For the equations given below, which statement is true?
allochka39001 [22]

Answer: C. The equations have the same solution because the second equation can be obtained by adding 6 to both sides of the first equation.

Step-by-step explanation:

You know that the first equation is:

-3x-8=19

And the second equation is:

-3x-2=25

According to the Addition property of equality:

If a=b; then a+c=b+c

Then, you can add 6 to both sides of the first equation to keep it balanced. Then, you get:

-3x-8=19\\\\-3x-8+(6)=19+(6)

-3x-2=25

Therefore, you can observe that the second equation can be obtained by adding 6 to both sides of the first equation, therefore, the equations have the same solution.

If you want to verify this, you can solve for "x" from both equations:

- First equation:

-3x-8=19\\\\-3x=19+8\\\\x=\frac{27}{-3}\\\\x=-9

- Second equation:

-3x-2=25\\\\-3x=25+2\\\\x=\frac{27}{-3}\\\\x=-9

Evaluate the following expression if a=-9, b=-7,c=9 and d=3<br> 2cd + 3ab =
stepladder [879]

Answer:

<h3>The answer is 243.</h3>

Step-by-step explanation:

To evaluate the expression substitute the values of a , b , c and d into the above expression

a = - 9

b = - 7

c = 9

d = 3

So we have

2cd + 3ab = 2(9)(3) + 3(-9)(-7)

= 2(27) + 3( 63)

= 54 + 189

We have the final answer as

<h3>243</h3>

Hope this helps you
