Find X: Solving Linear Equations With A Variable On Only One Side Of The Equation.

soldi70 [24.7K]

Answer:

x = 22 (see explanation!)

Step-by-step explanation:

Just with any algebraic equation, you will want to isolate the variable (x). Here's a step-by-step to show you how it's done:

1/7(x + 6) = 4

Multiply by 7 to get rid of the 1/7 (since 7 * 1/7 = 7/7 = 1)

7*1/7(x+6) = 7*4

x+6 = 28

Now, subtract 6 from both sides to isolate x:

x + 6 - 6 = 28 - 6

Finally:

x = 22

A bag contains 2 red, 5 blue, and 3 green marbles. A marble is chosen at random. What is the probability of NOT choosing a red m

Lapatulllka [165]

Step-by-step explanation:

Number of red = 2
Number of blue = 5
Number of green = 3

total number of marbles = 10

<h3>probability of not choosing a red marble = 1--choosing a red marble.</h3>

Because probability is always one(1).

Probability =

 $1 - \frac{2}{10}$ 

 $\frac{8}{10}$ 

 $\frac{4}{5}$ 

Is the probability of not choosing a red marble.

x = 72

Step-by-step explanation:

x + (2x - 36) = 180

3x - 36 = 180

3x = 180 + 36

3x = 216

x = 216/3

x = 72
