Answer: x = 7, x = 1
Step-by-step explanation:
|x-4| = 3
we know either x-4 = 3 or x-4 = -3
x-4 + 4 = 3 + 4
x = 7
x - 4 + 4 = -3 + 4
x = 1
The formula for surface area is SA = 2 (wl + hl + hw). Plugging in the numbers that we know, we get SA = 2 (100 + 10h +10h). We know that the crust accounts for half of the surface area.
The surface area was not provided so this is the closest I can go without the provided surface area. I hope this helps you :)
A + s = 456........a = 456 - s
3.5a + s = 1131
3.5(456 - s) + s = 1131
1596 - 3.5s + s = 1131
-3.5s + s = 1131 - 1596
-2.5s = - 465
s = -465/-2.5
s = 186 <====== student tickets sold
a + s = 456
a + 186 = 456
a = 456 - 186
a = 270 <==== adult tickets sold
It is a percent increase and it increased by 15%
I got this answer by doing 24.61/21.40 which equals 1.15
You can check this answer by doing 21.40 * .15 on a calculator and when you do this you get 3.21 which you can then add back to 21.40 to get $24.61
