Answer:

x=9

Step-by-step explanation:

5( x + 7) - 3 ( x - 4) = 7x + 2

Distribute

5x+35 - 3x +12 = 7x +2

2x +47 = 7x+2

Subtract 2x from each side

2x+47-2x =7x -2x+2

47 = 5x+2

Subtract 2 from each side

47-2= 5x+2-2

45= 5x

Divide by 5

45/5 =5x/5

9 =x

Answer:

x = 9

Step-by-step explanation:

<u>→Distribute the 5 to (x + 7), Distribute the -3 to (x - 4):</u>

5(x + 7) - 3(x - 4) = 7x + 2

5x + 35 - 3x + 12 = 7x + 2

<u>→Add like terms:</u>

2x + 47 = 7x + 2

<u>→Subtract 2x from both sides:</u>

47 = 5x + 2

<u>→Subtract 2 from both sides:</u>

45 = 5x

<u>→Divide both sides by 5:</u>

9 = x

EleoNora [17]

The ratio of 1:3 is equivalent to 12/36. The ratio 3 / 4 is not equivalent to 12/36.

Given that,
The ratio__ is equivalent to 12/36. The ratio__is not equivalent to 12/36.
Blank statement to be filled from the options.

<h3>What is the Ratio?</h3>

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Here,
12 / 36 = 1 / 3
and
12 / 36 ≠ 3 / 4

Thus,  the ratio of 1:3 is equivalent to 12/36. The ratio 3 / 4 is not equivalent to 12/36.

vodomira [7]

Answer:

3.14

Step-by-step explanation:

First find the circumference of the circle:

2\pi r = Circumference.

2 * \pi * 6 = 12\pi

Find the ratio of the angle in relation to the entire circle:

30^o is what we have. So:

\frac{30^o}{360^o} = \frac{1}{12}

Use the ratio and multiply the circumference to find the length:

12\pi * \frac{1}{12} = \pi

Round answer to the hundredth:

\pi = 3.14
