13.95 hours or 837 min
Step-by-step explanation:
1+ 4/5=9/5 7+3/4=31/4
9/5=1.8; 31/4=7.75
1.8×7.75=13.95 hours
13.95×60min=837min
Just subtract the 1st equation from the 2nd, as follows:
<span> 3x+6y=33
-(</span>3x+4y=19)
-----------------
2y= 14, and y = 7. Sub 7 for y in either of the original equations to obtain the value of x. Write your answer in the form (x, 7).
A million times greater I guess
