Answer:
125
Step-by-step explanation:
The college administrators captured the 90 fraternity men and tagged them, then they returned them to the university campus.
Let there were x tagged fraternity men already on the university campus, so, the total number of tagged fraternity men on the campus become x+90.
Later a group of sorority women captured 215 tagged men, in which the 90 tagged men added by the college administration are included.
So, x+90=215
[tex]\Rightarrow x=215-90=125.[/tex]
Hence, the number of fraternity men on the campus was 125.
the product of 2 more than a number and 10 is 36 more than 8 times the numbe. whats the number?
Answer: 8
Step-by-step explanation:
let x = the number
(x + 2)*10 = 8x + 36
10x + 20 = 8x + 36
2x = 16
x = 8
10x - 4 = 16
What does x equal to?
Answer:
x = 2
Step-by-step explanation:
First isolate the variable:
10x - 4 = 16
+4 +4
10x = 20
Then get x by itself:
10x = 20
x = 20/10
x = 10
4) Choose the correct inequality for this situation.
The Walter family budgets a maximum amount of $124 for a camping trip.
Mr. Walter already spent $40. How many people x can go canoeing if the
cost is $21 per person?
A- 21x + 40 >_ 124
B- 21x + 40 <_124
C- 40x + 21 < _124
D- 21x + 40 > 124
Answer:
B. 21x + 40 ≤ 124
Step-by-step Explanation:
Maximum amount budgeted = $124 (this means they can't spend more than this)
x = number of people
Cost per head = $21
Given that Mr Walter already spent $40, which is part of the money budgeted, the number of people that can go canoeing cam be expressed with the following inequality:
21x + 40 ≤ 124
(note: the amount total to be spent will either be equal to or greater than $124, because it's the maximum amount budgeted for spending).

Working simultaneously, four fudge machines complete a big order in 32 hours. All the machines at the fudge factory work at the same pace. a If only half of the machines are working, in how many hours will the order be complete?
If only half the machines are working at the same rate as before, the order will be finished in 64 hours.
When the four big fridges were working simultaneously, they were able to finish the order in 32 hours.
With only half of these fridges, they will only be half as fast. This means that they will complete the order in double the time:
= 32 x 2
= 64 hours
In conclusion, the order will be completed in 64 hours.

Describe Maysa's error. Explain how you would use a model or place-value concepts to help Maysa build understanding. Give the correct answer in your explanation.
The correct answer for the given subtraction is:
3.5 - 2.46 = 1.04
How to solve the subtraction?
Here we want to find the subtraction between two numbers in decimal form:
3.5 - 2.46 = 1.16
Now, this is clearly wrong, as 0.46 is smaller than 0.5, so the decimals after the decimal point are incorrect, now let's solve it again.
First, we can rewrite these two numbers as:
3.5 = 3 + 0.5
2.46 = 2 + 0.46
Then the subtraction can be rewritten as:
3.5 - 2.46
(3 + 0.5) - (2 + 0.46)
Now we group like terms:
(3 - 2) + (0.5 - 0.46)
1 + (0.50 - 0.46)
1 + (0.04)
Now we group that, so we get:
1 + (0.04) = 1.04
This is the correct answer to the given subtraction.

The cost of a pair of pants was reduced from $50 to $40. By what percent did the cost of the pair of pants decrease? 2% 10% 20% 40%
Answer:
C. 20%
Step-by-step explanation:
50*2=100
40*2=80
100-80=20
A percentage is a number or ratio that represents a fraction of 100.
The percentage decrease in the cost of the pair of pants is 20%.
What is a percentage?A percentage is a number or ratio that represents a fraction of 100.
Example:
50% = 50/100 = 1/2
10% = 10/100 = 1/10
25% = 25/100 = 1/4
20% = 20/100 = 1/5
We have,
The initial cost of pair of pants = $50
The final cost of pair of pants after reduced = $40
The percentage decrease in the cost of pair of pants:
= [( Initial cost - Final cost ) / Initial cost] x 100
= [(50 - 40) / 50] x 100
= (10/50) x 100
= 20%
Thus,
The percentage decrease in the cost of the pair of pants is 20%.

The answer is 0.35 because...
Each row is 10 and there is 3 rows full,
1 row is half full, so that equals 5, and then
you add up all of the numbers and you will get 35.
But, in this case, you need it to be a decimal so you just make it 0.35
