Write the value of n that makes statement true (3+n)+7=3+(6+7)

n = 6

Step-by-step explanation:

First lets combine like terms

(3 + n) + 7 = 3 + (6 + 7)

10 + n = 16

Now let’s subtract 10 on each side to isolate x

N = 6

Now let’s check our work by inputting x just to make sure

(3 + 6) + 7 = 3 + (6 + 7)

9 + 7 = 3 + 13

16 = 16

So we are right!

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
