John went on a bike ride to the store 4 miles away. If it took John 3/10 of an hour to get there and 1/2 of an hour to get back,
stiv31 [10]

The round trip was 8 miles ( 4 + 4 = 8)

The total time for the trip is 3/10 + 1/2

Rewrite 1/2 as 5/10

Now add 3/10 + 5/10 = 8/10 = 4/5 hour for the 8 mile trip.

Now to find miles per hour, divide total miles by total time:

8 miles / 4/5 hour

When you divide by a fraction flip the fraction over and multiply:

8 x 5/4 = 40/4 = 10

The average rate was 10 miles per hour.

Andreas93 [3]

4(2x-5)+7(x+2)

bracket means multiplying

do 4(2x+5) first

4*2x=8x

4*-5=-20

7*x=7x

7*2=14

8x-20+7x+14

do the x first

8x+7x=15x

-20+14=-6

I need help with this math problem
boyakko [2]
Consider the right triangle HBF. The Pythagorean theorem tells you ...
   HF² = HB² + BF²

The lengths HB and BF can be determined by counting grid squares, or by subtracting coordinates. Here, it is fairly convenient to count grid squares. When we do that, we find ...
   HB = 2
   BF = 5
Using these values in the equation above, we get
   HF² = 2² + 5²
   HF² = 4 + 25 = 29
Taking the square root gives the length HF.
   HF = √29
