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
Answer:
17 green frogs
Step-by-step explanation:
You need to multiply the decimal form of 20% by 85.
To find the decimal form of a percent you take the decimal (20.00) and move it twice to the left (20.00 ---> .2000)
Now, multiply by .2 by 85
(.2)(85) = 17
Therefore, 17 frogs in the pond of 85 frogs are green

Step-by-step explanation:
Given
Required
The graph that shows the number of miles in x hours
We have:
Multiply both sides by x
So, the function is:
This problem can be solved by the chicken rabbits method or you can just do simple algebra.
I.) Chicken and rabbits method
First assume all 110 coins are dimes and none are quarters.
We will have a total value of 11 dollars
Now for each dime we switch out for a quarter, we adds 15 cents to the total value.
18.50-11=7.50 dollars
There are 750/15=50 group of 15 cents in the 7 dollars and 50 cents.
This also meant that we need to switch out 50 dimes for 50 quarters.
So we have 50 quarters.
That first method is very good and very quick once you get the hang of it, now I'm going to show you the algebraic way to solve this.
Let's say there are x dimes and y quarters.
Set up equation
x+y=110
10x+25y=1850
Now solve multiply first equation by 10
10x+10y=1100
subtract
15y=750
y=50
Now we set the numbers of quarters to y so the answer is 50 quarters.
I personally recommend using algebra whenever you can because the practice is very important and you will eventually get really fast at setting up and solving equations. The first method is faster in this case but the second is more generalize, hope it helps.
