3. How many rides can be taken with the $100 pass? (hint: set up an equation y=mx+b using the cost per ride as your NEGATIVE “m” value because your value goes down each time you ride and $100 as your starting “b” value. We’re solving for x when the total is 0. So, 0 = -___x + 100, fill in the blank with the cost per ride and solve for x.)

b. 10=9.1+0.2x

step-by-step explanation:

that's it

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

answer:

c) the x-coordinate of the center of the circle increases by 3
