Answer:
The angles are 165 and 15
Step-by-step explanation:
Supplementary angles whose sum is 180°
Let A and B be the two supplementary angles.
Let A be the larger angle and B the smaller angle.
From the question, we were told that the large angle (A) is 15 more than 10 times the smaller angle ie
A = 15 + 10B
We can solve for the value of A and B by doing the following:
A + B = 180
But A = 15 + 10B
15 + 10B + B = 180
Collect like terms
10B + B = 180 — 15
11B = 165
Divide both side by the coefficient of B i.e 11
B = 165/11
B = 15
A = 15 + 10B
A = 15 + 10(15)
A = 15 + 150
A = 165
The angles are 165 and 15

Answer:
Store A
Step-by-step explanation:
A) The price per scoop is the slope, or 0.75 dollars, or 75 cents.
B) The slope is y2 - y1 / x2 - x1. Plugging in the values, we get 8-8 / 3-3 = 1. Therefore, the price per scoop is 1 dollar.
C) Two points on the graph are (2,3) and (4,6). Their slope is (6 - 3) / (4 - 2) = 3/2 = 1.5. The price peer scoop is 1.5 dollars.
The cheapest ice cream per scoop is Store A.
hope this helps! <3
