Caleb and sergio stacked boxes on a shelf. caleb lifted 14 boxes and sergio lifted 12 boxes. the boxes that sergio lifted each weighed 10 lb more than the boxes caleb lifted. let c represent the weight of each box caleb lifted. which expression represents the total number of pounds sergio lifted?

Step-by-step explanation:

1. You have the following information given in the problem above:

- Sergio lifted a total of 12 boxes.

- The weight of each box that Sergio lifted was 10 pounds more than the boxes Caleb lifted ().

2. Therefore, based on the information shown above, you can express the total number of pounds Sergio lifted, as following:

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
