I believe the answer is 26
2x-y=5
Subtract 2x from both sides
-y=-2x+5
Multiply everything by -1
y=2x-5 would be your answer
Answer : y = x + 1
the solution is in the pic below :)
Answer:
8 Hours Because 6×8=48 Plus The Cost Was 10$ You Would Just Do 48 + 10 = 58
Step-by-step explanation:
6 × 8 =48 + 10 = 58
If x = # of quarters, then, the # of dimes will be equal to 2x. The total value (z) would be equal to:
z = 0.25x + 0.10(2x)
Then, since you switch the quarters and the dimes, and you have a new total, the resulting equation will be:
1.2 + z = 0.25(2x) + 0.10(x)
Plug in the values you know:
1.2 + (0.25x + 0.10(2x)) = 0.25(2x) + 0.10(x)
Solve for x:
1.2 + (0.25x + 0.20x) = 0.50x + 0.10x
1.2 + 0.45x = 0.60x
1.2 = 0.15x
x = 1.2/0.15 = 8
This means that there are 8 Quarters in her bag right now. So, the amount of dimes is just 2x which is 16. So your answer will be:
She has 8 Quarters and 16 Dimes in her bag right now. Or, $3.60.
If this doesn't make sense, then tell me. I have some resources where I got the answer from to put it into simplest terms. I have the website if you want.
