Answer:
for 6: -2x+30
I dont know for # 8
Step-by-step explanation:
to distribute, you have to multiply -3 by x and -10.
-3(x) - -3(10) + x =
-3x + 30 + x:
then you have to add common terms
-3x + x = -2x
then replace that in your equation to get:
-2x +30
Answer:
Step-by-step explanation:
<u>Given the equation: </u>
- E - weekly total, g- number of hours at gas station, t- number of hours at toy store.
<u>Substitute given values into equation and solve for the missing one:</u>
- 219.75 = 9.25g + 10.5*13
- 219.75 = 9.25g + 136.5
- 9.25g = 219.75 - 136.5
- 9.25g = 83.25
- g = 83.25/9.25
- g = 9
