Hey there! :)

Area= length * width

Plug in what you know.

10= 2.5*width

Divide both sides by 2.5

width=4

I hope this helps!

Hello!

We have been given enough information to solve this question!
We know that the length of the rectangle is 2.5, and we also know how to find the area:

A = l × w

But we don't need the area, we need to find the width of the rectangle! You see, we had to multiply the length by the width to find the area.

Now, to find the width, we must flip the problem around and use the opposite of multiplication, which is division.

W = a ÷ l

W = 10 ÷ 2.5

W = 4

Therefore, the width of the rectangle is 4.

chelsea takes the bus to school,but she walks home. the bus travels to the school at an average speed of 45 miles per hour. whil

jekas [21]

For this case, the first thing you should know is:
d: v * t
Where,
d: distance
v: speed
t: time
To go to school by bus we have:
d = 45 * t
To return from school we have:
d = 2.5 * (1-t)
how the distance is the same:45 * t = 2.5 * (1-t)
Answer:
the equation that will help find the time it takes chelsea to get to school on the bus is:
45 * t = 2.5 * (1-t)
Note: the equation will have one solution.
