = \$1.35[/tex]

Required

Determine an equation to calculate the total cost

First, we need to determine the cost of n posters;

If 1 poster costs $1.35, then

[tex]n\ posters = n * 1.35[/tex]

[tex]n\ posters = 1.35n[/tex]

Next, add the cost of n posters to the base charge. This gives total cost (C)

[tex]C = Base\ Charge + n\ posters[/tex]

[tex]C = 15 + 1.35n[/tex]

Answer:  

I Did The Test And The Correct Answer is that c will equal to 1.35n + 15

It Is 1.35n + 15

Answer:

100 + x

Step-by-step explanation:

If Peter has an initial 100$, and his mom gives him an additional x$, then we can simply write the total amount in an expression using addition as such:

100 + x

So Peter now has 100 + x amount of dollars.

Cheers.

Answer:

[tex]\huge\boxed{\$(x+100)}[/tex]

Step-by-step explanation:

Peter has = $100

He has been given = $x more.

So, the expression becomes

=> $(100+x)

OR

=> $(x+100)

Answer:

Step-by-step explanation:

The area of a rectangle is expressed as A = Length * Width

Given the length of the rectangle = 4.4 cm

Width of the rectangle = 3.1 cm

Area of the triangle = 4.4 cm * 3.1 cm

Area of the triangle =13.64cm²

The full precision answer is 13.64cm²

Rounding the value up to the nearest cm² will give 14cm². Note that the value is rounded up to 14cm² because the first value (6) after the decimal point is greater than 4, hence 13 will be approximated to 14.

Answer:

[tex]x\approx49.3266\textdegree[/tex]

Step-by-step explanation:

So we want to find Angle x.

Note that we already know the side length of the side opposite to Angle x.

We also know that the hypotenuse is 56.3.

Therefore, we can use the sine function. Recall that:

[tex]\sin(x)=\frac{\text{opposite}}{\text{hypotenuse}}[/tex]

The opposite side is 42.7. The hypotenuse is 56.3. Substitute:

[tex]\sin(x)=\frac{42.7}{56.3}[/tex]

Take the inverse sine of both sides.

[tex]\sin^{-1}(\sin(x))=\sin^{-1}(\frac{42.7}{56.3})[/tex]

The left side cancels:

[tex]x=\sin^{-1}(\frac{42.7}{56.3})[/tex]

Use a calculator. Thus:

[tex]x\approx49.3266\textdegree[/tex]

And that's our answer :)

Answer:

[tex]\Huge \boxed{\mathrm{49.33 \° }}[/tex]

[tex]\rule[225]{225}{2}[/tex]

Step-by-step explanation:

The triangle is a right triangle.

We can use trig functions to solve for the missing angle.

[tex]\displaystyle \mathrm{sin \theta =\frac{opposite}{hypotenuse} }[/tex]

The opposite side to angle x is 42.7.

The hypotenuse of the right triangle is 56.3.

[tex]\displaystyle \mathrm{sin} (x)=\frac{42.7}{56.3}[/tex]

Taking inverse sin of both sides.

[tex]\displaystyle x=\mathrm{sin^{-1}}( \frac{42.7}{56.3})[/tex]

[tex]x= 49.3265955[/tex]

The missing angle measures approximately 49.33°.

Answer: E. 99

Step-by-step explanation:

A composite number has more than two factors which means not only including 1 and itself, but at least one other.

factor of 29: 1, 29

factor of 41: 1, 41

factor of 71: 1, 71

factor of 79: 1, 79

factor of 99: 1, 3, 9, 11, 33, 99

Clearly 99 has more than two factors.

Answer: OPTION B

Step-by-step explanation:

Angle 25° is in the interior of two lines so we are actually finding the alternative interior angles.

Alternate angles are angles that on opposite sides that locate on opposite relative sides of the other lines.

The only three labeled angle that are interior. Angle 25°, Angle 2, and Angle 3.

Angle 25° and Angle 3 are on opposite sides, but they are on the same relative side of the other lines, which does not fit the alternate angle definition.

