The answer to the proble is (c) the power property. Look at the picture above!
Answer:
divide each side by -5
Step-by-step explanation:
-5m = -40
divide each side by -5
-5m/-5 = -40/-5
m = 5
Answer: x=6

Answer:
The amount earned by Josie was $13.75 and the amount earned by her brother was $16.25
Step-by-step explanation:
Let
x ----> amount earned by Josie
y ---> amount earned by her brother
we know that
![\frac{x}{y}=\frac{5.50}{6.50}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D%3D%5Cfrac%7B5.50%7D%7B6.50%7D)
------> equation A
-----> equation B
Solve the system by substitution
Substitute equation A in equation B
![\frac{5.50}{6.50}y+y=30.00](https://tex.z-dn.net/?f=%5Cfrac%7B5.50%7D%7B6.50%7Dy%2By%3D30.00)
solve for y
![\frac{12.00}{6.50}y=30.00](https://tex.z-dn.net/?f=%5Cfrac%7B12.00%7D%7B6.50%7Dy%3D30.00)
![y=6.50(30.00)/12.00\\y=\$16.25](https://tex.z-dn.net/?f=y%3D6.50%2830.00%29%2F12.00%5C%5Cy%3D%5C%2416.25)
Find the value of x
![x=\frac{5.50}{6.50}(16.25)\\\\x=\$13.75](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B5.50%7D%7B6.50%7D%2816.25%29%5C%5C%5C%5Cx%3D%5C%2413.75)
therefore
The amount earned by Josie was $13.75 and the amount earned by her brother was $16.25
The quotient is the answer to a division problem.
