Answers:
team one = 162team two = 108=========================================================
Explanation:
The ratio 3:2 scales up to 3x:2x for some positive whole number x.
This tells us that the first team has 3x people and the second team has 2x people. We'll subtract 12 from the first team and add 12 to the second team to represent 12 people moving.
3x becomes 3x-122x becomes 2x+12The new team counts 3x-12 and 2x+12 represent team 1 and team 2. Those expressions are in the new proportion 5:4.
This means....
(team 1 new count)/(team 2 new count) = 5/4
(3x-12)/(2x+12) = 5/4
4(3x-12) = 5(2x+12)
12x-48 = 10x+60
12x-10x = 60+48
2x = 108
x = 108/2
x = 54
From this, we then can say:
team 1 original count = 3x = 3*54 = 162team 2 original count = 2x = 2*54 = 108The two subtotals add to 162+108 = 270 players overall.
If we were to subtract 12 from team 1, and add 12 to team 2, then,
team 1 new count = 162-12 = 150team 2 new count = 108+12 = 120The ratio 150:120 then reduces to 5:4 when we divide both parts by the GCF 30. This helps confirm we have the correct answer.
Answer:
162 athletes108 athletesStep-by-step explanation:
Each ratio can be expressed using two numbers that have the same sum. The sum in the first given ratio is 3+2 = 5, and in the second ratio, it is 5+4 = 9. The least common multiple of 5 and 9 is 45, so we can express both ratios so they have a sum of 45:
3 : 2 = 3(9) : 2(9) = 27 : 18
5 : 4 = 5(4) : 4(5) = 25 : 20
Here, we observe that the second ratio has numbers that look like 2 was moved from the numerator to the denominator. (27 -2 = 25; 18 +2 = 20) The problem statement tells us 12 athletes were moved, so multiplying the first ratio by 12/2 = 6 will tell us the numbers of players on each original team:
first team = 27×6 = 162 athletes
second team = 18×6 = 108 athletes

Miss Riley's class has 24 students. She has the students in groups. Each group can have no more than 5 students. if every student has to be in groups how many does she have left?
Answer:
if there can be no more than 5 students, then anything less than 5 students will suffice. However we don’t want any left over ones cause we don’t want that one kid sitting alone during lunch so we can simply put 4 into each group.
Step-by-step explanation:
Hope this helped :DDD
Answer:
6 groups, 4 students in each one
Step-by-step explanation:
The factors of 24 include 6 and 4
That means that you can break 24 into those numbers
You are able to put the students up into groups of 6, with 4 students in each
However, you cannot place the students into groups of 4 (with 6 students in each) because no more than 5 students are allowed in each group

Answer:u need to guess bro
Step-by-step explanation:
11.50 + 1.15x = 12.65
11.50 - 11.50 + 1.15x = 12.65 - 11.50
➗ 1.15x = 1.15 ➗ what does x equal? Please explain in great detail how you figured this out also replace the = with the proper inequality sign and explain how you did that as well.
Answer: the answer is x= 1
Step-by-step explanation:
So we are dealing with 11.50 - 11.50 + 1.15x = 12.65 - 11.50
our first step is Simplify both sides of the equation so:
11.5 + -11.50 + 1.15x = 12.65 + -11.50 turns into:
(1.15x) + (11.5+ -11.5)= (12.65 + -11.5)
**we know 11.5 + -11.5 will cancel each other since they are opposite**
so it will be 1.15x= 1.15
now the very last step is to divide 1.15x on both sides which gives us 1

Answer:
1) 2^9 = 512
2) 2^(3t) = 2^6 for t=2
Step-by-step explanation:
1) An exponent is used to signify repeated multiplication. Here, the factor 2 is repeated 9 times, so the expression can be written using an exponent as ...
2^9
Using any of a variety of means, the value of this expression can be found to be ...
2^9 = 512
__
2) Assuming the bacteria reproduce by multiplying by some factor in a given time, we can divide the original expression into 3 parts:
(2×2×2) × (2×2×2) × (2×2×2)
If this represents the number after 3 hours, then the number after 2 hours is expected to be ...
(2×2×2) × (2×2×2) = 2^6
That is, there will be (2 h)/(3 h) = 2/3 times as many multiplications by a factor of 2. (2/3)(9) = 6 will be the exponent for the number after 2 hours.

Solve for m.
m – 7/8 = 5
Write your answer as a fraction or as a whole or mixed number.
m = ____
Answer:
5 7/8
Step-by-step explanation:
Do the inverse operation.
5 + 7/8 = 5 7/8
Or, do this instead!
Add 7/8 to both sides of the equation. On the side before the equal sign, -78 and +78 cancel out, leaving m all by itself. Bring down the equals sign and we have m = 5 7/8!
Which number line correctly shows –0.8 + 0.6?
A number line going from negative 1.6 to positive 1.6. An arrow goes from negative 0.8 to negative 0.2, and then backwards from 0 to negative 0.8.
A number line going from negative 1.6 to positive 1.6. An arrow goes from 0 to negative 0.8 and then from negative 0.8 to negative 1.4.
A number line going from negative 1.6 to positive 1.6. An arrow goes from 0 to 0.8 and then from 0.8 to 1.4.
A number line going from negative 1.6 to positive 1.6. An arrow goes from negative 0.6 to 0.2 and then from 0 to negative 0.6.
Mark this and return
Answer:
Step-by-step explanation:
Since -0.8 is located to the left of origin so when adding any value it will cause it to shift to the right. For example, add 0.1 to 0.8, we get a value of 0.7 shifting the arrow to the right, same goes for 0.2
-0.8 + 0.1 = -0.7
-0.8 + 0.2 = -0.6
-0.8 + 0.4 = -0.4
-0.8 + 0.6 = -0.2
In this way it ends at -0.2

Minh and Mikayla are selling wrapping paper for a school fund-raiser. Customers can
buy either packages of folded paper or rolls of paper. Minh sold 6 rolls of paper and 2
packages of folded paper for a total of $44. Mikayla sold 3 rolls of paper and 9 packages
of folded paper for a total of $54. How much does each roll cost? How much does each
package of folded paper cost?
Answer:
Let x=rolls of paper,y=folded paper:
6x+2y=44
3x+9y=54
-------
6x+2y=44
6x+18y=108
16y=108-44=64
y=4
x=6
Thus, a roll of paper cost $6,folded paper was $4 each

Answer:
2.5x > 25
Step-by-step explanation:
1. 10 + 2.5x > 35
2. 10 + 2.5x - 10 > 35 - 10 (Subtracting 10 from both sides)
3. 2.5x +10 - 10 > 35 - 10 (Group like terms)
4. 2.5x > 35 - 10 (Simplify the arithmetic)
5. 2.5x > 25

What is the perimeter of a rectangle with a length of 15 ft and a width of 32 ft?
A. 47 ft
B. 55 ft
C. 94 ft
D. 480 ft
Answer:
C) 94 ft
Step-by-step explanation:
The perimeter of a rectangle's formula is:
[tex]P = 2l + 2w / P = 2(l+w)[/tex]
I will use the second formula.
We are given the length of 15ft and a width of 32 ft.
[tex]P = 2(15 + 32)\\\rule{150}{0.5}\\P = 2(47)\\\\P = \boxed{94}[/tex]
The answer should be C.
Hope this helps.
