Your equation should be
$4(40 tickets) + $5(X) = $400
160 +5x = 400
-160 -160
0 5x = 340
divide both sides by 5
5x/5 = 340/5
x = 68
so they need to sell 68 tickets at the door.
4(40) + 5(68) = 400
160 + 340 + 400
400 + 400
Answer:
2.82 seconds (3 sf)
Step-by-step explanation:
s = ut + 0.5at²
6 = -95(sin25)t + 0.5(32)t²
16t² - 40.14873487t - 6 = 0
t = 2.818501699, -0.1419193751
t is time so can't be negative.
Therefore, t = 2.82s (3 sf)

Answer:
I think 1/4
Step-by-step explanation:
So, you first should find a common denominator so you can add the fractions together.
So, 1/4 + 1/3 + 1/6 becomes 3/12+4/12+2/12.
Add that up, you get 9/12.
Simplify.
9/12 = 3/4
3/4 is how much is dug out. 4/4 - 3/4 is 1/4. That's how much for digging is left, I believe.
