The revenue from selling x tickets is r(x) = 10x. The cost for buying x tickets is c(x) = 8x + 40. The profit from selling x tickets is p(x) = r(x) – c(x).9. What is p(x)? *
Answer:
p(x)=2x-40
Step-by-step explanation:
Substitute the variables
p(x)=10x-(8x+40)
p(x)= 10x-8x-40
p(x)=2x-40
Answer:
p(X) = r(X) - c(X).9
⇔ p(X) = 10x - (8x+ 40).9
⇔ p(X) = 10x - 72x - 360
⇔ p(X) = -62x - 360

ASAP solve 21x+6=300 30 points
Answer:
x = 14
Step-by-step explanation:
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression. 21x+6=300 X=14, 21x14=294+6=300.

The sum of two numbers is 240. If one of them
is y find the other number.
Answer:
120?
Step-by-step explanation:
Let's solve the problem step by step: Let's assume the other number is x. According to the problem, the sum of the two numbers is 240. so we can write the equation as: [tex]x + y = 240[/tex]
To find the value of x, we need to substitute the value of y into the equation. Since y is given, we can substitute it. [tex]x + y = 240 x + y = 240 x + y + (-y) = 240 + (-y) x = 240 - y[/tex] Now, we have an equation expressing x in terms of y. To determine the value of x, we need to know the value of y.
Without that information, we cannot calculate the value of x specifically. However, based on the information given, we can conclude that the value of x will be equal to 240 subtracted by the value of y.

Brenda and Cody are selling fruit for a school fundraiser. Customers can buy small boxes of tangerines and large boxes of tangerines. Brenda sold 12 small boxes of tangerines and 1 large box of tangerines for a total of $151. Cody sold 1 small box of tangerines and 3 large boxes of tangerines for a total of $68. Find the cost each of one small box of tangerines and one large box of tangerines
Answer:the cost of a small box of tangerine= $11 and the cost of a large box of tangerine= $19
Step-by-step explanation:
Step 1
Let price of small box of tangerines be represented as x
and price of large box of tangerines be represented as y
Such that the equqtion for Brenda who sold 12 small boxes of tangerines and 1 large box of tangerines for a total of $151 be represented as
12x + y = 151--------equation 1
and
the equation for Cody who 1 small box of tangerines and 3 large boxes of tangerines for a total of $68
x + 3y= 68-------equation 2
Step 2
12x + y = 151--------equation 1
x + 3y= 68-------equation 2
By eliminaton methd multiply equation 2 by 12
x + 3y= 68-------equation 2 x (12)
12x + 36y=816 --------equation 3
Subtract equation 1 from equation 3
12x + 36y=816 --------equation 3
-12x + y = 151--------equation 1
35y=665
y=665/35 =19
to get x , we substitute the value of y=19 into equation2
x + 3y= 68
x+ 3 x 19=68
x=68-57
x=11
Therefore the cost of a small box of tangerine= $11 and the cost of a large box of tangerine= $19

dollars. Which situation can be represented by this
5x < 3x + 2
A The cost of 5 notebooks is greater than the cost of 3 notebooks plus a $2 pen.
B The cost of 5 notebooks is less than the cost of 3 notebooks with a $2-off coupon,
C The cost of 5 notebooks is less than the cost of 3 notebooks plus a $2 pen.
D The cost of 5 notebooks is $2 greater than the price of 3 notebooks.
Answer:
The answer is C.
Step-by-step explanation:
The < sign means that it will be less than so you can remove A and D. But it's not B either because of the $2 off coupon. Off means you would be subtracting meaning it'll look like this 5x < 3x - $2. So the correct answer is C.
Hope this helps!

9514 1404 393
Answer:
1. multiply both sides by 3
2. (a) chose to multiply by 2/3 instead of 3/2; (b) did the multiplications incorrectly, both for the fraction and the integer; (c) x = 9
Step-by-step explanation:
1. If you want to "clear fractions," you multiply by the denominator of the fraction.
3(2/3)x = 3(6)
2x = 18
__
2. The coefficient of x is 2/3. If you want it to be 1, you need to multiply by the multiplicative inverse of 2/3, which is 3/2. Doing that gives ...
(3/2)(2/3)x = (3/2)6
Then simplifying gives ...
x = 18/2 = 9
__
Trey's mistakes were: a) choosing the wrong multiplier; b) carrying out the multiplication incorrectly. (2/3)(2/3) = 4/9, and 6(2/3) = 4. Had Trey done the multiplications correctly, he would have seen that he needed a different multiplier to get to the answer.

Answer the following question
1. Bejar is now known as the city of San Antonio. The author says, “ As one covers the distance from Béjar to this town, he will note that Mexican influence is proportionately
diminished “What cardinal direction can you assume he has traveled from Bejar to reach “This Town"?
2. why might the influence of the Mexican government and culture diminish the further away one travels from Bejar?
3. Terran discovered that the foreigners outnumber the Mexican by what ratio?
4. Who are the “foreigners” that Teran repeatedly refers to?
5. What does Teran predict could happen in Texas if the Mexican government does not strengthen its control over Texas?
Answer: 1.Twelve months have now elapsed since the first half volume of this work was offered to the public. The favourable reception it has experienced gives the Editor reason to hope that he has fulfilled the engagements which he came under at its first appearance, and is a powerful inducement to continue his utmost exertions to preserve and improve the character of the work. In the four volumes which are now published, several extensive and important original articles are introduced, which have not hitherto appeared in any similar collection, and had not even been previously translated into English. These materially contribute towards the ample information which was formerly announced, in the Preface to the first Volume, as a leading object in this Collection. In the subsequent parts of the work, every effort shall be made to fill up its several divisions with original articles of similar interest and equal importance.
Encouraged by a satisfactory and increasing sale, the progress of publication has been somewhat hastened, beyond what was originally promised in the Prospectus and Conditions; as the whole of the fourth Volume is now published, at the period when only its first half was to have appeared. It is intended to repeat this anticipation occasionally, by the publication of two numbers or half-volumes at once, when opportunity offers. While this may gratify one portion of our readers, it is not meant to preclude others from continuing to be supplied, as before, with the numbers or half volumes at regular intervals, in their own option.
2.As the population in Texas from the United States swelled, Mexican authorities grew increasing nervous. In 1827, the Mexican government sent General Manuel de Mier y Terán to investigate the situation. He warned that unless the Mexican government took timely measures, settlers were certain to rebel. Differences in language and culture, Terán believed, had produced bitter enmity between the colonists and native Mexicans. The colonists refused to learn the Spanish language, maintained their own separate schools, and conducted most of their trade with the United States.
3.While holding out the possibility of compromise, the Texans prepared for war. The provisional government elected Sam Houston, a former Tennessee governor, to lead whatever forces he could muster. Then in early 1836, a band of three hundred to five hundred Texans captured Mexico's military headquarters in San Antonio. The Texas revolution was under way.

7x−7=3x−23
Step 1: Subtract 3x from both sides.
7x−7−3x=3x−23−3x
4x−7=−23
