How do you solve this?
Answer:
In 7*5 = 35 days, Jack can paint 7 houses.
In 5*7 = 35 days, Richard can paint 5 houses.
So in 35 days, the two of them can paint 12 houses. To paint just one house, they'll need 1/12 the time, or 35/12 = 2 11/12 days.
Step-by-step explanation:
Oy=150-8500m
O y=8500m-150
O y=8500-150m
O y=150m-8500
Answer:the answer is y=8500-150m
Step-by-step explanation:I say this because 150 is the amount of feet that it drops per minute m stands for minute so you would be multiplying 150 by whatever m would be.
The equation representing the airplane's elevation after m minutes is y = 8500 - 150m, where 8500 is the original elevation and 150m is the cumulative loss of elevation.
The question is trying to establish an equation that represents the elevation of the airplane in relation to time. Given the airplane starts at an elevation of 8500 feet and is losing height at the rate of 150 feet per minute, to find the elevation y after m minutes, we need to subtract the total feet lost from the original elevation. Therefore, the equation that represents this situation is: y = 8500 - 150m.
In this equation, 8500 is the original elevation and 150m represents the cumulative loss of elevation for each minute (encompassing m minutes).

Step-by-step explanation:
Let the distance to appoint be s and time for appointment trip be t.
The return trip took one fifth hr longer because of heavy traffic.
Time for return trip = t + one fifth hour = (t + 0.2) hr
Speed of appointment trip = 60 mph
Speed of return trip = 50 mph
We have
s = 60 t and
s = 50 (t + 0.2)
s = 50 t + 10
60t = 50 t + 10
10 t = 10
t = 1 hour
Distance to appointment = 60 t = 60 x 1 = 60 miles
She traveled 60 miles to the appointment place.
Answer:
z ≤ 13
Step-by-step explanation:
note that the symbol ≤ means ' less than or equal to'
then the expression z is less than or equal to can be written as
z ≤ 13
