<h3>Answer: Line D</h3>

===========================================================

Explanation:

Note in the previous line C that Noah multiplied both sides by 5. This is to clear out the fractions, since each have a denominator of 5.

In line D, Noah only multiplied those outer '5's by the first term in each parenthesis group. He didn't use the distributive property correctly.

The distributive property is a*(b+c) = a*b+a*c.

The 'a' is multiplied to everything inside, which are the terms b and c.

-------------------------------

Here are what the steps should look like from line D and onward. Take note of the 30 and 100. This is from 5*6 = 30 and 5*20 = 100.

D) 7*14 - 30 = 12*14 - 100
E) 98 - 30 = 168 - 100
F) 68 = 68

We end up with the same thing on both sides. So this confirms that x = 14/5 is the solution to the original equation.

Answer:

Relation

Explanation:

The definition of a relation is just a set of ordered pairs.

A function is a relation in which each domain element is paired with exactly one range element.

It can't be a function because if it is a vertical line, then the x-value is the same for the whole line.

A company has a fleet of 200 vehicles. On average, 50 vehicles per year experience property damage. What is the probability that

ICE Princess25 [194]

Answer:

The probability is $\frac{1}{4}$ or 25%

Step-by-step explanation:

The question states the total number of vehicles, as well as the number of damaged vehicles on a yearly basis. If 50 vehicles in every 200 vehicles per year are damaged, then we can obtain:

Probability of a damaged vehicle in any given year = $\frac{Number of Damaged Vehicles}{Total Number of Vehicles}$

= $\frac{50}{200}$ = $\frac{1}{4}$ or 25%

what variable expression should you subtract from both sides of the equation so that you are left with no variables on the right

Scorpion4ik [409]

SOLUTION:

Step 1:

In this question, we are given the following:

Step 2:

The details of the solution are as follows:

What variable expression should you subtract from both sides of the equation so that you are left with no variables on the right-hand side?

The variable expression is: subtract 5x from both sides so that you are left with no variables on the right-hand side

$\begin{gathered} 6x\text{ - 10 = 5x + 15} \\ \text{Subtract 5 x from both sides, we have that:} \\ 6x\text{ - 5x - 10 = 5x - 5x + 15} \\ x\text{ - 10 = 15} \\ \text{Now, add 10 to both sides, we have that:} \\ x\text{ - 10 + 10 = 15 + 10} \\ x\text{ = 25} \\ \text{check:} \\ 6x\text{ - 10 = 5x + 15} \\ \sin ce,\text{ x = 25 , we have that:} \\ 6(25)\text{ - 10 = 5(25) + 15 } \\ 150\text{ - 10 = 125+ 15= 140 ( COR}\R ECT) \end{gathered}$

CONCLUSION:

The final answer is:

$x\text{ = 25}$
