Answer:

Associative property: (71 + 31) + 29 =  (71 + 29) + 31

The total cost would be $131 because you have to add 71 + 31 +29 to find the total cost, which therefore, would be 131.

Step-by-step explanation:

hope that helped

Answer:

Two equivalent expressions: (31 + 71) + 29 = 31 + (71 + 29)

Total cost: $ 131

Harper has $15.00 to spend at her grocery store. She is going to buy bags of fruit that cost $4.75 each and one box of crackers
Andrej [43]
First write the inequality:    15\leq4.75x +3.50

Then to solve, first subtract 3.50 from both sides to get:

11.50\leq4.75x

Then divide by 4.75 to get 2.42, and since you can't buy .42 of a bag  of fruit, you round down. So your final answer would be 2 bags of fruit.

A number is randomly selected from {80, 81, 82, 83, 84, 85, 86}.
Ivan
The probability that the number picked is less than 84 p(A) is:
number of possible events with picked number less than 84/ total number of possible events = 4/7
The complement event of A is that event A does not occur. If the picked number is not less than 84 ( this means is greater than 84 or is 84). The probability of the complement event is:1- p(A)=3/7

Solution: B
