Lisa mixes 3 units of red paint with 8 units of white paint to get pink. How many units of red paint should she mix with 12 units of white paint to get the same pink shade

Lisa should mix 4.5 units of red paint with 12 u its of white paint.

Step-by-step explanation:

Lisa mixes 3 units of red paint with 8 units of white paint to get pink. This means that the ratio of red paint to white paint is 3/8.

Let x represent the number of units of red paint that she should mix with 12 units of white paint to get the same pink shade. Therefore

3/8 = x/12

Cross multiplying, it becomes

8 × x = 3 × 12

8x = 36

x = 36/8 = 4.5

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
