Answer:
25
Step-by-step explanation:
2x+2+5x+3=180 (angles on a straight line)
7x+5=180
7x=180-5
7x=175
x=25 (dividing both sides by 7)
The model for representing the ratio of the number of orange and green rolls are .
A model that shows the number of orange and green streamers needed to decorate 3 dorm rooms will be 3O=2G
<h3>What is ratio?</h3>

A model that represents the ratio of different colored streamers.
A model that shows the number of orange and green streamers needed to decorate 3 dorm rooms.
D=3O and D=2G
3O=2G
Hence the models are and 3O=2G.

4 friends evenly dividing up a n - slice pizza
So each one get slices of pizza.
For example, if n = 12 slice then each friend gets 12/4 = 3 pieces. If Harris ate one slice less then he ate =3 -1 = 2 pieces.
So the general expression for slices of pizza did Harris eat is
