Given that R = 3x + 9y

Bingel [31]

Answer:

Step-by-step explanation:

R = 3x + 9y

They told us that R = 7, y = 6

So you can rewrite the equation as:

R = 3x + 9y

7 = 3x + 9(6)

7 = 3x + 54

Subtract 54 from both sides.

7 - 54 = 3x

-47 = 3x

To find x, you need to divide both sides by 3

3x = -47

x = -47/3

Please help! Israel added $80 to his savings. This added amount represents 1/8 of his total savings. If s represents the total s

Montano1993 [528]

Answer:

$s+80=\dfrac{1}{8}s$

Step-by-step explanation:

Let s represents the total Israel's savings.

Israel added $80 to his savings. Hence, he then had $(s+80).

This added amount represents $\frac{1}{8}$ of his total savings. $\frac{1}{8}$ of his total savings is

$\dfrac{1}{8}s$

Therefore,

$s+80=\dfrac{1}{8}s$
