So, to make a mixed number into an improper fraction, you have to multiply the whole number by the denominator and then add the numerator o that number.
2 and 7/10:
2x10=20+7=27/10!
<u>The answer would be B!</u>
I hope this helps!
Answer:
y=4/5x
Step-by-step explanation:
y=mx+b
plug in y and x into each equation and solve!
4=5m+b
8=10m+b
4=5m
m=4/5
b=0
y=4/5x+0
(-y + 5a - 4) + (3y - a - 5) is simplified to 2y + 4a - 11
Answer:
The problem does not work.
Step-by-step explanation:
The plane with speed of 31 mph will cover 640 miles in
hours.
Now, it burns 5 gallons of gas every 3 minutes i.e. 0.05 hours.
So, it will burn in 20.64 hours
gallons.
Now, the helicopter with speed of 45 mph will cover 640 miles in
hours.
Now, it burns 7 gallons of gas every 5 minutes i.e. 0.083 hours.
So, it will burn in 14.22 hours
gallons.
But both of them starts with only 80 gallons of fuel.
Therefore, the problem does not work. (Answer)
