If you formed an algebraic equation to model the statement “three times a number is equal to nine,” how many variables would be in the equation?

The algebraic equation,would be: 3 x n (the variable) = 9.
Therefore, there is one variable in the equation.
Hope this helps!:)

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
