Use the associative property to create equivalent expressions to a + b + (c + d). Which statements are true? Check all that appl

y. The associative property allows us to change the grouping of terms that are added together. When changing the grouping, the order of the terms stays the same; only the parentheses change position. The expression a + (b + c) + d is an equivalent expression. The expression ab(cd) is an equivalent expression. The expression (a+ b) + c + d is an equivalent expression. The expression a + b(c + d) is an equivalent expression.

Tony is 21 years older than his sister Danielle. In 13 years he will be twice as old as Danielle. How old is each of them now?
Bess [88]

x-y=21 ⇒ x=y+21

x+13=2y

Substitute y+21 for x into the equation x+13=2y

So y+21+13=2y

Simplify 34=y

So Danielle is 34 years old. Plug y back in to the original equation

x-34=21

x=55

Tony is 55 years old
