Answer:

a=-3

Step-by-step explanation:

-2a-9=6a+15

Add 9 to both sides:

-2a-9+9=6a+15+9

-2a=6a+24

Subtract 6a from both sides:

-2a-6a=6a+24-6a

-8a=24

Divide both sides by -8:

\frac{-8a}{-8}=\frac{24}{-8}

a=-3

Jose asks his friends to guess the higher of two grades he received on his math tests. He gives them two hints. The difference o
tatyana61 [14]

Answer : 96

x – y = 16 --------> equation 1

1/8 x + 1/2 y = 52

x is the higher grade and y is the lower grade

We solve the first equation for y

x - y = 16

-y = 16 -x ( divide each term by -1)

y = -16 + x

Now substitute y in second equation

1/8 x + 1/2 ( -16 + x ) = 52

1/8x - 8 + 1/2 x = 52

1/8x + 1/2x - 8 = 52

Take common denominator to combine fractions

1/8x + 4/8x -8 = 52

5/8x - 8 = 52

Add 8 on both sides

5/8x = 60

Multiply both sides by 8/5

x = 96

We know x is the higher grade

96 is the higher grade of Jose’s two tests.
