Y=1/2x+4 and 2y+4=x so substitute y into the second equation to get
2(1/2x + 4) =x
use the distributive property to get x + 8 = x. There is no solution to this equation because x + 8 cannot equal x, and because of this you cannot solve the rest of it so there is no solution.

Answer:

To find the sales tax multiply the purchase price by the sales tax rate. Remember to convert the sales tax rate from a percent to a decimal number. Once the sales tax is calculated, it is added to the purchase price. The result is the total cost—this is what the customer pays.

To receive a grade of A on an 80-question test, 90% of the questions must be answered correctly. What is the maximum number of q
marta [7]

Answer:

The answer would be 8.

Step-by-step explanation:

This is a percentage question, and I have struggled with these before but this is the <em>easiest</em> way to solve it given these certain criteria.

Alright, so it's given that:

A) 90%= an A grade

and

B) This is an 80-question test.

Given these, we can do the following:

90% times 80, which equals <em>72</em>.

Just to check, we know that to convert percentages to fractions, we move the decimal two spots to the left, therefore 90%= 0.90, or 0.9. We take 72 and divide it by 80, and we get 0.9, thus showing that it is correct.

Then, we do 80-72 and using simple math we get 8.

SVETLANKA909090 [29]

According to the text it can be inferred that Passage 2 can be described as providing an explanation for the view of King's speech that is expressed by the author of Passage 1 (option B).

<h3>What explains the terms uplifting...durability?</h3>

According to the information provided in the fragment, edifying universality can be understood as a term that the king includes in his speech. In general, these terms can be explained by referring to the author's explanation in Passage 1.

<h3>What is the statement the author uses to explain the term?</h3>

The statement the author uses to explain the term the King includes in his speech is:

  • "The edifying universality of those four words who hasn't dreamed, and who cannot identify with people whose dreams of a better world are punished with violence helps to explain their durability."

According to the above, lines 76-79 are referring to how the author of Passage 1 explains the King's point of view in his speech.

Note: This question is incomplete. Here is the missing part:

  • "The edifying universality of those four words who hasn't dreamed, and who cannot identify with people whose dreams of a better world are punished with violence helps to explain their durability."

There are exactly three colors of socks in lamont's drawer: red, blue, and green. the current ratio of red to blue to green sock
Harrizon [31]
If the current ratio of red to blue to green socks is 2:3:7, then t<span>here are exactly 2x red socks, 3x blue socks and 7x green socks.
</span>
1. If amount of red socks are increased by n new socks, then t<span>here are exactly 2x+n red socks, 3x blue socks and 7x green socks and (2x+n):3x:7x=8:9:21. This means that 2x+n=8y, 3x=9y, 7x=21y. You have that x=3y and 6y+n=8y, n=2y.
</span>
2. If amount of blue socks are increased by n+2 new socks, then t<span>here are exactly 2x red socks, 3x+n+2 blue socks and 7x green socks and 2x:(3x+n+2):7x=2:4:7. This means that 2x=2t, 3x+n+2=4t, 7x=7t. Now you have that x=t and 3t+n+2=4t, n=t-2.
</span><span>
</span><span>3. Solve x=3y, n=2y, x=t, n=t-2. You obtain that t=3y, t-2=2y. Then 3y-2=2y and y=2. Hence, x=6=t, n=6-2=4.
</span><span>
</span><span>Answer: n=4
