Compare. Choose the correct symbol. A) < B) > C) =

Answer:

Step-by-step explanation:

The fractions are equal because we can simplify 3/6 to 1/3 as their biggest common divisor is 3

and

we can simplify 2/4 to 1/2 as their biggest common divisor is 2

So we are using the common divisor to simplify both fractions to solve this problem.

Solve for y:5x-8y=40

bearhunter [10]

Solve for y means we need to isolate y from the equation:

We need to use inverse operations to solve equations:

$\begin{gathered} 5x-8y=40 \\ -8y=40-5x \\ y=\frac{-5}{-8}x+\frac{40}{-8} \\ y=\frac{5}{8}x-5 \end{gathered}$
