The equation for the first part would be 4.50p+40=112.
This is because he earns 40 dollars in wages which doesn't change but the number of shoes he commissions, which would be 4.50 per pair. varies based on how many he commissions.

The answer to your second part would be 16.
To find the number, you subtract 40 from each side which gets you 4.50 = 72. From there you just divide which gets you 16.

Another easy way to do it would just be substituting until you find the right number like on a calculator but if you don't have a calculator on hand (let's say for a test), than the first way would be more effective.

Complete the steps to simplify (y^4/3•y^2/3)^-1/2. Apply the product of powers property to the expression inside the parentheses
MrRissso [65]

Option A

\left(y^{\frac{4}{3}} \cdot y^{\frac{2}{3}}\right)^{\frac{-1}{2}} = \left(y^{2}\right)^{\frac{-1}{2}}

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

\left(y^{\frac{4}{3}} \cdot y^{\frac{2}{3}}\right)^{\frac{-1}{2}}

<em><u>Product of powers property:</u></em>

The product of powers property tells us that when you multiply powers with the same base you just have to add the exponents

Which is represented as,

a^m.a^n = a^{m+n}

<em><u>Therefore, the given expression becomes,</u></em>

\left(y^{\frac{4}{3}+\frac{2}{3}}\right)^{\frac{-1}{2}}

Now add the exponents, we get

\left(y^{\frac{4+2}{3}}\right)^{\frac{-1}{2}}

Simplify the above expression

\left(y^{\frac{6}{3}}\right)^{\frac{-1}{2}}

Simplify the exponent of y, we get

\left(y^{2}\right)^{\frac{-1}{2}}

Thus Option A is correct

Jimmy and his family took a three-day trip. They drove 198 miles on the first day, 150 miles on the second day, and 210 miles on
MAVERICK [17]
The average driving speed would be 62 because you add 198, 150, and 210 and divide the total by 9.

Hope this helped :)
