For this case we must give the result obtained by adding three times the number 15 with four times the number 2. For this we have, be "x" the result obtained when making the addition:
What is equivalent to:
Thus, the sum of three times 15 and four times 2 is 53.
Answer:
The sum of three times 15 and four times 2 is: 53.
I feel like the answer is
10h = 110
although it's so simple that I'm not even sure it would be considered an equation.
I got the answer because she works, in total, 10 hours a week. She makes $130 a week, but since $20 comes from the dog walking, you have to do 130 minus 20 which is 110. That's what I did anyway.
5c+10a=3570
c+a=512
...
a=512-c
so ...
5c + 10(512-c)=3570
77.4-15=62.4 62.4/7.8=8, therefore the answer is 9 since the bonus question is later added.
