Answer:
the last one is the answer i think
Step-by-step explanation:
it is the exact same amount but opposite... btw i do flvs too
Example: 863 is the number, when you pass more of 50 is for the other number and if you didn't pass the 50 is for 00.
ex. more than 851 is 900 and lees then 850 is 800
so the answer is 900
20x + 5y = 1900
x + y = 155....multiply by -20
----------------
20x + 5y = 1900
-20x - 20y = - 3100 (result of multiplying by -20)
--------------add
-15y = -1200
y = -1200/-15
y = 80 <== 80 per hr for the mechanic that worked 5 hrs
x + y = 155
x + 80 = 155
x = 155 - 80
x = 75 <== 75 per hr for the mechanic that worked 20 hrs

Hope this helped!! :)
Multiply both sides by 6:
6M = uh
Then divide both sides by h:
u = (6M)/h
