Simplify to create an equivalent expression. 8-4(-x+5)

Answer:

no solution

Step-by-step explanation:

3x - 4 = 3x - 10

Subtract 3x from each side

3x-3x - 4 = 3x-3x - 10

-4 = -10

This is never true so there is no solution

Answer:

Step-by-step explanation:

I think you might have copied down the problem incorrectly.

If you try and solve this problem by moving the variables onto one side and the constants onto the other, you get:

3x-4=3x-10

   +10    +10

3x+6=3x

-3x     -3x

6=0 (which is FALSE)

Hope this helps!

P.S. Please give me brainliest. Thanks :)

Answer:

  161.8 cm²

Step-by-step explanation:

The given formula works if you have both legs of the triangle. Using the given information, a better formula is ...

  A = (1/2)ab·sin(C) . . . . C is the angle between sides 'a' and 'b'

  A = (1/2)(27.6 cm)(30 cm)sin(23°) ≈ 161.8 cm²

Answer:

cross multiplication would be the quickest technique that works to visualize this set of questions..

if [tex]\frac{a}{b} = \frac{c}{d}[/tex]  then ad = bc

each item that does not have a denominator add a "1" as the denominator

so first item... [tex]\frac{sin(50)}{1} = \frac{x}{4}[/tex]  

[tex]\frac{4 * sin(50) }{1} = x[/tex]     x = [tex]4\sin \left(50^{\circ \:}\right)=3.06417\dots[/tex]

#b) [tex]3\tan \left(81^{\circ \:}\right)=18.94125[/tex]

#c) [tex]6\cos \left(33^{\circ \:}\right)=5.03202[/tex]

.

.

#g)[tex]7.1\tan \left(18.4^{\circ \:}\right)=2.36185[/tex]

Step-by-step explanation:

Answer:

First we extract the sin or the tan according to the question and multiply the number with the denominator and extract the x .

[tex] \sin(50) = \frac{x}{4} \\ 0.766 = \frac{x}{4} \\ x = 3.06[/tex]

[tex] \tan(81) = \frac{x}{3} \\ 6.31 = \frac{x}{3} \\ x = 18.93[/tex]

[tex] \cos(33) = \frac{x}{6} \\ 0.83 = \frac{x}{6} \\ x = 0.83 \times 6 \\ x = 4.98[/tex]

[tex] \cos(75 ) = \frac{x}{3.5} \\ 0.258 = \frac{x}{3.5} \\ x = 0.2588 \times 3.5 \\ x = 0.90[/tex]

[tex] \sin(24) = \frac{x}{4.2} \\ 0.406 = \frac{x}{4.2} \\ x = 0.406 \times 4.2 \\ x = 1.70 [/tex]

[tex] \tan(42) = \frac{x}{10} \\ 0.9 = \frac{x}{10} \\ x = 9[/tex]

[tex] \frac{x}{7.1} = \tan(18.4) \\ \frac{x}{7.1} = 0.33 \\ x = 0.33 \times 7.1 \\ x = 2.34[/tex]

[tex] \frac{x}{5.3} = \sin(64.7) \\ \frac{x}{5.3} = 0.9 \\ x = 4.77[/tex]

[tex] \frac{x}{12.6} = \cos(52.9) \\ \frac{x}{12.6} = 0.6 \\ x = 0.6 \times 12.6 \\ x = 7.56[/tex]

Answer:

Interest (I) = $18

Step-by-step explanation:

$15,000 by the end of grace period

$2,500 payment was made by the 3rd day

$15,000/$2500=6

6×3=18

I = PRT/100

I = (15,000 × 20% × 18 days)/100

I = {15,000 × 0.2 × (18/30)}/ 100

I= {15,000 × 0.2 × 0.6}/ 100}

I= {1800}/ 100}

I= {18}/ 1}

Interest (I) = $18

[tex]\boxed{\sf QS = 98}[/tex]

Step-by-step explanation:

QP = PS   [Diagonals are bisected(Divided into two equal parts) by the other diagonal of parallelogram]

So,

3x - 11 = 2x + 9

3x - 2x = 9 + 11

x = 20

Now,

QS = QP + PS

QS = 3x-11+2x+9

QS = 3(20)-11+2(20)+9

QS = 60 - 11 + 40 + 9

QS = 49 + 49

QS = 98

Answer:  QS=98

Step-by-step explanation: diagonals are bisected by the other diagonal parallelogram

Answer:

Linear f(x) = 2·x + 3

Quadratic f(x) = x² + 2·x - 3

Exponential f(x) = 3ˣ - 2

Step-by-step explanation:

