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

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

Reese has nickels and dimes in his pocket. He counts a total of 11 coins. The total value of his pocket change is 70 cents. Let 'n' represent the number of nickels and let d represent the number of dimes in Reese’s pocket.
Which equations can be used to represent the information in this problem? Check all that apply.

A) 5n + 10d = 11
B) n + d = 11
C) n + d = 70
D) 5n + 10d = 70
E) 10n + 5d = 70
REMEMBER, THIS IS MULTIPLE CHOICE :)

Answers

The combine equation that represents the information in this problem is as follows;

n + d = 11

5n + 10d = 70

He has only nickel and dimes in his pocket. The total number of coins is 11 coins. The total cost is 70 cents.

let

n = number of nickels in his pocket

d = number of dimes in his pocket

1 nickel = 5 cents

1 dime = 10 cents

Therefore,

Total number of coins:n + d = 11Total cost of the coins5n + 10d = 70

Therefore, the combine equation is as follows:

n + d = 11

5n + 10d = 70

Step-by-step explanation:

We know the bag has 50 marbles total: (35+15=50)Now, put 15 over 50 to make it a fraction: (15/50)Finally, we figure that 15 divided by 50 equals 0.3.Thus, our answer is 0.3!

The area of a square root is 2.25m2. what is the length of each side of the square?

Show work pls, thank you.

Answers

Answer:

1.5 m

Step-by-step explanation:

Area = length * width

or we can say

Area = side1*side2

since they are the same we can say

Area = side * side

which also means area = side^2

so we have the area and we want the side, we need the inverse operation for squaring something. the inverse of squaring something is square rooting

so

sqrt(Area) = side

so

side = sqrt(2.25)

= 1.5 m

I feel like i made a short story long but i hope it helped =)

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.

Answers

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

X=1 I hope it helps but I’m sorry if it’s wrong
