Answers
Answer:
Step-by-step explanation:
X + (X + 4) + (X - 7) = 54
3X - 3 = 54
3X - 3 + 3 = 54 + 3
3X = 57
3X / 3 = 57 / 3
X = 19
Y = (19 + 4) = 23
Z = (19 - 7) = 12
Sam's age = 19
Dana's age = 23
Alex's age = 12

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

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

Answer:
1029.06
Step-by-step explanation:
You need to change 6% to a decimal
6% = .06
Then multiply .06 by 17,151
0.6 times 17,151 = 1029.06
To Check:
1029.06 out of 17,151
That's pretty much equal to 1/17
As a percentage, 1/17 is 6%
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

after doing that you wanna common the factors from the two pairs. Which is b2+4b-3b-12 then you do you parentheses around b(b+4)-3(b+4) just like that after you do that then you rewrite it in factored form b(b+4)-3(b+4) you then want to rewrite it to this (b-3)(b+4) after that your solution will be (b-3)(b+4) for the first one.

Answers
Answer:
x > 6
Step-by-step explanation:
-2x < -12
divide by -2
switch signs because you're dividing by a negative number
-2x/-2 < -12/-2
x > 6
Hope this helps :)
Answer:
x > 6
Step-by-step explanation:
Solve -2x <-12 for x. Your answer must be a set of real numbers.
Divide both sides by -2. Note that if we here divide by a negative number, we must reverse the direction of the inequality symbol:
-2x < - 12
----- ------
-2 -2
This becomes x > 6, "the solution set"

A) 5n + 10d = 11
B) n + d = 11
C) n + d = 70
D) 5n + 10d = 70
E) 10n + 5d = 70

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 = 70Therefore, the combine equation is as follows:
