Answer:
m=25w+80
Step-by-step explanation:
m=money
w=weeks
280-130=150
150/6=25 this is how much she earns per week
25*2=50 this is how much she earned in two weeks
130-50=80 this is how much she had before she worked
m=25w+80
plug in to check:
(25*2)+80=130
(25*8)+80=280
Answer:4
Step-by-step explanation: 144/36=4
The choices are equivalent to the expression correct choices are A, C, and D.
The given expression is
x^3 /5
<h3>
What is the expression?</h3>
The expression consists of numbers and arithmetic operators. It does not contain equality or inequality symbols.
<h3>What is the power rule?</h3>
![a^{\frac{m}{n} =\sqrt[n]{a^m}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%20%3D%5Csqrt%5Bn%5D%7Ba%5Em%7D)
Therefore the above power rule implies that,
![x^{(\frac{3}{5}) }=\sqrt[5]{x^3}](https://tex.z-dn.net/?f=x%5E%7B%28%5Cfrac%7B3%7D%7B5%7D%29%20%7D%3D%5Csqrt%5B5%5D%7Bx%5E3%7D)
Also, we have the power rule


or it can be written as
![x^{\frac{3}{5} =(\sqrt[5]{x})^3](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B3%7D%7B5%7D%20%3D%28%5Csqrt%5B5%5D%7Bx%7D%29%5E3)
The correct choices are A, C, D.
