Answer: There were 3200 tickets ordered in all .
Step-by-step explanation:
Since we have given that
Number of ordered rolls of tickets =32
Number of tickets in each rolled tickets = 100
So, total number of tickets in all is given by
Hence, there were 3200 tickets ordered in all for the fair.

Answer:
6 hours.
Step-by-step explanation:
The formula sort of has to be invented.
Al
rate = 1 shed / 2 hours
Tom
rate = 1 shed / x hours.
Together.
rate = 1 shed / 1.5 hours.
Equation
1 shed / 2 hours + 1 shed / x hours = 1 shed / 1.5 hours.
1/2 + 1/x = 1/1.5 Put the fractions over a common denominator.
(x + 2) / 2x = 1 / 1.5 Cross Multiply
1.5(x + 2) = 2x Remove the Brackets.
1.5x + 3 = 2x Subtract 1.5x from both sides
3 = 2x - 1.5x
3 = 0.5x Multiply both sides by 2
6 = x
It would take Al 6 hours to do the shed on his own.
Y=x2
Step-by-step explanation:
To find r, we have to isolate it on one side of the equation. We can do this by "undoing" the equation one step at a time.
4r - 8 = 5r + 12
4r - 8 - 4r = 5r + 12 - 4r
-8 = r + 12
-8 - 12 = r + 12 - 12
-20 = r
r = -20
Hope this helps!
