|3.5| = 3.5
Any negative or positive number will always have an absolute value that is positive.
For example, | -3.5| = 3.5
3.5 can also be expressed a fraction.
3.5 * 2/2 = 7/2
Answer:
we have 10 red marbles and 15 white marbles
Step-by-step explanation:
<u>Step 1:</u> Given data
Total marbles = 25
Ratio red: white = 2:3
<u>Step 2:</u> Write an equation
Red marbles = X
White marbles = Y
X+ Y = 25
X = 2/3 Y
2/3 Y + Y = 25
5/3 Y = 25
Y = 15
X =2/3 * 15 = 10
To control this we can plug this in the equation X + Y = 25
10 + 15 = 25
10/15 = 2/3
This means we have 10 red marbles and 15 white marbles
(1) Paris ∈ F. True (Paris is the capital of France)

Answer:
what is the question you are talking about ?
Hello - let's do this step by step. Show your work.
You're asking: 9(8−x)=3x.
Now, simplify both sides of the equation.
9(8−x)=3x
(9)(8)+(9)(−x)=3x (To do that, distribute)
72+−9x=3x
−9x+72=3x
Now, subtract 3x from both sides.
−9x+72−3x=3x−3x
Simplify,
−12x+72=0
After, subtract 72 from both sides.
−12x+72−72=0−72
−12x=−72
Last thing, divide both sides by -12.
-12x/12 = -72/-12
Divide.
Therefore, you have <u>x = 6</u> as your final answer.
