Indicate which property is illustrated in Step 2. Step 112x + 2 + 5x + 1=(12x + 2) + (5x + 1)
Step 2 =12x + (2 + 5x) + 1
Step 3 =12x + (5x + 2) + 1
Step 4 =(12x + 5x) + (2 + 1)
Step 5 =(12 + 5)x + (2 + 1)
Step 6 =17x + 3

A.
distributive
B.
associative
C.
arithmetic fact
D.
commutative

The answer is B. Associative.

Step-by-step explanation:

The reason why its B because the associative property states that even if the numbers are regrouped, the answer will still be the same.

I might be wrong

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
