Answer:
Step-by-step explanation:
Step one:
given data
time takent= 3.5hours
distance = 60.9miles
the average speed is given as
Average speed= distance/time
Average speed= 60.9/3.5
Average speed= 17.4mph
Step two:
we are told that the speed was actually maintained, so we used the previous value obatained for the following computation
For a time taken as 1 hour, the distance will be
distance= average speed * time
distance= 17.4*1
distance= 17.4 miles
Answer:
Step-by-step explanation: A cyclist rode for 3.5 hours and completed a distance of 60.9 miles. If she kept the same average speed for each hour, how far did she ride in 1 hour?
In order to find Kendrick's biking time to school, set up and solve the equation based on the rate-time-distance relationship, using the given conditions of 5.4 miles distance, x miles per hour speed, and a time of x+15 minutes.
The subject of this question is rate, time, and distance. To find out how long it takes for Kendrick to bike to his school, we should start with the rate-time-distance relationship formula. If we let 'x' be the speed at which Kendrick rides his bike, then the time taken is simply 5.4 divided by x (since distance = rate x time, and we rearrange to get time = distance/rate).
However, the question states that the time is 'x+15' minutes. Therefore, we can set up the equation '5.4/x = x + 15.' Solving this equation will give us 'x' which is both the speed in miles per hour and the time in minutes that it takes Kendrick to bike to school.

Answer:
Part 1) The system of equations that represent this situation is equal to
b+p=42 and 5b+2p=144
Part 2) 20 binders were sold
Step-by-step explanation:
Let
b -----> the number of binders sold
p -----> the number of pencil pouches sold
Part 1)
we know that
The system of equations that represent this situation is equal to
b+p=42
5b+2p=144
Part 2) How many binders were sold?
we have
b+p=42
p=42-b ------> equation A
5b+2p=144 -----> equation B
substitute equation A in equation B
5b+2(42-b)=144
5b+84-2b=144
3b=144-84
3b=60
b=20 binders
Answer:
X=.5
Step-by-step explanation:
put 2x^2+15x-8 into y1 of your calculator and 0 in y2 then second, trace, 5, enter, enter, enter. Then you have your answer
The required value of x is 20.
A proportion is an equation in which two ratios are set equal to each other. In simple words, equivalent fraction are called as proportions.
Now the given equivalent ratios is,
3/12 = 5/x
Cross multiply the ratios we get,
3*x = 5*12
Solve them we obtain,
3x = 60
now dividing both side by 3,
3x/3 = 60/3
Solve them we obtain,
x = 20
So the value of x = 20.
Hence, for equivalent ratios 3/12 and 5/x the valueof x is 20.
