Answer:
Step-by-step explanation:
x+x+(x+12)=180
3x=180-12=168
x=56
third angle=56+12=68
so angles are 56°,56°,68°
Ashley sold 98 small cups and 57 large cups of lemonade.
Step-by-step explanation:
Given,
Price of small cup of lemonade = $1.25
Price of large cup of lemonade = $2.50
Total cups sold = 155
Total worth of cups = $265
Let,
x represent the number of small cups sold
y represent the number of large cups sold
According to given statement;
x+y=155 Eqn 1
1.25x+2.50y=265 Eqn 2
Multiplying Eqn 1 by 1.25
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 1.25
Putting y=57 in Eqn 1

Answer:
A, B, E
Step-by-step explanation:
The attachment shows a graph of the function. It tends to infinity for x going to infinity in either direction. (A, B are true)
The right-side piece is cubic, not quadratic.
The U-shape tells you the function is decreasing on the left side.
The two function definitions have the same value at x=2, so the function has no discontinuities. It is continuous. (E is true)
