Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
7/8y + 1/2 = 1 1/5
<u>Step 2: Solve for </u><em><u>y</u></em>
- Convert to improper fraction: 7/8y + 1/2 = 6/5
- [Subtraction Property of Equality] Subtract 1/2 on both sides: 7/8y = 7/10
- [Division Property of Equality] Divide 7/8 on both sides: y = 4/5
Step-by-step explanation:
(22 + (-6/20) × (214 - 10 ( -6/20)) - (284.75)
(22 - 6/20) × (214 + 60/20) - (284.75)
(22 - 0.3) × (214 + 3) - (284.75)
(21.7 × 217) - 284.75
4708.9 - 284.75
= 4424.15
Answer:

Answer:
10 quarters and 15 dimes
Step-by-step explanation:
25 = Quarters + Dimes
Total worth = $4.00 = 0.25* Quarter + 0.1*Dimes
so...
25 = Q + D , D = 25 - Q
4 = 0.25*Q + 0.1 * (25 - Q)
4 = 0.25 * Q + 2.5 - 0.1*Q
1.5 = 0.15Q
Q = 10
D = 15
