Answer:
16 quarters
30 pennies
Step-by-step explanation:
q= quarters
p=pennies
set up a system of equations. One equation is for total value, the other is total # of coins.
q + p = 46
0.25q + 0.01p = 4.30 -> multiply this equation by 4 so you can subtract from the top equation
q + P =46
1q + 0.04p = 17.20
subtract the bottom equation from the top
0.96p = 28.8
divide by 0.96
p=30
substitute p in the top equation
q + 30 = 46
subtract 30 from both sides
q = 16

Step-by-step explanation:
To solve just solve 0.25x +1.50 = 12.00 for x
When I do what the problem statement says, I get 47° for the left angle and 58° for the right one. They are not congruent.
If you change the point's x-coordinate, the point will move either to the left or the right, depending on if the number you change is negative or positive.
