A student bought 11 pencils and a pad of paper. • The pencils each cost the same amount.
• The pad of paper cost $4.99.
• The student spent a total of $18.74, not including tax.

a. Write an equation that can be used to find the cost, X, in dollars, of each pencil.

b. What is the cost of each pencil?

Each pencil cost $1.25

Step-by-step explanation:

$18.74 - $4.99

Then, do $1.25 × 11 and you get $13.75

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
