2x+1=5x-44 that would be your equation

next start to simplify 

subtract 1 from both sides so you are left with 2x=5x-45

then subtract 5x from both sides and you have -3x=-45

then finally divide -3 from -45 to get x=15

Answer:

PQ=31\ units

Step-by-step explanation:

we know that

In this problem Q is the midpoint of PR

so

PQ=QR

we have

PQ=2x+1 -----> equation A

QR=5x-44 -----> equation B

equate equation A and equation B

2x+1=5x-44

solve for x

5x-2x=1+44

3x=45

x=15

Find the value of PQ

PQ=2x+1 ------> PQ=2(15)+1=31\ units

exis [7]

Answer:

2 bags of topsoil.

Step-by-step explanation:

The attached figure shows a flower bed.

One bag of topsoil covers 15 square meters.

We need to find how many bags of topsoil does Tom need to cover his flower bed.

The area of the flower bed is :

A=\dfrac{1}{2}\times 12\times 5\\\\=30\ m^2  

Let he has to cover x bags of topsoil. So,

x = Area of flower bed/Area of 1 bag of top soil

x = 30/15

x = 2

Hence, he will need 2 bags of topsoil to cover his flower bed.
