Answer:
Step-by-step explanation:
Multiply the first bracket by 13
Multiply the second bracket by -4
13(6-x)-4(3x+12)=0
78-13x-12x-48=0
30-25x=0
-25x+30-30=0-30
-25x=-30
Divide by -25 for -25x and-30
x=30/25 reducing: 6/5= 1 1/5
Answer can be 30/25 or 6/5 or 1 1/5
Since you OWE,
the best integer is
-20
Answer: 10 hours
Step-by-step explanation:
Given
Slow fix auto charge $28 for parts and $48 per hour of labor
We work charge $59 for parts and $44.90 per hour of labor
Suppose both works for x hours
Cost of Slow fix= 
Cost of We work= 
When these costs are the same
Answer:
A= 154, B=22
Step-by-step explanation:
if meterorite A is 7 times bigger than B, then our equation would be 7B+B=176. This gives us B=22. Then you multiply 22 times 7 to get your A value.
