Answer:

The correct option is B) Step 3 is incorrect and should be $x=\frac{10}{8}$ .

Step-by-step explanation:

Consider the provided equation.

$6x-1=-2x+9$

Step 1: Use addition property of equality.

$8x-1=9$

Step 2: Use addition property of equality.

$8x=10$

Step 3: Use Division property of equality.

$x=\frac{10}{8}$

Step 4: Now simplify.

$x=\frac{5}{4}$

Now, by comparing these steps with the provided image we can concluded that the step 3 is incorrect.

Thus, the correct option is B) Step 3 is incorrect and should be $x=\frac{10}{8}$ .

Answer:

C. $\frac{1}{18}$

Step-by-step explanation:

Given: Six cards numbered from $1$ to $6$ are placed in an empty bowl. First one card is drawn and then put back into the bowl then a second card is drawn.

To Find: If the cards are drawn at random and if the sum of the numbers on the cards is $8$ , what is the probability that one of the two cards drawn is numbered $5$ .

Solution:

Sample space for sum of cards when two cards are drawn at random is $\{(1,1),(1,2),(1,3)......(6,6)\}$

total number of possible cases $=36$

Sample space when sum of cards is $8$ is $\{(3,5),(5,3),(6,2),(2,6),(4,4)\}$

Total number of possible cases $=5$

Sample space when one of the cards is $5$ is $\{(5,3),(3,5)\}$

Total number of possible cases $=2$

Let A be the event that sum of cards is $8$

$p(\text{A})$ $=\frac{\text{total cases when sum of cards is 8}}{\text{all possible cases}}$

$p(\text{A})=\frac{5}{36}$

Let B be the event when one of the two cards is $5$

probability than one of two cards is $5$ when sum of cards is $8$

$p(\frac{\text{B}}{\text{A}})=\frac{\text{total case when one of the number is 5}}{\text{total case when sum is 8}}$

$p(\frac{\text{B}}{\text{A}})=\frac{2}{5}$

Now,

probability that sum of cards $8$ is and one of cards is $5$

$p(\text{A and B}=p(\text{A})\times p(\frac{\text{B}}{\text{A}})$

$p(\text{A and B})=\frac{5}{36}\times\frac{2}{5}$

$p(\text{A and B})=\frac{1}{18}$

if sum of cards is $8$ then probability that one of the cards is $8$ is $\frac{1}{18}$ , option C is correct.

What is 2 plus 2 minus 17

nataly862011 [7]

<em>The result is -13</em>

<h2>Explanation:</h2><h2 />

Here we have the following addition problem:

$2+2-17$

So let's solve this step by step:

Step 1. Perform two plus two.

$2+2=4$

So:

$2+2-17=4-17$

Step 2. Perform the subtraction.

Since the sign (-) accompanies 17 which is greater than 4, then we perform the subtraction and add the sign (-) to the result. So:

$2+2-17=4-17=-13$

<em>Finally, the result is -13</em>
