Question

Q.1)3 + a + b = a + 3 + b is an example of which algebraic property?

Q.2) 5 (x • y) = (5 • x) y is an example of which algebraic property?

Q.3)Complete the Next Step: A partial solution to the equation 8b + 12 = 5(4 + 2b) is given below. Choose the step that is missing from the solution.

8b + 12 = 5(4 + 2b)
????????????
8b = 8 + 10b
−2b = 8
b = −4

A.8b+12=20+2b
B.8b+12=20+10b
C.8b+12=9+7b
D.8b+12=4+10b

Answer 1

start with \[8b + 12 = 5(4 + 2b)\] and then use the distributive property on the left. that will give you the missing step

Answer 2

thank you

Answer 3

yw

Answer 4

btw i meant "distributive property on the RIGHT'

Answer 5

\[5 (x • y) = (5 • x) y \]
variables changed place, that is the "commutative" law

Answer 6

same with first one
