What is the next step after using the distributive<br><br> property?
e-lub [12.9K]

Answer:

If it's a simple equation such as 2 (x + y), the next step after applying the distributive property is to do the multiplication and simplify the terms.

But in solving an equation such as

2(x + 3) = 3(x + 1)

After applying the distributive property, the next step is to separate the variables to one side, like collecting like terms and then solving the now simplified equation.

Step-by-step explanation:

For a normal equation, the distributive property, also called the distributive law of division and multiplication helps to use the variable outside the bracket to multiply the sum of terms in the bracket. For example.

2 (x + y)

The distributive property enables us to say

2×x + 2×y = 2x + 2y

So, the next step after applying the distributive property is to simplify the equation.

But in solving an equation such as

2(x + 3) = 3(x + 1)

Applying the distributive property

2x + 6 = 3x + 3

We then operate variables, collect like terms on one side

6 - 3 = 3x - 2x

3 = x

x = 3

Hope this Helps!!!

Write in slope intercept form<br><br> 6x+2y=8
Gwar [14]

Answer:

y = -3x + 4

Step-by-step explanation:

Slope intercept form : y = mx +b

6x + 2y = 8

      2y = -6x + 8

Divide the entire equation by 2

\dfrac{2y}{2}=\dfrac{-6x}{2}+\dfrac{8}{2}

y = -3x + 4

Marlon asks a friend to think of a number from 5-11. What is the probability that marlins friend will think of the number 9
Tju [1.3M]

Answer:

14.29% probability that Marlon's friend will think of the number 9

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, we have that:

There are 7 numbers from 5 to 11(5,6,7,8,9,10,11)

9 is one of them

So

p = \frac{1}{7} = 0.1429

14.29% probability that Marlon's friend will think of the number 9
