<h2>Answer:</h2>

<u>Yes he is correct</u>

<h2>Step-by-step explanation:</h2>

Given a triangle ABC, the sum of the lengths of any two sides of the triangle is greater than the length of the third side. In the words of Euclid: In any triangle two sides taken together in any manner are greater than the remaining one.

If we add the two sides 12 and 18 we get 30 so the third side must be greater than 30. He said greater than 6 so he is right too

padilas [110]
Percentage change = difference/original x 100

(9.00-7.50)/7.50 x 100 = 2.50/7.50 x 100
= 1/3 x 100
= 33.3% increase

During the first year she owned her car, Leslie spent $756 on repairs and maintenance. She spent $1,580 the second year she owne
Drupady [299]

Answer:

109% of increase

Step-by-step explanation:

In order to know the increase in the percentage, we can do this in various methods, however let's follow the method using only rule of 3; you can also do it by the variation index, however, rule of 3 is easier.

First, we need to know the difference between 756$ and 1580$:

1580 - 756 = 824$

Now let's set the rule of three, assuming that 756 is 100% innitial:

756$-------->100%

824$--------> X

Solving for X:

X = 824 * 100 / 756 = 109.9947%

And if you round this number: 109%

Kaitlyn solved the equation for x using the following calculations. Negative 5. 4 x = 12. 2. Minus 5. 4. X = 6. 8. What error, i
Sladkaya [172]

The value of x is 17.6. She should have added 5.4 on both sides to get the correct value of x. Then the correct option is A.

<h3>What is the linear system?</h3>

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

Kaitlyn solved the equation for x using the following calculations.

\rm -5.4 + x =12.2

and she did the calculation will be

\rm -5.4x = 6.8

The mistake she did in this equation is the plus sign is removed between the -5.4 and x. And she subtracted 5.4 from 12.2.

The correct solution of the equation is to add both sides 5.4. Then we have

\begin{aligned} \rm -5.4 + x+5.4 &=12.2+5.4\\\\\rm x &= 17.6\end{aligned}

More about the linear system link is given below.

The price,
attashe74 [19]

Answer:

B

Step-by-step explanation:

You have to look at the second term to be sure of the meaning of t - 15n

What the given term says is that the total number of tickets sold (p) will decrease by 15 times the number of increases that there are.

The other term says that the cost of 1 ticket will increase that each ticket will increase by 2 dollars for each change in the ticket prices providing that change is 2 dollars.

C is out of the question. The information talks about 2 dollars per increase which is the first term.

A is not quite correct. It implies there is exactly 1 ticket increase. The crorect answer is the ticket increases can be a number of times (n)

The answer is B
