Answer:
walks dogs for 3 hours on Saturday and 4 hours on
Sunday. She calculates her total pay to be $57.75.
Which equation could be used to check the reasonableness of her total?
Step-by-step explanation:
jol'
5*(7x + 5y = 29)
<u>+ 21x - 25y = -33
</u>
35x + 25y = 145
<u>+ 21x - 25y = -33</u>
56 x + 0y = 112
56x = 112
x = 2
Plug the x back in to the original equation to solve for y.
7x + 5y = 29
7(2) + 5y = 29
14 + 5y = 29
5y = 15
y = 3
21x - 25y = -33
21(2) - 25y = -33
42 - 25y = -33
-25y = -75
y = 3
x = 2 and y = 3
7,24,25 ~ x,72,75
so x/7 = 72/24 = 75/25 = 3
then x = 7*3 = 21
