Why is the cost over the amount when finding the unit rate for money? When I put the item over the cost and continue on, I still result in the same answer. Can someone explain this? For example: $3/5 = x/1 x = 0.6 5/$3 = 1/x x = 0.6

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52

This is a rational expression because the denominator contains a variable. this is a polynomial with 3 terms. this is a rational expression because the denominator contains a variable. this is a polynomial with 4 terms. this is a rational expression because the denominator contains a variable. this is a polynomial with 4 terms. this is a rational expression because the denominator contains a variable. this is a polynomial with 3 terms. this is a rational expression because the denominator contains a variable. this is a polynomial with 5 terms.

Talia grouped the terms and factored out the gcf of the groups of the polynomial 15x2 – 3x – 20x + 4. her work is shown below. (15x2 – 3x) + (–20x + 4) 3x(5x – 1) + 4(–5x + 1) talia noticed that she does not have a common factor. what should she do?
