Answer:
$12
Step-by-step explanation:
Hi there!
What we know:
- Brooklyn bought 8 bags of dog food
- Brooklyn also used a $5 coupon
- The total was $91
Therefore, 8 × (cost of 1 bag) - 5 = 91
Form an equation with x as the cost of 1 bag of dog food:
8 × (cost of 1 bag) - 5 = 91
Add 5 to both sides
Divide both sides by 8
Therefore, 1 bag of dog food costs $12.
I hope this helps!
Answer:
3x + 12
Step-by-step explanation:
I got this answer because since 8x and -5x are like terms, you are able to subtract them from each other. 8x-5x is 3x. Since you cant add 12 to 5x because they aren't like terms, you leave the expression as it is right now. Finally, your answer is 3x + 12.
Hope I helped! Have a good day.
Answer:
x = -3
y = -14
Step-by-step explanation:
4 + 6x = -2 + 4x
6x - 4x = -2 - 4
2x = -6
x = -3
y = -2 + 4(-3)
y = -14
y = 4 + 6(-3)
y = -14
