Answer:
<u>13 Quarters and 18 Dimes</u>
Step-by-step explanation:
Let D and Q stand for the numbers of Dimes(D) and Quarters(Q). Give x and y a break, and make it easier to remember which is which.
D + Q = 31
D = Q + 5
Therefore:
D + Q = 31
(Q+5) + Q = 31
2Q + 5 = 31
2Q = 26
<u>Q = 13</u>
<u>Then D = (13+5) or 18</u>
================
Check:
D + Q = 31 ?
18 + 13 = 31 <u>YES</u>
----------------------
D = Q + 5 ?
18 = 13 + 5 <u>YES</u>
Answer:
2. Given
3. Definition of supplementary angles
4. Substitution Property
5 Subtraction Property
Step-by-step explanation:
2. Given
We are given in the statement that m<1 = 112°
3. Definition of supplementary angles
Supplementary angles definition: Two angles are supplementary if there sum is equal to 180°. That statement states:
m<1 + m<2 = 180°
4. Substitution Property
We put the value of m<1 = 112° in the equation. This is substitution property.
5. Subtraction Property
To find the value of m<2 we subtract 112 from both sides of the equation.
This is subtraction property.
