Answer:
The answer is letter D
Step-by-step explanation:
Drinks, x, and popcorn, y.
38.75 = 5x+2y
37.25 = 3x + 4y
Let's solve this using the elimination method
subtract the 2nd row from the first
<span>7x=40.2<span>5
divide both sides by 7 to isolate x
</span></span><span>x=5.7<span>5
Substitute x into an equation
</span></span><span><span>10(5.75)+4y=77.5
multiply
</span></span>57.5+4y=77.<span>5
subtract 57.5 from both sides
</span>4y=77.5−57.<span>5
Simplify
</span>4y=2<span>0
divide both sides by 4 to isolate y
y = 5
To check you would plug x and y into the equations and see if it equals properly...
The price of drinks is $5.75, the price of popcorn is $5.
Hope this helps

Answer:
125°, 75°
Step-by-step explanation:
the whole thing = 360°
5x + 3x = 360° - 160°
8x = 200°
x=25°
5x = 125°
3x = 75°
