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

The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.
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
Find the missing values in the ratio table. Then write the equivalent ratios.

A 6-pack of beaded necklaces costs $12.78. What is the unit price?
$____ per necklace
Please help!! will give brainliest to the correct answer!!
Thanks,
:)
The unit price for 1 pack of beaded necklaces is $2.13.
What is unit price?The unit price refers to the price per unit of measures, such as price per pound, quart, ounce, or other units of weight or volume of the food package.
Given that a 6-pack of beaded necklaces costs $12.78.
We need to find the unit price, for the same.
So the unit price will be calculated by dividing the total cost by number of packets,
= 12.78/6 = 2.13
Hence the unit price for 1 pack of beaded necklaces is $2.13.

The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.
Step-by-step explanation:
Let the athletes be 3x and 2x.
Now, By the question we get,
(3x-12)/(2x+12) = 5/4
or, 12x-48= 10x+60
or, 2x = 108
so, x = 54
now
3x= 3×54= 162
2x = 2×54=108
The number of athletes were 162 in first team and 108 in second team originally.
x is the number of athletes on first team originally ( x > 12, x ∈ Nˣ )
y ----------------------------------------second------------------( y ∈ Nˣ )
The ratio of athletes in the two teams is 3:2
⇒ [tex]\frac{x}{y} =\frac{3}{2}[/tex] (1)
After 12 athletes move from first team to second, the ratio is 5:4
⇒ [tex]\frac{x-12}{y+12} =\frac{5}{4}[/tex] (2)
(1),(2) ⇒ [tex]\left \{ {{\frac{x}{y} =\frac{3}{2}} \atop {\frac{x-12}{y+12} =\frac{5}{4}} \right. <=>\left \{ {{x=162} \atop {y=108}} \right.[/tex]
So: The first team originally has 162 numbers and the second team originally has 108 numbers

Joan represents the height at which a sea gull is flying at +4 feet and the depth at which a fish is swimming at −3 feet on a number line, where 0 represents the surface of the water. Which of these explains whether the sea gull or the fish is closer to the surface of the water? The fish is closer to the surface of the water because |+4| = 4 and |−3| = 3, and 3 < 4. The fish is closer to the surface of the water because |+4| = 4 and − |−3| = −3, and −3 < 4. The sea gull is closer to the surface of the water because |+4| = −4 and |−3| = −3, and −3 > −4. The sea gull is closer to the surface of the water because |+4| = 4 and − |−3| = 3, and 4 > 3.
Answer:
The fish is closer to the surface of the water because |+4| = 4 and |−3| = 3, and 3 < 4.

Jean is x years old and jonathan is y years old how many years older is jean then jonathan. How old was jean 5 years ago
Answer:
x - y is the difference in the kids' ages
x - 5 represents Jean's age 5 years ago
Step-by-step explanation:
If Jean is older, write her age (x) before Jon's age (y): x - y. This is as far as we can go with the limited info you have shared.
Jean is x years old, so 5 years ago her age was x - 5.
