Isabel drove 864 miles in 12 hours.<br> At the same rate, how many miles would she drive in 7 hours?
lyudmila [28]

Answer:

504 miles

Step-by-step explanation:

Make a proportion

\frac{864}{12} = \frac{x}{7}

7/12 is 0.5833, so multiply 864 by that to find the number of miles

864(0.5833) = 504

Answer:

11/20

Step-by-step explanation:

Finding the common denominator, which is 20, we convert 1/5 into 4/20 and 1/4 into 5/20. Adding those up, the remainder when subtracted from 1, the total, is 11/20.

-8x-27=-7\left(1+2x\right)+2x
Darina [25.2K]

Answer:

x=5

Step-by-step explanation:

-8x-27=-7\left(1+2x\right)+2x

Expand:

-8x-27=-7\times 1-7\times 2x+2x

-8x-27=-7-12x

Add 27 to both sides:

-8x-27+27=-7-12x+27

-8x=-12x+20

Add 12x to both sides:

-8x+12x=-12x+20+12x

4x=20

Divide both sides by 4:

\frac{4x}{4}=\frac{20}{4}

x=5
