Mia and Luke made 85 origami together. Mia made 4 pieces of origami every 3 minutes. Luke made 3 pieces of origami every 4 minut
julia-pushkina [17]
For ease of solving, let's first find the rate of Mia and Luke per minute. Since Mia can do 4 pieces every 3 minutes, then she can do \frac{4}{3} of a piece per minute. Luke on the other hand can do \frac{3}{4} of a piece per minute.

To find how many pieces they made, we first need to find the time it took for them to make the pieces. We assign t as the time Mia spent making origami. Since Luke spent 5 more minutes, we can denote his time as t+5.

Putting this into an equation we'll get:
\frac{4}{3}t+ \frac{3}{4}(t+5)=85
\frac{4}{3}t+ \frac{3}{4}t+\frac{15}{4}=85
\frac{25}{12}t=81.25
t=39

Therefore, Mia made pieces of origami for 39 minutes. Knowing this, we can find out the number of pieces of origami she made:
39* \frac{4}{3} =52

ANSWER: Mia made 52 pieces of origami.

Your cellular phone contract calls for a flat monthly service charge of $10.95 plus $0.12 per minute for calls within a certain
wariber [46]

Answer:

For 100 calls the monthly cost = 10.95 + 0.95(100) = $ 22.95

120 calls = 10.95 + 0.95(120) = $ 25.35

140 calls = 10.95 + 0.95(140) = $ 27.75

160 calls = 10.95 + 0.95(160) = $ 30.15

Therefore it is constant

The answer is B. Yes, the average rate of change is constant

Hope this helps!
