Answer:

-9/22

Step-by-step explanation:

Cross multiply 3x+1 and x-5 to get 3x^2-14x-5

Cross multiply 3x+2 and x+2 to get 3x^2+8x+4

3x^2-14x-5=3x^2+8x+4

-14x-5=8x+4

-22x=9

x=-9/22

Which of the following describes the correct process for solving the equation 2x − 4 = 20 and arrives at the correct solution? A
Gelneren [198K]

Answer:

<u>The correct answer is A. Add 4 to both sides, and then divide by 2. The solution is x = 12.</u>

Step-by-step explanation:

1. For solving the question and understand which of the statements matches with the solution, let's proceed with the equation:

2x − 4 = 20

2x  - 4 + 4 = 20 + 4 (Adding 4 at both sides)

2x = 24

2x/2 = 24/2 (Dividing by 2 at both sides)

x = 12

<u>The correct answer is A. Add 4 to both sides, and then divide by 2. The solution is x = 12.</u>

<h2><u>DISTRIBUTIVE PROPERTY</u></h2>

The distributive property indicates that multiplying a number by the sum of two addends is equal to multiplying each addend individually by the number and then adding the products together.

In general terms:

<h3>m(n + p) = mn + mp</h3>

‎      ‏‏‎

<u>In this exercise</u>:

Let's apply the distributive property:

\mathsf{2(3w - 5y)}

= \mathsf{2(3w) - 2(5y)}

= \boxed{\mathsf{6w - 10y}}

‎      ‏‏‎

<h3><u>Answer</u>: 6w - 10y</h3>

‎      ‏‏‎
