4 t shirts and a hat costs £31 2 t shirts and a hat costs £17
how much does a t shirt cost?
how much does a hat cost?

Step-by-step explanation:

Method:

To work this out we would first need to find the difference between the contents of those two prices. in this case, it is 2 t-shirts.

Now that we know the difference in the contents of both of them is 2 t-shirts, we can work out the value of 2 t-shirts. We can do this by subtracting the value of 17 from 31, this gives us 14. This means that the price of 2 t-shirts= £14.

The next step is to work out the value of one t-shirt. We can do this by dividing the price of 14 by 2, this gives us £7. This is because the price of 2 t-shirts can be represted by and so to work out the value of t we would need to divide by 2.

Now that we know the price of 1 t-shirt is £7, we can now work out the price of 1 hat. To do this we would subtract the price of 2 t-shirts, which is £14, from the end price of £17, this gives us £3. This means that the price of a hat is £3.

Step by Step:

1) Find the difference between the contents.

2 T-shirts

2) Subtract 17 from 31.

3)  Divide 14 by 2.

4) Subtract 14 from 17.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