Angle 25° and Angle 2 are on opposite sides and on the opposite relative side of the other lines, so Angle 2 is the alternate to Angle 25°

Hope this helps!! :)

Answer:

[tex]Area = \frac{3}{16} m^2[/tex]

Step-by-step explanation:

Given

Shape: Rectangle

[tex]Length = \frac{1}{2}\ m[/tex]

[tex]Width = \frac{3}{8}\ m[/tex]

Required

Determine the area of the rectangle;

Area is calculated as thus;

[tex]Area = Length * Width[/tex]

Substitute values for Length and Width

[tex]Area = \frac{1}{2} * \frac{3}{8}[/tex]

[tex]Area = \frac{1 * 3}{2 * 8}[/tex]

[tex]Area = \frac{3}{16}[/tex]

Hence, the area of the rectangle is [tex]\frac{3}{16}m^2[/tex]

Answer:

15

Step-by-step explanation:

lets make an equation and solve it (its easier)

130=8x+10

130-10=8x

120=8x

x=120/8=15 hours

For the integral

[tex]I=\displaystyle\int_1^3\frac{\mathrm dx}{x\sqrt{1-(\log x)^2}}[/tex]

(assuming [tex]\log x[/tex] is the natural logarithm with base [tex]e[/tex]) substitute [tex]u=\log x[/tex] and [tex]\mathrm du=\frac{\mathrm dx}x[/tex]. Then the integral is equivalent to

[tex]I=\displaystyle\int_{\log1}^{\log e}\frac{\mathrm du}{\sqrt{1-u^2}}=\int_0^1\frac{\mathrm du}{\sqrt{1-u^2}}[/tex]

Next, substitute [tex]u=\sin t[/tex] and [tex]\mathrm du=\cos t\,\mathrm dt[/tex]:

[tex]I=\displaystyle\int_{\sin^{-1}0}^{\sin^{-1}1}\frac{\cos t}{\sqrt{1-\sin^2t}}\,\mathrm dt=\int_0^{\frac\pi2}\frac{\cos t}{\sqrt{\cos^2t}}\,\mathrm dt[/tex]

We have [tex]\sqrt{x^2}=|x|[/tex] for all [tex]x[/tex], but in the given integration interval, [tex]\cos t\ge0[/tex], so

[tex]I=\displaystyle\int_0^{\frac\pi2}\frac{\cos t}{\cos t}\,\mathrm dt=\int_0^{\frac\pi2}\mathrm dt=\boxed{\dfrac\pi2}[/tex]

(Of course, with a little foresight, you could have immediately combined the two substitutions and started off with letting [tex]\sin u=\log x[/tex].)

For the number system diagram, from smallest box to larges, it would be natural numbers, whole numbers, and integers, rational numbers, then real numbers. And irrational numbers off to the side, but considering you only have 3 boxes then put the first 3 I mentioned.

It is definetly possible for a number to be both whole and an integer. As long as it's not a fraction, decimal, or negative value.

The image showing the dimensions of the truck in question is missing, so i have attached it.

Answer:

Max amount of cargo that can fit in new truck = 756.39 cu.ft

Step-by-step explanation:

From the diagram attached, we can see that the delivery truck is in the form of a cuboid.

So let's say we extend the perpendicular line from the start of the extra ledge that sticks out to the top of the truck.

This will mean that we have now divided the big truck into 2 different cuboids which we will call C1 and C2.

For C2, We can see that the height is 6' 6", width is 7' 8", length is 14' 3".

Converting the dimensions to inches, we know that, 1 ft = 12 inches

Thus;

6' 6" = (6 × 12) + 6 = 78"

7' 8" = (7 × 12) + 6 = 90"

14' 3" = (14 × 12) + 6 = 174"

Thus, volume of cuboid = Length x width x height

Thus, volume of cuboid 1 is;

V1 = 78 × 90 × 174 = 1221480 cu.inches

Looking at the smaller cuboid C1, the height is 2' 7" and the width remains 7' 8".

To get the length, we have; length = 16' 9" - 14' 3" = 2' 6"

So Converting these to inches gives;

7' 8" = (7 × 12) + 8 = 92"

2' 7" = (2 × 12) + 7 = 31"

2' 6" = (2 × 12) + 6 = 30"

Volume of cuboid 2 is;

V2 = 92 × 31 × 30 = 85560 cu.inches

Total volume = V1 + V2 = 1221480 + 85560 = 1307040 cu.inches

Now, converting cu.inches to cu.ft, we know that;

1 cu.inches = 1/1728 cu.ft

Thus;

1307040 cu.inches = 1307040 × 1/1728 = 756.39 cu.ft

Answer:

47°

Step-by-step explanation:

Given that m<BOC = 6x + 29, m<AOB = 3x + 124, and m<AOC is a straight angle, therefore, m<AOC = 180°.

m<BOC +m<AOB = 180°

6x + 29 + 3x + 124 = 180

Solve for x

6x + 3x + 29 + 124 = 180

9x + 153 = 180

Subtract both sides by 153

9x = 180 - 153

9x = 27

Divide both sides by 9

x = 3

m<BOC = 6x + 29

Plug in the value of x

m<BOC = 6(3) + 29

m<BOC = 18 + 29 = 47°
