Answer:
Candace has $57.5 and Amar has $37.5.
Step-by-step explanation:
x+(x+20)=z
x+20=y
x+y=z
--------------
2x+20=95
2x=95-20
2x=75
x=75/2
x=37.5
37.5+20=y=57.5
Answer:
21 weeks.
Step-by-step explanation:
To start, you have to get the pounds lost per week.
12/3=4
4 pounds lost per week.
Next, find out how many weeks it takes by solving this equation,
4x=84
Divide 84/4=21
Therefore, it took 21 weeks to lose 84 pounds.
So n will be the unknown, and the expression is:
6n = 24
from where we can find the number n:
n = 24/6
n = 4
