From the statement above, we can say that there is a direct relationship between the number of sheets used to the number of cans that can be made. That is, # of sheets is directly proportional to # of cans. We make an equation as follows:

let y = # of sheets
     x = # of cans

y = kx      where k is the proportionality constant

Assuming linear relationship of the two, we can use either data point as follows:

y = kx
2 = k(36)
k = 1/18

Therefore, the proportionality constant is 1/18.

Simplify each expression then factor the expression 14-28t-5(7+10t)
ludmilkaskok [199]

Answer:

Simplified: -21-98t

Factored: -7(14t+3)

Step-by-step explanation:

The given expresion is:

14-28t-5(7+10t)

We expand the parenthesis to get:

14 - 28t -35 - 70t

We group like terms to get:

14 -35  - 28t- 70t

We combine similar terms to get:

- 21- 98t

We now factor to obtain:

- 21- 98t =  - 7(14t + 3)
