Answer:
x * (rate of calories burned) = y
Step-by-step explanation:
The independent variable is the one that isn't being affected and therefore represents the time that Sabir walks and the number of calories he burns. Therefore, we can multiply x by the rate of calories burned to get y. The rate is not provided.
When x = 3 z = 57 57/3 = 19
19*8 = 152
So when X is equal to 8, Z is equal to 152.
So first, we need to find how much the tip is, which is 20% of $70. Or, 0.2*70, which equals $14. Micheal will pay $14 as tip.
Then to find total, we add 14 to 70, which is $84, which is the total bill.
Answer:
7x-5 = 9
x = 2
Step-by-step explanation:
Let x be the number
7x-5 = 9
Add 5 to each side
7x-5+5 = 9+5
Divide each side by 7
7x = 14
7x/7 = 14/7
x=2
