Answer:
Step-by-step explanation:
6x+3x= -2
9x= -2
x= -2/9
You will subtract 12 from 260 and get 248 then you will divide 248 by 8 and get 31 dollars spent per book.
Answer:
50 combos
Step-by-step explanation:
Put it into an equation first in order to find x.
2x + 250 = 7x
Subtract 2x from both sides.
250 = 5x
Then divide both sides by 5.
x = 50
Therefore you need 50 combo meals in order to make the amount made equal to the amount paid.
<u>You can check your work by plugging in the number to both.</u>
$250 plus the $2 times 50 combo meals.
250 + 2(50) = 350
$7 times 50 combo meals
7 x 300 = 350
