Alejandra paints faces at kids’ birthday parties to earn extra money. the equation
m = 2.50f + 12 represents the relationship between the money she makes, m, and the number of faces she paints, f.
• alejandra wants to buy a new pair of uggs that cost $119.50. how many faces does she need to paint

Step-by-step explanation:

m = 2.50f + 12m represents the total money she makes

and if she wants to buy the uggs, she needs to make 119.50so sub 119.50 in for m and solve for f

119.50 = 2.50f + 12

119.50 - 12 = 2.50f

107.50 = 2.50f

107.50 / 2.50 = f

43 = f <=== she needs to paint 43 faces to get enough money to buy her uggs

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

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.
