Answer:
4.09
Step-by-step explanation:
4.09 is your answer because all you need to do is add 3.34 and 0.75.
0.75 + 3.34 = 4.09
just substitute 10 into the equation
10=2x-6
add 6 to both sides
16=2x
divide both sides by 2
x=8
This is esay to do when you realize the the speed of mowing is addtive. This is if John mows at 1 lawn / (2/3) hour and Gerge mows at 1 lawn / 1hour, the total speed of mowing is:
1 / (2/3) + 1 = 3/2 + 1 = 5/2
=> 5/2 of lawn per hour
Now, the time is calcualted as the amount of lawn divided by the speed:
1 lawn / (5/2 lawn/hour) = 2/5 hour.
Answer: 2/5 of an hour.
Answer:
B.

To solve for m you would have to square root m and 14, which gives you . This is the best answer for the problem.
