Answer:
21
Step-by-step explanation:
Subtract 7 from both sides to get the answer.
Well there many. For instance 3/4 = .74 so 74 / 100 = 37/50
So, 1/2 = .5 so .6 is greaten .5 an less than 3/4, which is .75. We can turn .6 into a fraction like so 6/10 = 3/5 so 3/5 is another fraction.
If you have a list to chose from show the options you have to chose from.
0.5x + 1/5y -3.5x - 4/5 y
0.5x - 3.5x + 1/5 y - 4/5 y. Regroup f/ variable
-3.0x - 3/5 y
We will use the Unitary method to solve this question
304/4=76
Therefore The train travels 76 miles per hour
76*7.5=570
Therefore the train travels 570 miles in 7.5 hours
