What number makes the sentence below true and how do you come to the answer
(3 +____)+4 =3+(6+4)
review the associative property of addition.
You have three numbers on the right side. Do you suppose the same three numbers would work on the left side? Try it and find out.
Yes, 6.
Did you review the associative property of addition?
To find the missing number that makes the sentence true, we need to solve the equation:
(3 + ____ ) + 4 = 3 + (6 + 4)
First, let's simplify both sides of the equation:
(3 + ____ ) + 4 = 3 + (10)
Next, let's perform the addition on each side:
(____) + 4 = 13
To isolate the variable, we need to get rid of the constant term on the left side of the equation. We can do this by subtracting 4 from both sides:
(____) = 13 - 4
(____) = 9
Therefore, the number that makes the sentence true is 9. To come to the answer, we simplified both sides of the equation and then isolated the variable by eliminating the constant term.
