Mr. Anderson drove 168 miles in 3 1/2 hours. He then drove the next 2 1/4 hours at a rate of 5 miles per hour faster than the fi
BlackZzzverrR [31]
First we need to know how many miles per hour they drove the first time. This would be found by division. 168/3.5=48
Then we need to add 5 miles per hour for the average.48+5= 53
Next we need to multiply 2 1/4 by the new miles per hour 53*2.25=119.25
After that we need to know how many miles they drove 119.25+168=287.25 miles.
Finally to get an improper fraction we need to change 287.25 miles to it.
We already have 1/4 for .25 so we multiply 287 by 4 and add it to the 1/4 we already have and it makes it out to be 1149/4

Hope this helps!

Three consecutive integers have a sum of 42. Find the integers.
faltersainse [42]

Answer:

13, 14, 15

Step-by-step explanation:

Three consecutive integers have a sum of 42 means which 3 numbers in a row add up to 42

We can call the lowest integer x,

the next integer x+1 (since our integers need to be even)

the third integer x+2

algebraic equation: 42 = x + (x+1) + (x+2).

Combine like terms on the right side,

42 = 3x + 3

Subtract 3 from each side

39 = 3x

Divide each side by 3

x=13, which is our lowest integer.

The next two integers we find with 13 + 1 =.14 and 13 + 2 = 15

13 + 14 + 15 = 42.
