Answer:
Communitive Property
Step-by-step explanation:
Commutative property = 2 + 3 = 3 + 2 or 2(3) = 3(2)
Associative Property = (2 x 3) 5 = 2 (3 x 5) or (2 + 3) + 5 = 2 + (3 + 5)
Inverse Property = 2 + (-2) = 0 or (2/1)(½) = 1
Basic Definitions:
Commutative Property - Gives you the ability to switch the order of the numbers in an expression.
Associative Property - Let's you move the parenthesis in an expression but not the numbers.
Inverse - Uses numbers like 0 and 1.
Using these basic definitions and examples, we can summarize that the best answer would be Communitive Property

Joseph runs 2 1/2 miles on Monday. Each day after that, he runs the same 1 1/3 mile route every morning. His goal is to run at least 6 miles
by the end of the week. Which inequality represents the least number of days after Monday that Joseph needs to run to reach his goal?
Answer:
The answer is C
Number of days= 21/8
Step-by-step explanation:
The inequality to represent the given situation is [tex]2\frac{1}{2}+1\frac{1}{3} \le6[/tex]. Therefore, option B is the correct answer.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given that, Joseph runs [tex]2\frac{1}{2}[/tex] miles on Monday. Each day after that, he runs the same [tex]1\frac{1}{3}[/tex] mile route every morning.
Let the number of days be x.
Here, the inequality is
[tex]2\frac{1}{2}+1\frac{1}{3} \le6[/tex]
Therefore, option B is the correct answer.

A grocery store offers 10 gas points of gas for every $50 you spend on groceries. For every 10 gas points you earn, you get to take $0.10 off every gallon of gas you buy. Currently, gas is $3.25 per gallon. When Monica fills up her car, she usually puts around 12 gallons of gas in it. How much money must Monica spend at the grocery store to fill up her car for less than $35.00?
Answer: $2,000
Step-by-step explanation:
Gas is $3.25 per gallon. If Monica needs 12 gallons, cost would be:
= 12 * 3.25
= $39
If she wants to fill up for less than $35, she will have to earn the difference in points:
= 39 - 35
= $4
One can get $0.10 off for every $50 spent. The number of 10 cents in $4 is:
= 4 / 0.1
= 40
Monica would therefore have to spend:
= 50 * 40
= $2,000

Pierre had $42 before he paid his club dues. Evaluate the expression 42 − d for d = 25 to find how much money Pierre had left after he spent $25 on dues
Answer:Pierre has $17 left
Step-by-step explanation:
Amount of money before dues = $42
according to the expression 42-d, d represents dues= $25
Amount left = Amount of money before dues - Amount of dues
= $42- $25
=$17
Pierre has $17 left after he spent $25 on dues.
Mathew used his computer for 2 1/8 hours in Tuesday evening and for 2 1/4 hours in Wednesday evening. Which is the best estimate of the time Mathew used his computer on Tuesday and Wednesday evenings
Answer:
About 4 hours. When you add the numbers together, you get
2 1/8 + 2 1/4 = 35/8 = 4 3/8 = 4.375
Step-by-step explanation:
Since the answer is not greater than 4.5, you round down to 4. If the answer was greater than 4.5, you would have rounded up to 5.

There are 96 girls and 72 boys who want to participate in 6th grade intramurals .If each team has the same number of girls and the same number of boys,How many boys and girls will be on each team?
Answer:
by taking Hcf of 96 and 72 we get 4 so each team have 4
'24' teams can be made with each team having 4 girls and 3 boys.
Given that,
No. of girls = 96
No. of boys = 72
Since the number of teams is not given, we will find by finding out the GCF(Greatest Common factor) of 96 and 72.
96 = 2 * 2 * 2 * 2 * 2 * 3
72 = 2 * 2 * 2 * 3 * 3
GCF = 2 * 2 * 2 * 3 = 24
Thus, a maximum of 24 teams can be formed. The number of girls and boys in each of these teams would be:
No. of girls in each team = Total girls/no. of teams
= 96/24
= 4 girls
No. of boys in each team = Total boys/no. of teams
= 72/24
= 3 boys
Thus, each team will have 4 girls and 3 boys.

Answer:
After 7 weeks, Mia's office will have recycled 21 pounds.

With the information provided, you can use a rule of three to find the pounds of paper that Mia's office will have recycled after 7 weeks given that they recycled 9 pounds over 3 weeks.
3 weeks → 9 pounds
7 weeks → x
x=(7*9)/3
x=21
According this, the answer is that after 7 weeks, Mia's office will have recycled 21 pounds.
