First I made equations for the perimeter (p) in terms of the width (w) and same for the length (l).

Then, since all the sides added together equaled the perimeter, I made the perimeter equation equal to all the sides added together, all in terms of width (no other variables than w).

Solving that algebraically, you can find w. And then plug that back into the equation for length to find length.

w=8, l=11

36/4= 9, 8/4= 2 a is correct

36/2=18, 8/2= 4 b is correct however wrong because it is the simplest distribution

36/8= 4.5, 8/8= 1 c is incorrect

36/11= 3.27, 8/11= .73 d is incorrect.

The first bricklayer can build a wall in 15 days, the second bricklayer can build the same wall in 20 days. How long will it tak

Ugo [173]

Answer:

It takes 8 4/7 days for both bricklayers to build the wall together.

Step-by-step explanation:

The first bricklayer takes 15 days to build the wall, which means it builds 1/15 of the wall per day.

The second bricklayer takes 20 days to build the wall, which means it builds 1/20 of the wall per day.

So if they build the wall together, the expression below will tell how much of the wall they build per day together.

1/15 + 1/20

To add the fractions, we must find a common denominator, which is 60.

4/60 + 3/60, which equals 7/60.

So, they can build 7/60 of the wall per day together. How many days will it take them? We must find how many times 7 fits into 60, which can be done by solving 60/7, which is 8 4/7.

So, it takes 8 4/7 days for both bricklayers to build the wall together.

Make for me number 21 thx

Method One

You could divide by 5 right away.

20/5 = - 3 + x

4 = - 3 + x Add 3 to both sides.

4 + 3 = x

x = 7

Method Two.

You could remove the brackets. This is slightly longer, but some questions can only be solved that way.

20 = 5(-3) + 5x

20 = -15 + 5x Add 15 to both sides

20 + 15 = 5x

35 = 5x Divide by 5

35/5 = x

7 = x

Three buildings in a town are mapped on a coordinate grid. The Cinema is located at (2,1), the Museum is located at (–3,–1), and

balu736 [363]

Answer:

The Cinema is equidistant from the Theater and the Museum

Step-by-step explanation:

Refer to attachment

As per the graph, the three buildings are located on same line, the Cinema (2, 1) is in the middle and the Cinema is equidistant from the Museum (-3,-1) and the Theater (7,3):
2 - (-3) = 5 and 7 - 2 = 5

Correct answer choice:
