1.) A bag of marbles contains only purple and yellow marbles.

The bag has three times as many yellow marbles as purple.

The bag contains 164 total marbles.

Write an equation or system of equations to determine how many of each color of marble is in the bag. (Y=Yellow & P=Purple)

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
