Jan mixed 2 pints of blue paint with 5 pints of red paint to make purple paint. he wrote the equation b= ( )r to represent the proportional relationship. what number should go in the box. explain how you know plzz i will give you 100 points

so here

ratio of mixture is actually ratio of number of pints

so

blue pints/ red pints = b/r =2/5

so

b = (2/5) r

b = (0.4) r

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
