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

-2x <-12
solve the inequality
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"

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

The area of a square root is 2.25m2. what is the length of each side of the square?
Show work pls, thank you.
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

A bag of marbles contains 35 blue marbles and 15 green marbles. Which of the following shows the decimal of the fraction of green marbles in the bag?
Answer:
15.35
Step-by-step explanation:
Answer:
0.3
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!question 5 please answer

Which multiplication problem is modeled on the number line?
2(– 4)
4(2)
2(4)
4(– 2)
Answer:
4(-2)
Step-by-step explanation:
The correct answer is 4(-2) because the leeps to each number has 2 spaces between them and they are moving to the left of the number line that means that it is -2,and there are 4 leaps.

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 :)
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:
n + d = 11
5n + 10d = 70

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
