This stuff I don’t understand .PLZ HELPPP MEEE

1. 15

2. 6 × 7 × 4 or 6 × 4 × 7 or 7 × 4 × 6 or 7 × 6 × 4

3. (9 + 5) + 3

4. 11

5. 1

6. 0

Step-by-step explanation:

1. Additive Identity means that if you add 0 with any number, the result would always be the number itself.

2. Commutative Property of Multiplication means that no matter what order, the result would still be the same when the arithmetic operations are all ×.

3. Associative Property of Addition means that no matter where the bracket is placed or which numbers are associated with each other using a bracket, the result would still be the same.

4. Multiplicative Identity means that if you times 1 with any number, the result would always be the number itself.

5. Multiplicative Inverse means that when the denominator of the first fraction is the same as the numerator of the second fraction and the numerator of the first fraction is the same as the denominator of the second fraction, the result would always be 1.

6. If you add the positive of a number with a negative of a number, the result would always be 0.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
