For this case, the first thing we must do is define variables.
We have then:
x = number of dimes
y = number of quarters
We write the system of equations:
0.10x + 0.25y = 4.55
x = y
Solving the system we have:
x = 13
y = 13
The value of the dimes is:
(0.10) * (13) = 1.3 $
Answer:
The value of only the dimes is:
1.3 $
Answer:
252,000
Step-by-step explanation:
since we know that 5% of 240,000 is 12,000
then we just add 12,000 to the 240,000 for a 5% increase
The answer is 2 and 9 because 9 divide by that is 4.5
Answer:
3/2 OR 1 1/2
Step-by-step explanation:
Collect like terms, meaning combine both y's. You should have something like this afterwards.
6y = 9
Now that you have that divide the 6 on both sides so Y is by itself!
Your answer is now 3/2.
