Dwayne is 4 years older than Sarah. In 7 years the sum of their ages will be 48 . How old is Dwayne now?
zalisa [80]

Answer: 37

Step-by-step explanation: If you start your math by taking 48 and subtracting 7 you will get 41, this question says it the sum of both ages will be 48 in 7 years so subtract those to get 48. After, you can subtract 4 from 41 since that is just the sum of both ages, you take 41 and minus 4, your answer is 37 (sorry if its wrong but I think its most likely going to be correct)

Gina rides her bike to work at an average of 10.4 miles per hour. She bikes 1.2 hours each day. How many miles does Gina ride ea
tatiyna
So 10.4mi = 1 hour

We need to find out how many miles 1.2 hours is.

1.) Well, the first step would be to multiply 1.2 on both sides of:
10.4mi = 1 hour

because that would make this number of miles is = to 1.2 hours which is wha we're looking for

1.2(10.4) mi = 1.2 hour

2.) Simplify
12.48 mi = 1.2 hour

3.) That means Gina rides 12.48 miles each day if she rides for 1.2 hours each day at a pace of 10.4 miles per hour :)
