Answer:

y = (5/3)x - 4

Step-by-step explanation:

We put the equation in the form y = mx + b.

So,

9y - 15x = -36 implies that

3y - 5x = -12, dividing through by 4, and continuing we have that,

3y = 5x - 12

3y/3 = 5x/3 - 12/3, dividing through by 3, and continuing we have that,

y = (5/3)x - 4

The circumference of circle x in which a = 49pi in squared

zzz [600]

Answer:

C = 14 pi inches

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

49 pi = pi r^2

Divide each side by pi

49 pi/pi = pi /pi r^2

49 = r^2

Take the square root of each side

7 = r

The circumference is given by

C = 2 * pi *r

C = 2 * pi *7

C = 14 pi inches

I have no idea how to slove this 5x-5 =2×+97

galina1969 [7]

Answer: x=34

Step-by-step explanation:

1. You subtract 2x from 5x on the other side to get rid of the 2x leaving you with 3x.

2. Then you add 5 to 97 to get rid of the -5, giving you 102 on the opposite side.

3. divide 102 by 3x giving you 34.

5x-5=2x+97

-2x -2x

3x-5=97 <u><em>X=102</em></u>

+5 +5

3x=102

x/3 102/3
