Greg and Josh want to go whitewater rafting in 3 weeks. Josh is able to save the $480 he needs to go on the trip by saving the p
Marat540 [252]

Answer:

Josh makes $36 more per hour than Greg.

Step-by-step explanation:

First, you need to determine the amount Josh earns per hour as you know that it takes him 5 hours of work to save $480:

5x=480

Now, you can solve for x:

x=480/5

x=96

Then, you need to determine the amount Greg earns per hour as you know that it takes him 8 hours of work to save $480:

8y=480

Now, you can solve for y:

y=480/8

y=60

96-60=36

According to this, the answer is that Josh makes $36 more per hour than Greg.

Law of radicals
andrey2020 [161]

Answer:

1)  \sqrt{x^7}=x^{\frac{7}{2}

2)  \sqrt[3]{y^5}=y^{\frac{5}{3}

3) \sqrt[5]{a^{12}}=a^{\frac{12}{5} }

4) \sqrt[4]{z^{9}}=z^\frac{9}{4}

Step-by-step explanation:

1) \sqrt{x^7}

We know that \sqrt{x}=x^{\frac{1}{2}

So, \sqrt{x^7}=x^{\frac{7}{2}

2) \sqrt[3]{y^5}

We know that \sqrt[3]{x}=x^{\frac{1}{3}

So, \sqrt[3]{y^5}=y^{\frac{5}{3}

3) \sqrt[5]{a^{12}}

We know that \sqrt[5]{x}=x^{\frac{1}{5}

So, \sqrt[5]{a^{12}}=a^{\frac{12}{5} }

4) \sqrt[4]{z^{9}}

We know that \sqrt[4]{x}=x^{\frac{1}{4}

So, \sqrt[4]{z^{9}}=z^\frac{9}{4}

I picked up 15 shells and my brother picked up 3 more shells than I did. How many shells did my brother pick up?
Artist 52 [7]
Let you = y
Let your brother = b

y = 15
b = y + 3

Plug in 15 for y

b = 15 + 3
b = 18

Your brother picked up 18 shells.

Hope this helps
