1.Solve the system using elimination. 4x + 4y = 12
7x - 4y = 10

2.Solve the system using any method
x + y = 1.7
4x + y = 0.8

3.On a team, 8 girls and 6 boys scored a total of 64 points. The difference between the number of points scored by the 8 girls and the number of points scored by the 6 boys is 16. Each girl scored the same number of points and each boy scored the same number of points. Find the number of points scored by each girl and each boy.

4.Sovle the system of equation by the addition method
{2x = 2y + 5
{-6x + 3y = -30

5.Sovle the system by either the addition method or the substitution method
{ 4y = 5x + 20
{3x - 4y = -20

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
