F is between C and B. If CF = 7x+4, FB = 10x -69, and CB = 12x -25. Find x and CF​

Answers

Answer 1

Answer:

x = 8CF = 60

Step-by-step explanation:

  CF + FB = CB

  (7x+4) +(10x-69) = (12x-25)

  5x = 40 . . . . . . . . add 65-12x

  x = 8 . . . . . . . . . . divide by 5

  CF = 7x +4 = 7(8) +4 . . . . use the x value in the expression for CF

  CF = 60

Miguel did the following math problem: 65 ∙ 64 = 369. Which of the following is a true statement? 1.He is correct. 2.He is incorrect because he should have subtracted the exponents. 3.He is incorrect because he should have multiplied the exponents. 4.He is incorrect because he multiplied the bases.

Answers

Answer:

He is incorrect.

Step-by-step explanation:

The correct answer is 4,160.

Answer:

3. He is incorrect because he should have multiplied the exponents.

Step-by-step explanation:

6∧5 × 6∧4 = 369 Incorrect

Correct: 6∧5 = 7776

6∧4 = 1296

7776 × 1296 = 10,077,696

1. He is not correct, therefore the first answer is wrong.

2. You do not subtract the exponents unless one of the exponents is negative and you have the same bases. You have the same bases in this equation, however, neither one of them are negative. Therefore, the second answer is wrong.

3. The third answer is correct because if you were adding the two terms together then you would add the exponents together then multiply the base as many times as needed. However, since you are multiplying the two terms together, you also need to multiply the exponents together. From there, you then multiply the terms and get your answer.

4. The fourth answer is also incorrect because you need to multiply the bases together in order to get a correct answer.

E varies directly with G. When G is 6, E is 10. Find the value of G when E is 18.

Answers

Answer:

  10.8

Step-by-step explanation:

E has increased by a factor of 18/10 = 1.8, so G will increase by that factor. The corresponding value of G is ...

  6 × 1.8 = 10.8 = G

__

If you like, you can write an equation relating G to E:

  E = kG

  10 = k(6)

  k = 10/6 = 5/3

Now for E = 18, we have ...

  18 = (5/3)G

  18(3/5) = G = 10.8

Daniela sells handmade purses for $22. She

sells. She has $71 in the bank. How many
purses will she need to sell in order to have a
total of $161 in the bank?

Answers

Answer:

6 purses

Step-by-step explanation

1. Subtract 71 from 161 as that's how much Daniela needs to make to have 161, which is 90

2. Divide 15 by 90 as 15 is the profit, so the answer would be the amount of purses she needs to sell, then you get 6

Plug in the equations in place of the variables

First, subtract k(x) from h(x)

x^2+1-x-2  (combine like terms)

Next, multiply the new equation by 3

18- 12y = -22 -7y solve for y

Answers

Combine like terms: -7y+12y= 5y
18+22=40
Now: 5y=40
Get y alone: 5y/5=40/5
Y=8

Answer: y=8

Step-by-step explanation:

To solve for y, you want to use algebraic properties to isolate y.

18-12y = -22-7y                 [add both sides by 7y]

18-5y=-22                          [subtract both sides by 18]

-5y=-40                              [divide both sides by -5]

y=8

Now, we know that y=8.

Answer:

[tex]x_1=-\frac{3}{2} \\\\x_2=-1[/tex]

Step-by-step explanation:

the general fromula is

[tex](ax+b)(cx+)d)\\\\=acx^{2} +(ad+bc)x+bd[/tex]

so we need that

[tex]ac=2\\\\ad+bc=5\\\\bd=3[/tex]

for ac = 2

we only have 2 and 1

so let's say

[tex]a=2\\\\c=1[/tex]

so we now have

[tex](2x+b)(x+d)\\\\2x^{2} +(2d+b)x+bd\\\\[/tex]

and for bd = 3

we only have 3 and 1

but we need to

2d +b = 5

so we can have

b=3

and

d=1

so the factorized form is

[tex](2x+3)(x+1)[/tex]

so we come back to

[tex](2x+3)(x+1)=0[/tex]

so here we have two cases

Case 1

[tex](2x+3)=0\\\\2x+3=0\\\\2x=-3\\\\x=-\frac{3}{2}[/tex]

Case 2

[tex](x+1)=0\\\\x+1=0\\\\x=-1[/tex]

so those are our solutions

3 -> This is not a variable because its value will always be 3

v -> This is a variable because its value can change once its value changes, the result of the expression will also change

- -> This is not a variable; it is an arithmetic operator to subtract

They may think you know what its like to be a teenager. I mean, they were one at one point in time, but things have changed and have become way more complicated and thats extremely hard for parents to understand.2.Teenagers want more responsibility. There are a huge number of students who just want to graduate high school and move on to the next chapter in their life.3.We lose friends throughout school. Parents always bring up that friend you probably either cant stand anymore, or just drifted apart from. They probably bring it up all the time whether theyre asking, Hows so and-so? or Why dont you talk to this person anymore?. Quit bringing them up! Whats done is done and most likely, that person is not going to come back into our lives.4.We want their attention. Even though we may not show it, we want them to be there for us. Sometimes, we even crave their attention. Whether its us asking how our day was, or cleaning something small around the house, we dont always want our privacy. Sometimes we want you to invade it (to a certain extent).5. Theyre not always going to be the first person we come to when something happens. Were teenagers at this point. We have a lot going on with high school or middle school and its hard. They are not always going to be the first person we come running to when things get bad. We have best friends we like to go to when we have issues we need to talk about.6.Yes we are growing up and eventually, they have to accept that. At this point in life, we are just school kids who are dying to become adults. The last thing we want to hear is our parents telling us that we dont understand yet, or that were not mature enough to do that yet.7.Just because our friends do things you guys dont approve of, doesnt mean we follow in their footsteps.Theyre afraid if we dont hangout with the right crowd, well end up doing bad things. Its understandable for a parent to worry. If we come home acting the same as before we saw that particular friend, were not doing anything wrong.
