How do I show six less than a quotient of a number and two equals fifteen

Answers

x/2 - 6 = 15

That's how you write it out.

x/2 - 6 = 15
x/2 = 15 + 6
x/2 = 21
x = 21 * 2
x = 42

Answer: 42

First you add 6 on both sides to get x ÷ 2 alone giving you x ÷ 2 = 21. Then to get x alone you have to mutliply 2 on both sides giving you the answer of 42.
(x)/(2)-6=15

Someone please give me the answers...And thank you

Answer:

Step-by-step explanation:

1) 4x + 3 <= 3x - 5

Subtract 3 from both sides

4x + 3-3  <= 3x - 5 -3

4x  <= 3x - 8

Subtract 3x form both sides

4x - 3x <= 3x -3x - 8

x <= -8

Answer:

CHALLENGE ACCEPTED!!

Step-by-step explanation:

4x + 3 ≤ 3x - 5

4x - 3x ≤ -5 -3

x ≤ -8

sorry, cant draw the number line but hope the solution helps.

-2x > 6

-2x ÷ -2 > 6 ÷- 2

x > -3

1/8(3x - 16) < 4

3/8x - 2 < 4

3/8x < 4 + 2

3/8x < 6

x = 16

x - 3/2 ≥ -5

x - 3 ≥ -5 × 2

x - 3 ≥ -10

x ≥ -10 + 3

x ≥ 7

A bag contains 6 red marbles and 30 white marbles. If a representative sample contains 3 red ​marbles, then how many white marbles would you expect it to​ contain?

Answers

there are 36 marbles total.
if the sample contains 3 red marbles, then that is half of the total amount of 6. therefore, half of each color is being taken for the sample. this means that you should expect for there to be 15 while marbles in the sample.

Simplify your answer as much as you can. You can use pi in your answer if necessary (for example, if the answer were $3\pi$, you could enter "3pi" or "3*pi" or "$3\pi$").

Solve for X: 2 ( × - 3 ) = 1.2-x

Answers

when solving an equation, you must do the same thing to both sides or else it won't be equal

when dealing with one unknown (x) try to get the unknown on one side

2(x-3)=1.2-x
distribute or multiply 2 by x then -3

so (2 times x)+(2 times -3[remember negative times positive=negative])
2x-6=1.2-x
add 6 to both sides
2x=7.2-x
add x to both sides
3x=7.2
divide both sides by 3
x=2.4
2(x-3) = 1.2-x
2x-6 = 1.2-x
2x+x = 1.2+6
3x = 7.2
3x/3 = 7.2/3
x = 2.4
