e-lub [12.9K]

Answer:

Cost =$3

Amount = 8 gallons and 17 gallons

Step-by-step explanation:

Given

24 + 51

Required

3(8 + 17)

The above can't be factored any further.

Since the cost of gas for both individuals is the same, we can conclude the following.

Cost = $3

This is so because it applies to both numbers in brackets

Amount of Gas = 8 gallons and 17 gallons respectively by both individuals

Answer:

2 and 1/4 or 2.25. Both numbers are the same.

Step-by-step explanation:

Hi,

Please see the picture I had to upload in order for this question to be complete. Please also note that Kara has 3 buttons in the 3/4 length. You have to sum up only those in that length and ignore the ones in different lengths.

It is a very simple multiplication, and there are 2 ways to do so. You can use either fractions or integer numbers. See the 2 options below:

3/4 (fractions) = .75 (integer numbers)

Option one - 3 * 3/4 = 9/4 which is represented by 2 and 1/4.

Option two - 3 * .75 = 2.25

Have a good one!
