Answer:

x = 5

Step-by-step explanation:

This equation can be rearranged in order to easily solve.

First, rearrange the equation by simply flipping it.

3x + 30 = 9x → 9x = 3x + 30

Then, you may solve for x.

9x = 3x + 30 subtract 3x from both sides of the equation

6x = 30 divide by 6 on both sides of the equation

x = 5

Answer:

100

Step-by-step explanation:

V (x) = 5x²+ 5x

x=4

We plug in the x value:

V (x) = 5(4)²+ 5(4)

Now we sovle the equation:

5(4)² + 5(4)

5(16) + 5(4)

80 + 20

= 100

Answer:

The Independent Variable is the variable or thing that depends on nothing, nothing can affect it, nor can it be changed by any other variables, in this case the Independent variable is the Fish tank, the fish tank depends on nothing, and will stay the same.

The Dependent Variable is the variable or thing that depends on one or more variables in the equation, it be changed by any other variables, in this case the dependent variable is the fish, the fish depend on the water in the tank.

Answer:

14 boys paid for the full year fee and 4 boys paid for the partial year fee

Step-by-step explanation:

Create a system of equations, where x is the number that paid for the $24 fee and y is the number that paid for the $16 fee:

24x + 16y = 400

x = y + 10

Solve by substitution by plugging in y + 10 as x:

24x + 16y = 400

24(y + 10) + 16y = 400

Solve for y:

24y + 240 + 16y = 400

40y + 240 = 400

40y = 160

y = 4

Then, plug in 4 as y to find x:

x = y + 10

x = 4 + 10

x = 14

So, 14 boys paid for the full year fee and 4 boys paid for the partial year fee.

Answer:

-5

Step-by-step explanation:

Coordinate of A = -7

Coordinate if B = 5

Distance of AB = |-7 - 5| = |-12| = 12

We are asked to find the coordinate of the point that would be ⅙ from the A to B, which is ⅙ of AB.

Let's find what ⅙ of AB is.

AB = 12

Therefore, ⅙ of AB = ⅙*12 = 2.

From point A (-7), we move 2 points towards B which will give us ⅙ from A to B.

The coordinate = -7 + 2 = -5

-5 is the coordinate of the point with a fraction distance of ⅙ from A to B.

Step-by-step explanation:

Hey, there!

As it is a Right angled triangle, taking reference angle as angle B.

hypotenuse (h)= AB

perpendicular (p)= 12

base (b)= 24.

Now, let's look which ratio can be used here as p and b are given. Let's use tan ratio here.( as tan = p/b)

[tex] \tan(theta) = \frac{p}{b} [/tex]

[tex]tan(theta) = \frac{12}{24} [/tex]

[tex] \tan(theta) = \frac{1}{2} [/tex]

or, tan theta = (0.5)

Shifting tan to right side making it inverse.

or, theta = tan inverse (0.5)

Therefore, theta = 26.56° or 27° { by rounding off 26.56° we get 27°}.

Answer:

SU = 36

Step-by-step explanation:

T is the mid point so the distance of ST and TU is the same. Since ST and TU are the same, 7x + 4 = 10x - 2.

Solve for x

7x + 4 = 10x - 2

7x - 10x = - 2 - 4

-3x = -6

x = 2.

Find SU

SU = ST + TU

= (7x + 4) + (10x - 2)

substitute the value for x into the equation (x=2)

[7(2) + 4] + [10(2) - 2] = 36

I hope this helps :)

Answer:

-2n+6

Step-by-step explanation:

-2n+6

Hope this helps ;) ❤❤❤

Answer:

-2n + 6

Step-by-step explanation:

Combine like terms (terms with the same amount of variables).

Note the laws of signs:

Two additions signs: If there are two addition signs directly next to each other (which will not be shown very much), it means to add.

One addition sign & One negative sign: If there is one of each signs directly next to each other (as shown here), you must default it to negative and subtract.

Two negative signs: If there are two negative signs directly next to each other, you must default it to positive and add.

First, change the expression to signify how you should combine the terms:

5n + 6 + (-7n) = 5n - 7n + 6

Combine like terms:

(5n - 7n) + 6

-2n + 6

-2n + 6 is your answer.

Answer:

[tex]\sqrt{20}[/tex]

Step-by-step explanation:

To find the Apothem of a shape, we need to find how long the distance is from a vertex to the center of the shape.

We can see that they've already showed us how to do it: We need to find the length of the hypotenuse of the red triangle.

To do this, we can use the Pythagorean Theorem, which states that [tex]a^2 + b^2 = c^2[/tex].

We know that a is going to be half of 4, which is 2. We also know that b is going to be 4, so we can substitute inside the equation.

[tex]2^2 + 4^2 = c^2\\\\4 + 16 = c^2\\\\20=c^2\\\\c=\sqrt{20}[/tex]

Answer:

C

1/7 is greater than 1/8 so 1/7 must go after it. but negative is always less then positive so the correct order is

-1/8, -1/7, 1/8, 1/7

The numbers arranged in increasing order is

-1/8, -1/7, 1/8, 1/7

There are 4 values given:

1/7, 1/8, - 1/7, - 1/8

Negative figures are generally lesser than positive figures

1/7 is greater than 1/8

In negative values, the greater number becomes the smaller number

Therefore,

-1/8 is the the smaller number

Arrangements in increasing order =

-1/8, -1/7, 1/8, 1/7
