Answer: 10 dimes
Solve using system of equations.
q=number of quarters and d=number of dimes
.25q+.10d=5.50 because the total of dimes and quarters is $5.50
8+d=q because there are 8 more quarters than dimes
substitute 8+d for q into the first equation to get .25(8+d)+.10d=5.50
then simplify
2+.35d=5.50
.35d=3.50
d=10 he has 10 dimes
Answer:
57 degrees
Step-by-step explanation:
Same side interior angles are supplementary which means they both equal 180 degrees.
The correct answer to this question is 0.064.
Here's how to simplify the expression (0.4)^3.
We have to multiply 0.4 three times.
(0.4)^3 = <span>0.4 * 0.4 * 0.4
(0.4)^3 = 0.16 * 0.4
(0.4)^3 = 0.064
The simplified answer is 0.064</span>
Answer:
15-5y
Step-by-step explanation:
To distribute, multiply everything inside the parentheses by the number outside the parentheses.
5(3-y)
Multiply 5 by 3-y
(5*3)+(5*-y)
15-5y
