The answer for the exercise shown above is the second option, the option B, which is: B. In step 3, the addition property of equality was applied incorrectly.

 
The explanation is:

 
To solve this problem you must apply the proccedure shown below:. You have the followinwg equation:
<span>
  4(m-3)+5(m+2)=m+9 

 Let's review the steps:

 4m-12+5m+10=m+9 (step 1)
 9m-2=m+9 (step 2)
 8m =7 (step 3)  (There is a mistake, because: 9m-m=9+2</span>⇒8m=11)
<span> m=11/8 This should be the step 4</span>

Suppose the side length of square A is 6 inches, and the side length of square B is 9 inches. What is the area of square C if th
Nostrana [21]

Answer:

D.117 square in

Step-by-step explanation:

We are given that

Side length of square A=6 in

Side length of square B=9 in

We have to find the area of square C if the tree squares create a right triangle.

By using Pythagoras theorem

(hypotenuse)^2=(Base)^2+(Perpendicular\;side)^2

Side of square C

(Hypotenuse)^2=6^2+9^2

(Hypotenuse)^2=117

Hypotenuse=\sqrt{117}

Now,

The area of square C=(side)^2

The area of square C=(\sqrt{117})^2=117 in^2

Option D is true.

Choose the correct description of each system of equations.<br> 3x + y = 3<br> x - 2y = 4
DENIUS [597]

Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.

Given the system of equation expressed as:

3x + y = 3

x - 2y = 4

Solve simultaneosly;

3x + y = 3 ............. 1 * 1

x - 2y = 4 ...............2 * 3

_________________________

3x + y = 3

3x - 6y = 12

Subtract

y-(6y) = 3 - 12

7y = -9

y = -9/7

Substitute y = -9/7 into the equation to get x

x - 2y = 4

x - 2(-9/7) = 4

x + 18/7 = 4

x = 4 -  18/7

x = 3/7

Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.
