7x^2-3x+10–4x^2+6x-4
Your answer should be a polynomial in standard form

answer is:

1.75 pounds

what is the question here

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

1) is right
