Answer:
y=6
Step-by-step explanation:
|10-5y|=20
Since the absolute value is isolated, we can then separate the equations
For absolute values, there is a positive and negative when we remove the absolute values.
10-5y = 20 10-5y= -20
Subtract 10 from each side
10-10-5y = 20-10 10-10-5y= -20-10
-5y = 10 -5y = -30
Divide by -5
-5y/-5 =10/-5 -5y = -30/-5
y =-2 y =6
<span>Given:
C -> Umesh's total charge in dollars.
h -> the number of hours he spends on a job.
Hourly charge =$80 /hr
Charge for h hours = 80*h
fixed charge per job = $50
Therefore, C = 80h +50 is the required equation to find the total charges</span>
Answer:
2m+4 is the answer
Step-by-step explanation:
Well.. instead of k he could have put 7. He should know that x and y are cut in half of their original values.
Hope I helped you!
Let's treat the speed in one hour as a variable.
We can say that 1500=12.5x
Divide by 12.5
1500/12.5 = x
x = 120
120 mph is your answer.
