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
ok done. Thank to me :>

(219,379.01 - x) / x = .3321
Answer:x = 164686.592598
Step-by-step explanation:
219379.01−x/x = 0.3321
−x+219379.01/x = 0.3321
Step 1: Multiply both sides by x.
−x+219379.01≈0.3321x
−x+219379.01 − 0.3321x = 0.3321x−0.3321x (Subtract 0.3321x from both sides)
−1.3321x + 219379.01 = 0
−1.3321x + 219379.01 − 219379.01 = 0 − 219379.01 (Subtract 219379.01 from both sides)
−1.3321x = −219379.01
−1.3321x/−1.3321 = −219379.01/−1.3321
(Divide both sides by -1.3321)
x = 164686.592598
Answer:
164,686.59
Step-by-step explanation:
Carry out the division, then solve for x.
(219,379.01 - x) / x = .3321 . . . . . given
219,379.01/x -1 = 0.3321
219,379.01/x = 1.3321 . . . . add 1
219,379.01/1.3321 = x ≈ 164,686.59 . . . . multiply by x/1.3321
Rounded to 8 significant digits, the value of x is 164,686.59.

YOU BE THE TEACHER Your friend finds the slope of the line shown. Student work is shown. A line graphed on a coordinate plane. The line passes through the points at ordered pair 2 comma 3 and ordered pair 4 comma 1. A calculation is shown for the slope of the line. The first line reads, m equals start fraction 3 minus 1 over 4 minus 2 end fraction. The second line reads, equals start fraction 2 over 2 end fraction. The third line reads, equals 1.
Answer:
The slope of the line is -1
2(3y + 7 + 5) = 196 - 16
what’s the value of y?
And tell me how you know this and why or Y ahahahahahaha
Answer:
y=60
Step-by-step explanation:
196 - 16 = 180
7 + 5 = 12
12 + 3y = 15y
2 * 15y = 30y
180 ÷ 30 = 60
y = 60
Answer:
y=26
Step-by-step explanation:
Let's solve your equation step-by-step.
2(3y+7+5)=196-16
Step 1: Simplify both sides of the equation.
2(3y+7+5)=196-16
(2)(3y)+(2)(7)+(2)(5)=196+-16 (Distribute)
6y+14+10=196+-16
(6y)+(14+10)=(196=-16) (Combine Like Terms)
6y+24=180
Step 2: Subtract 24 from both sides.
6y+24-24=180-24
6y=156
Step 3: Divide both sides by 6.
6y/6 = 156/6
y=26

120 miles/6 gallons = 20 mpg
(20 mpg)(g gallons) = 480 miles
g = 24 gallons
How would you solve this problem? (Worth 10 points, pls help!)
Answer:
(22,0)
Step-by-step explanation:
1. Select any two points given and find their slope (rise/run)
(-38, 40) and (-23, 30)
slope = [tex]\frac{40-30}{-38-(-23)}[/tex] = - 2/3
2. Use the slope and one of the points to create an equation of the line in the format y = mx + b, where m = slope and b = y-intercept.
y = mx + b ⇒ 40 = -2/3 (-38) + b
3. Solve for b
40 = -2/3 (-38) + b
40 = 76/3 + b
40 - 76/3 = b
b = 44/3
4. To find the x-intercept, set y = 0, and solve.
y = -2/3 x + 44/3
0 = -2/3 x + 44/3
2/3 x = 44/3
x = 22

3/4c-7/12+7/24c+2/3-1/6c
simplify the expression
The simplification of the given expression (3/4)c - 7/12 + (7/24)c + 2/3 - (1/6)c is (21/12)c + 1/12.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
A statement expressing the equality of two mathematical expressions is known as an equation.
As per the given expression,
(3/4)c - 7/12 + (7/24)c + 2/3 - (1/6)c
Combined likely terms,
⇒ (3/4)c + (7/24)c - (1/6)c - 7/12 + 2/3
⇒ (3/4 + 7/24 - 1/6)c + 2/3 - 7/12
⇒ [(18 + 28 - 4)/24]c+ (8 - 7)/12
⇒ (42/24)c + 1/12
⇒ (21/12)c + 1/12
Hence "The simplification of the given is (21/12)c + 1/12".

Answer:
x = 5[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
5(x - 3[tex]\frac{3}{4}[/tex] ) = 7[tex]\frac{1}{2}[/tex]
Use distributive property
5x - 18[tex]\frac{3}{4}[/tex] = 7[tex]\frac{1}{2}[/tex]
