Answer: 22.14 (22.1428571429)
Step-by-step explanation:
OK
Let's Start with the equation
0.7(x−7)−4.9=5.7
Add 4.9 to both sides
0.7(x-7)=10.6
Divide both sides by 0.7
x-7= 15. 1428571429
Add 7 to both sides
x= 22.1428571429 or 22.14
X= 85 degrees
Y= 45 degrees
Answer:
Wilma has $12.
Step-by-step explanation:
Since we don't know how many hours she worked, we know that Wilma earned 9x dollars at her job. Then she spends $15, so we can just subtract 15 from 9x.
We can just replace the x with 3 to get:
Hence, Wilma has $12.

Answer:
It would be w(3 times 15)
Step-by-step explanation:
The reason is because he gets 15 dollars for every lawn he mows so that's why you would multiply 3 by 15 and the answer to that would be how much he makes in a weeks worth. That is where you would bring in (w) so, if 3 times 15 is 45 and he worked for 1 week 1 times 45 would be how much money he would have made.
