The dry cleaning fee for 5 pairs of pants is $20. What is the constant of proportionality? Write an equation to represent the situation. How much will the dry cleaner charge for 8 pairs of pants? Having trouble understanding :,)

The Constant of proportionality is 4.

The equation representing the situation is .

The dry cleaner would charge $32 for 8 pairs of pants.

Step-by-step explanation:

Given:

5 pairs of Jeans = $20

We need to find the constant of proportionality.

Also we need Write an equation to represent the situation.

Also we need to find the dry cleaner charge for 8 pairs of pants

Solution:

Now we will firs find the cost for Dry cleaning 1 pair of jeans.

5 pairs of Jeans = $20

1 pair of jeans = Cost of dry cleaning 1 pair of jeans.

Using Unitary method we get;

Cost of dry cleaning 1 pair of jeans =

Now let the Number of pair of jeans be denoted by 'p'.

Let the cost of dry cleaning be denoted by 'C'.

So we can say that;

Hence the Constant of proportionality is 4.

The equation representing the situation is .

Now we will find the cost of Dry cleaning 8 pairs of pants.

We will substitute p as 8 in above equation we get;

Hence The dry cleaner would charge $32 for 8 pairs of pants.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
