Answer:
Paula's dog weighs 57lbs and Carla's dog weighs 19lbs
Step-by-step explanation:
So Paula's dog will be "p" and Carla's dog will be "c"
This means p = 3c and that p + c = 76
Replace p with 3c
3c + c = 76
4c = 76
c = 19
Now solve for p
p + (19) = 76
p = 57
Answer:
Her equation system is incorrect
Step-by-step explanation:
Remember that
1 dime=$0.10
1 quarter=$0.25
Let
x------> the number of quarters
y-----> the number of dimes
we know that
0.25x+0.10y=20.70 ------> equation A
x=10+y -----> equation B
Her equation system is incorrect, because in her second equation she exchanged the variables, using x instead of y and y instead of x.
