Scarlett is playing a video game. she spends 90 minerals to create 18 workers. each worker costs the same number of minerals. write an equation to describe the relationship between m, the amount of minerals, and w, the number of workers.

Step-by-step explanation:

Let

m-----> the amount of minerals

w-----> the number of workers

we know that

so

-----> the relationship represent a proportional variation

m=50w

Step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

answer:

a=9
