HELP!!! Choose the expression that would be easier to simplify if you used the associative property to change the grouping.
A. 17+[(-41)+(-26)]
O B. 3+G +
C. 67 +(91 +9)
D. (8 + 3) ++

Answer

1) -50

2)11

3)167

4)9

Step-by-step explanation:

 C.

Step-by-step explanation: The associative property states that you will get the same answer for an expression regardless of the way you group it. If we changed 67 + (91 + 9) to (67 + 91) + 9, we would get the same answer for both expressions, 167

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
