Answer:
1.26
u(8) - u(2) = 0.74
Step-by-step explanation:
Given
u(x) = ∛x
where x is the number of pancakes consumed per week
and
u(x) is her utility (happiness)
If x = 8
u(8) = ∛8 = 2
Now, if x = 2
u(2) = ∛2 = 1.26
then
u(8) - u(2) = 2 - 1.26 = 0.74
Answer:
144 tickets.
Step-by-step explanation:
So first we have to take the total amount of tickets sold and divide that by 3 (because students bought 2/3 of those tickets and adults bought 1/3 of those tickets). So we get the answer of 144. So that means that the adults bought 144 tickets and the students bought 288 tickets.
2x=5y
x-y=111
x=111+y
so 2x=5y is
2(111+y)=5y
222+2y=5y
2y-5y=-222
-3y=-222 (divide by -3 both sides of the equation)
y=-222/(-3)= 74
x=111+y = 111 +74 = 185
so the first number is 185 and the second is 74
5/10 is one half.
8 is one half of 16.
Or...
x=80/5=16
8 x 10=5x
Using cross multiplication
