Pens are sold in packs of 3 for $5. pencils are sold in packs of 4 for $1. mr. james bought 9 pens and 4 pencils and also spent $3 on notepaper. which equation represents how much money, x, mr. james spent? (3 × $5) + $4 + $3 = x (9 × $5) + $1 + $3 = x (3 × $5) + $1 + $3 = x (3 ÷ $5) + $1 + $3 = x

C.(3 × $5) + $1 + $3 = x

Step-by-step explanation:

3x9=15($15 for pens)

$1 for pencils

$3 (for paper)

so (3 × $5) + $1 + $3 = x

don't know sorry bru

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
