Answer:
Tootsie Rolls = 13
Step-by-step explanation:
Given:
Milky Ways and Tootsie Rolls together were 15 more than the number of Reese's Cups.
There were 4 fewer Reese's Cups than Hershey Bars.
There were 12 Milky Ways and 14 Hershey Bars.
Solution
Milky Ways and Tootsie Rolls = Reese's Cups + 15
There were 4 fewer Reese's Cups than Hershey Bars.
Hershey Bars = 14
Then,
Reese's Cups = 14 - 4
= 10
Milky ways = 12
Hershey bars = 14
Reese's Cups = 10
Milky ways = 12
Milky Ways + Tootsie Rolls = Reese's Cups + 15
12 + Tootsie Rolls = 10 + 15
12 + Tootsie Rolls = 25
Subtract 12 from both sides
Tootsie Rolls = 25 - 12
= 13
Tootsie Rolls = 13
Her change will be $16.22 since 20 +20 is 40 and 40 - 23.78 is 16.22
We are to find the time at which the height of basketball thrown by Eli and Karl is equal. We have the functions which model the heights of both basketballs. So by equating the functions representing the height of both basketballs we can find the value of x from that equation at which the height is same for both basketballs.

Thus after 1.25 seconds the height of basketballs thrown by Eli and Karl will be at the same height. This can be verified by finding the heights of both at x=1.25
For Eli:

For Karl:

Thus height of both basketball is equal after 1.25 seconds
Answer:
see explanation
Step-by-step explanation:
If y is proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k divide both sides by x
k = 
This value must be constant for all ordered pairs, thus
k =
= 
k =
= 
k =
= 
k = 
Since k is constant for all ordered pairs then y is proportional to x
