Please Help Me I Need To Solve By Factoring!!

Answers

Answer 1

Answer:

x=5

Step-by-step explanation:

3x^2=15x

Subtract 15x from both sides

3x^2-15x=0

Factor out 3x

3x(x-5)=0

Since 0 divided by any number is zero, we get that:

x-5=0

x=5

Find the sum of integers from 33 to 47:

Answers

Answer:

Step-by-step explanation:There are formulas to work this out, but you can also suss out an answer by a liberal application of critical thinking.

Okay, you want to add 51 + 52 + 53 + … + 99 + 100, right? (The … represents all the numbers in between, in case you were wondering.)

Well, that’s a total of 50 numbers. And if you know anything about addition, you know that it doesn’t matter what order you add them.

So you could also say 51 + 100 + 52 + 99 + 53 + 98 + … and so on.

Let’s see what happens. 51 + 100 = 151. So far so good.

Then, 52 + 99 also equals 151. And 53 + 98 also equals 151. Since there are 50 numbers, that’s 25 pairs that are going to add up to 151.

151 + 151 + 151 + 151 + … (21 more instances of 151).

So we can simplify our workload a bit. Instead of adding up all the numbers by hand, we can just multiply 151 by 25.

151 x 25 = 3775

From that, we can work out a generic formula that will allow you to add any sequence of numbers…without actually adding.

Let a be the first number in the sequence, and let n be the last number in the sequence. The number of numbers is (n - a) + 1. (You have to add 1, because if you just subtract, it’s like you’re losing the lowest number in the sequence).

So…you get the sum by adding the first and last number in the sequence, and then multiplying that result by half of the total number of numbers.

(a+n)((n−a)+12)  

an−a2+a+n2−an+n2  

−a2+a+n2+n2  

−a(a−1)+n(n+1)2  

Let’s check to see if it works!

−51(51–1)+100(100+1)2  

−51(50)+100(101)2  

−2550+10,1002  

75502  

3775  

Note that if the starting number were 1, the formula would simplify to  n(n+1)2

Following are the calculation to the sum of integers:

Given:

33 to 47

To find:

Sum of integers=?

Solution:

Given numbers:

33 to 47

[tex]\to \bold{33,34,35,36,37,38,39,40,41,42,43,44,45,46,47}[/tex]

Using formula:

[tex]\bold{S = \frac{n(a + l)}{2}}[/tex]

[tex]n=15\\\\a=33\\\\l=47 \\\\ \bold{S = \frac{15(33 + 47)}{2}}\\\\[/tex]

    [tex]\bold{= \frac{15(80)}{2}}\\\\\bold{= \frac{1200}{2}}\\\\\bold{= 600}[/tex]

Therefore, the sum of the integers "600".

The art club is raising money for a new equipment. They need $842.36 to purchase new supplies and have received a $300.00 donation. The remaining amount will be equally divided among 4 different fundraisers throughout the summer. How much money will each fundraiser need to raise in order to purchase the new net and equipment?

Answers

Answer: Each fundraiser need to raise $ 135.59  in order to purchase the new net and equipment.

Step-by-step explanation:

Money required = $ 842.36

Donation amount = $ 300.00

Amount left to arrange  =  (Money required - Donation amount )

= $ (842.36- 300.00)

=  $ 542.36

Number of fundraisers = 4

Money required to arrange by each fundraiser = (Amount left to arrange) ÷4

= $ (542.36÷4)

= $ 135.59

Hence, each fundraiser need to raise $ 135.59  in order to purchase the new net and equipment.

Step-by-step explanation: plug in 6 instead of t in both the equations. Start with the first equation

-300(6)+150000= 148200

Then do the other equation

Subtract both

Consider a square and a regular hexagon (a six sided figure with sides of equal length). One side of the square is 8 feet longer than a side of the hexagon, and the two figures have the same perimeter. What are the lengths of the sides of each figure?

Answers

Answer:

The hexagon has sides of 8 feet and the square 's sides are 16 feet long..

Step-by-step explanation:

If the side of the hexagon is x feet then the side of the square = x+8 feet.

So as the perimeters are equal:

8x = 4(x + 8)

8x = 4x + 32

8x - 4x = 32

4x = 32

x = 8 = side of hexagon so the square side = 16 feet.

lin makes sparkling orange juice by mixing 3 liters of orange juice with 4 liters of soda water. Noah makes sparkling orange juice by mixing 4 liters of orange juice with 5 liters of soda water. How do the two mixtures compare in taste explain your reasoning

Answers

Answer:

Step-by-step explanation:

Lin makes sparkling OJ using the ratio

3:4. Meaning 3L orange juice for every 4L sparkling water.

Noah makes sparkling OJ using the ratio 4:5. Meaning 4L orange juice for 5L sparkling water.

If we said that they both used 12L of orange juice,

Lin would have to use 16L of sparkling water

Noah would have to use 15L of sparkling water

So for the same 12L of orange juice, Lin uses more sparkling water.

Therefore her sparkling OJ would be more diluted (less orange flavour since you added more water) and more bubbly than Noah's.

Use the excerpt from Benjamin Franklins letter to James Parker to answer the question.Excerpt from a letter by Benjamin Franklin to James Parker, March 20, 1751I have, as you desire, read the Manuscript you sent me; and am of Opinion, with the publick-spirited Author, that securing the Friendship of the Indians is of the greatest Consequence to these Colonies; and that the surest Means of doing it, are, to regulate the Indian Trade, so as to convince them, by Experience, that they may have the best and cheapest Goods, and the fairest Dealing from the English; and to unite the several Governments, so as to form a Strength that the Indians may depend on for Protection, in Case of a Rupture with the French; or apprehend great Danger from, if they should break with us. . . .A voluntary Union entered into by the Colonies themselves, I think, would be preferable to one imposd by Parliament; for it would be perhaps not much more difficult to procure, and more easy to alter and improve, as Circumstances should require, and Experience direct. It would be a very strange Thing, if six Nations of ignorant Savages should be capable of forming a Scheme for such an Union, and be able to execute it in such a Manner, as that it has subsisted Ages, and appears indissoluble; and yet that a like Union should be impracticable for ten or a Dozen English Colonies, to whom it is more necessary, and must be more advantageous; and who cannot be supposed to want an equal Understanding of their Interests.Were there a general Council formd by all the Colonies, and a general Governor appointed by the Crown to preside in that Council, or in some Manner to concur with and confirm their Acts, and take Care of the Execution; every Thing relating to Indian Affairs and the Defence of the Colonies, might be properly put under their Management. Each Colony should be represented by as many Members as it pays Sums of Hundred Pounds into the common Treasury for the common Expence; which Treasury would perhaps be best and most equitably supplyd, by an equal Excise on strong Liquors in all the Colonies, the Produce never to be applyd to the private Use of any Colony, but to the general Service. Perhaps if the Council were to meet successively at the Capitals of the several Colonies, they might thereby become better acquainted with the Circumstances, Interests, Strength or Weakness, &c. of all, and thence be able to judge better of Measures proposd from time to time: At least it might be more satisfactory to the Colonies, if this were proposd as a Part of the Scheme; for a Preference might create Jealousy and Dislike.Analyze the excerpt from Benjamin Franklins letter to explain how competition among European powers led to the French and Indian War and encouraged unity among the colonies. Using the excerpt above, answer (A), (B), (C), and (D)A. What reasons does Franklin give for uniting colonial governments? Your response should be 4-6 sentences in length.B. Why does Franklin say that the colonies should come together themselves rather than waiting for the British Crown to appoint a government over them? Your response should be 4-6 sentences in length.
