Answer:
0 —> 15
1 —> 13.75
2 —> 12.5
3 —> 11.25
Step-by-step explanation:
Every time she drives for 1 hour, the car uses up 1.25 gallons of gas. If she fills it up and doesn't drive anywhere, the car will still be full with 15 gallons. If she drives for an hour, you would need to subtract 1.25 from 15 which would equal 13.75.
Then if she drives another hour, then you would subtract another 1.25 from 13.75.
Or a quicker way to do it would be if you multiply the number of hours driven by the gallons used per hour then subtract it from the filled up tank.... So for example if she drove 3 hours —> 3•1.25=3.75 then 15-3.75=11.25
Distribute then multiply 6x to all the terms inside parenthesis remember order of operations starting from left to right when solving expressions so the when you distribute
is 30x3-6x2 the 3 and 2 after x represent x cubed and squared
Step-by-step explanation:
Square root is equivalent to 1/2 power:

Square root of 9 is 3. Multiply the exponents by 1/2 to get:

We can rewrite a cube root into a fractional index form.
So, we can rewrite:
![\sqrt[3]{m^{2}n^{5}} = (m^{2}n^{5})^{\frac{1}{3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bm%5E%7B2%7Dn%5E%7B5%7D%7D%20%3D%20%28m%5E%7B2%7Dn%5E%7B5%7D%29%5E%7B%5Cfrac%7B1%7D%7B3%7D)
