Answer:
25 percent
Step-by-step explanation:
Since the dance team has 9 girls and 3 boys, it is made up of 12 people. 3 of those members are also on the debate team. 12/3 = 4, meaning that a fourth of the dance team is also on the debate team. This translates to 25 percent
8 trees in each row. Twenty four divided evenly by three is eight
Answer:
1.60
Step-by-step explanation:
If we let Q be the number of quarters and N be number of nickels, this is the formula we would use:
[1] 25Q + 5N = 635 (using cents instead of dollars)
We also know something about Q and N.
[2] Q + N = 51
So multiply both sides of the second equation by 5. The reason we do this is because we're going to need to cancel out one of the variables (either Q or N) to solve for the other one. If we multiply times 5, we'll have 5N in both equations.
5Q + 5N = 255
Now we have two equations, and the second one can be subtracted from the first.
25Q + 5N = 635
-(5Q + 5N) = -255
---------------------
20Q = 380
so
Q = 19
There are 19 quarters.
And since there are 51 coins in all, 51-19 = 32 nickels.
the answer of it is $2 the original price
