Joann has a certain number of dimes and quarters in her purse, with a total value of $3.75. The
1 answer:
Answer:
The system of equations 10d+25q=375 and q = 3d-2 can be used to find the numbers of dimes and quarters that Joann has.
Step-by-step explanation:
Given that:
Total value of dimes and quarters = $3.75 = 3.75*100 = 375 cents
One quarter = 25 cents
One dime = 10 cents
Let,
d be the number of dimes
q be the number of quarters
According to given statement,
10d+25q=375
q = 3d-2
Hence,
The system of equations 10d+25q=375 and q = 3d-2 can be used to find the numbers of dimes and quarters that Joann has.

Step-by-step explanation:
- Ray TV bisects ∠RTS, so ∠RTV=∠STV=(16x-6)º
- We also know that ∠RTS=(26x+18)º
- So, (16x-6)º+(16x-6)º=(26x+18)º
- We don't need parenthesis, 16x-6+16x-6=26x+18
- Combine like terms, 32x-12=26x+18
- Add, 32x=26x+30
- Subtract, 6x=30
- Divide, x=5
- ∠RTV now is [16(5)-6]º=(80-6)º=74º
