Fed [463]3 years ago
5 0

Answer:

CB.CA=CD .CK

9(9+2x+5)=10(10+2x+1)

9(2x+14)=10(2x+11)

18x+126=20x+110

126-110=20x-18x

16=2x->x=8

AB=2(18)+5

=21

<u>So, your answer is B) 21</u>

<u>hope it helps...</u>

What is 4 - 7/4x = 1/2? <br>Solve for x.
tia_tia [17]
When evaluating, you must combine like terms first, so subtract 4 from 1/2 then multiply that number by -7/4, this will give you the value of x.

Sarita showed the steps to solving the equation.
shtirl [24]

The option that explains Sarita's mistake is Sarita’s solution is correct. She made an error in her verification.

<h3>What was Sarita's mistake?</h3>

The given equation is: 5(x - 3) + 7(x + 4) = 73

In order to determine the value of x, take the following steps:

1. Apply the Distributive property:

5x - 15 + 7x + 28 = 73

2. Add similar terms together:

12x  + 13 = 73

3. Combine similar terms:

12x = 73 - 13

4. Add similar terms

12x = 60

5. Divide both sides of the equation by 12

x = 60 / 12

x = 5

In order to verify the answer, substitute for x in the given equation :

5(5 - 3) + 7(5 + 4) = 73

5(2) + 7(9) = 73

10 + 63 = 73

73 = 73

kondor19780726 [428]

Answer: negative.


Step-by-step explanation:

We know that the slope of the line \frac{\text{change in y}}{\text{change in x}}

Therefore, the slope for the given data=\frac{y_2-y_1}{x_2-x_1}

\Rightarrow\ Slope=\frac{795-875}{20-10}\\=\frac{-80}{10}\\=-8...,\text{which is negative.}

Hence, the word which describes the slope of the line representing the data in the table = negative.