1) Linear function

The general form of the linear equation is of the form, f(x) = y = m·x + c

Where;

m = The slope

c = y-intercept (Constant)

The linear function is therefore, f(x) = 2·x + 3

2) Quadratic function

The general form of the quadratic function is f(x) = a·x² + b·x + c

Where;

a, and b are the coefficients of x² and x respectively and c is the constant term

Therefore,  f(x) = x² + 2·x - 3, is a quadratic function, with a = 1, b = 2, and c = -3

3) Exponential function

The general form of the exponential function is f(x) = a·bˣ + k

Where;

a = The initial

b = The multiplier (growth or decay value)

k = vertical shift

Therefore, the function f(x) = 3ˣ - 2 is an exponential function with the initial = 1, b= 3, and k = -2

Answer:

Given volume= 32/3 π

Now, we know that volume of sphere = 4/3 π r³ according to the question.

[tex]\frac{4}{3} \pi r^{3} =\frac{32}{3} \pi[/tex]

Both π and 3 are canceled from both sides

Now,

[tex]4r^{2} =32[/tex]

Divide both sides by 4

[tex]r^{3} =\frac{32}{4} =8[/tex]

[tex]r^{3} =8[/tex]

[tex]r=(8)^{1/3} =(2\times 2 \times 2)^{1/3}[/tex]

[tex]r=(2^{3} )^{1/3} =2^{3\times1/3}[/tex]

[tex]r=2 \; cm[/tex]

Radius of sphere = 2 cm

Answer:

C. The amount of money that is raised

Step-by-step explanation:

in the equation, it is the amount of money that is raised because how much money is raised affects the amount of basketballs purchased.

In other words, if the amount of money is less, then there will be less basketballs purchased as a result. If the amount of money is more, then there will be more basketballs purchased as a result.

Answer:

C. the amount of money that is raised

Step-by-step explanation:

I always think of it like this:

independent: money they are raising

dependent: the amount of a certain item the money is being used on

Answer: you would have to divide $8.00/$2.75 and it would equal $2.90

Step-by-step explanation: This may help and if it does please thank me in the comments.

Answer:

Susan can purchase 2.9 kg of cherries.

Step-by-step explanation:

We need to take the amount of money available and divide by the cost of cherries per kilogram

$8.00 / $2.75  per kg

2.909090909 kg

Rounding to the nearest tenth, the solution is 2.9 kg

Susan can purchase 2.9 kg of cherries.

Step-by-step explanation:

The sequence above is a geometric sequence

For an nth term in a geometric sequence

[tex]A(n) = a ({r})^{n - 1} [/tex]

where n is the number of terms

r is the common ratio

a is the first term

From the question

a = - 16

To find the common ratio divide the previous term by the next term

That's

r = 24/-16 = -3/2 or -36/24 = - 3/2

Since we are finding the 8th term

n = 8

Substitute the values into the above formula

That's

We have the final answer as

Answer: [tex]243/5[/tex]

[tex]3^2/3(3^4)/5\\=9/3(3^4)/5\\=3(3^4)/5\\=(3)(81)/5\\=243/5[/tex]

The approximate length of the wire she attached to the pendant is 50.27

The radius is given as:

r = 8 cm

The approximate length of the wire she attached to the pendant is calculated as:

Length = 2pi r

Where

pi = 3.14

So, we have:

Length = 2 * 3.14 * 8

Evaluate the product

Length = 50.24

Hence, the approximate length of the wire she attached to the pendant is 50.27

Answer: The answer is 41.13.

Step-by-step explanation: I took the quiz and none of the other answers were correct.

Answer:

I will assume that ABCD is a parallelogram.

1. In a parallelogram, opposite sides are congruent so 3x = 18 which means x = 6.

2. The diagonals of a parallelogram bisect each other so BE is half of BD, therefore, BD = 7.5.

3. Consecutive angles of a parallelogram are supplementary so m∠ADC = 180° - 135° = 45°.

4. Consecutive angles of parallelograms are supplementary so 2x + 10 + 135 = 180 → 2x + 145 = 180 → 2x = 35 → x = 17.5°.

5.  Again, the diagonals bisect each other so -6 + 8v = 9v - 10 → v = 4.

6. DA || BC so ∠DAC and ∠ACB are (congruent) alternate interior angles, therefore, m∠DAC = 37°.

7. The area of a parallelogram is base * height; we know base = 18 and height = 21 u so area = 378 u.

Step-by-step explanation:

They are basically telling you to sum both equations. So,

(2x + 3y + 5) + (4x - 7y - 8)

= 2x + 4x + 3y - 7y + 5 - 8
