The answer is 6 per team with 2 left over, as (6 x 3) + 2 = 20

I thought of the largest amount that could be multiplied by 3, but the product would be less or equal to 20, that's how I got 6.

Then to find the left over remaining balls that are given out I subtracted 20-18 = 2.

You like the size of your MP3 player. The width is 4 centimeters. The length is 7 centimeters. The height measures 1 centimeter.

Basile [38]

Answer:

78mm^2

Step-by-step explanation:

based on the information given, we can tell that the shape of the MP3 player is a rectangle. The formula for the surface area of a rectangle is SA=2WL+2LH+2HW

SA = Surface Area

W = Width

L = Length

H = Height

SA = 2(4)(7) + 2(7)(1) + 2(1)(4)

= 2(28) + 2(7) + 2(4)

= 56 + 14 + 8

= 78

A sports magazine prints 12 issues per year, and a technology magazine prints 10 issues per year. The total number of pages in a

Evgesh-ka [11]

Answer:

$s=t-18...(1)$

$12*s=10*t+32...(2)$

Step-by-step explanation:

Let s be the number of pages in each issue of the sports magazine, and t be the number of pages in each issue of the technology magazine.

We have been given that Each issue of the sports magazine has 18 fewer pages than each issue of the technology magazine. We can represent this information in an equation as:

$s=t-18...(1)$

We are also given that sports magazine prints 12 issues per year, so the total number of pages in all the issues of sports magazine will be 12*s.

We are given that a technology magazine prints 10 issues per year, so the total number of pages in all the issues of technology magazine will be 10*s.

Further, the total number of pages in all the issues of the sports magazine for one year is 32 more than the total number of pages in all the issues of the technology magazine for one year.

We can represent this information in an equation as:

$12*s=10*t+32...(2)$

Therefore, our desired system of equations will be:

$s=t-18...(1)$

$12*s=10*t+32...(2)$
