Answer
There is one solution
Step-by-step explanation:
-5(4 - x) = -5x + 20
-20 + 5x = -5x + 20
5x = -5x
Answer: x = 4
Step-by-step explanation:
You basically want to solve for the angle A. Do arcsin of 1/3, which is approximately 19.47 degrees. In this triangle, we are missing the adjacent and opposite, but we do have the angle luckily. Lets use SOH-CAH-TOA.

We can see here that doing sine will give us the length of the opposite
. Do sine of 19.47, then multiply by 12. I got 4
Answer:
D
Step-by-step explanation:
100%-45%=55%
$115*55%=$63.25
X=cost of one box of popcorn.
we can suggest this equation:
3x+1.75=9.25
3x=9.25-1.75
3x=7.5
x=7.5/3
x=2.5
Answer: the equation to find the cost of one box of popcorn is 3x+1.75=9.25, and the cost of one box of popcorn is $2.5.
