Answer:

<em>x</em> = 45 points

Round 3 : 45 points

Step-by-step explanation:

<u>Starting Information:</u>

100 points = 3 rounds

Round 1 : 30 points

Round 2 : 25 points

Round 3 : <em>x</em>

<u>Subtraction:</u>

To find <em>x </em>we need to subtract 30 and 25 from 100

100 - 25 - 30 = <em>x</em> points

<em>Combine -30 and -25 into -55</em>

100 - 55 = <em>x</em>

100 - 55 = 45

In round 3 he scored 45 points

<u>Addition:</u>

To find <em>x</em> we need to add 30 + 25 + <em>x </em>and get a sum of 100

25 + 30 + <em>x </em> = 100

<em>Combine 25 and 30</em>

55 + <em>x</em> = 100

<em>Subtract 55 from each side</em>

<em>x </em>= 45

Here are the 2 expressions I used:

25 + 30 + <em>x</em> = 100

100 - 25 - 30 = <em>x</em>

Note:

My work is not number assigned but hopefully you can understand it :)

Answer:

45 points in round 3

Step-by-step explanation:

x + 30 + 25 = 100

combine like terms

30+25 = 55

x + 55 = 100

  - 55     - 55

--------------------

x = 45

therefore, Amos scored 45 points in round 3

hope this helps! :D

have a MIRACULOUS day, and brainliest is immensely appreciated!! <3

If u(x) = x^5 - x^4 + x^2 and v (x) = -x^2 which expression is equivalent to ( u/ v) (x)
yawa3891 [41]

Answer:

(u/v)(x)=-x^{3}+x^{2}-1

Step-by-step explanation:

You have the following functions:

u(x)=x^{5}-x^{4}+x^{2}\\v(x)=-x^{2}

 Therefore (u/v)(x) indicates that you must divide both functions, as you can see below:

(u/v)(x)=\frac{x^{5}-x^{4}+x^{2}}{-x^{2}}

Simplify it. Therefore, you obtain:

(u/v)(x)=\frac{x^{5}-x^{4}+x^{2}}{-x^{2}}\\\\(u/v)(x)=-x^{3}+x^{2}-1

Tyra made 8 fewer jackets than zack they made 48 jackets altogether how many jackets did zac make
nikitadnepr [17]

Answer:

Zac Made 28 Jackets

Step-by-step explanation:

The way I solved it is by first dividing 48 by 2.

After that I subtracted 8 from Tyra's jackets and then guessed and checked.

I eventually got to the point where i found that Tyra made 20 jackets and Zac made 28 making up to 48 jackets in total.

"Bucket method"
.. (4)*(14%) + (x)*(8%) = (4 +x)*(10%) . . . . . liters and % are in each "bucket"
.. 56 +8x = 40 +10x . . . . . multiply by 100, eliminate parentheses
.. 16 = 2x . . . . . . . . . . . . . . add -40-8x, then divide by 2
.. 8 = x

8 liters of 8% lemonade should be added to make the mixture 10% lemon juice.

A bag contains only red and blue marbles. Yasmine takes one marble at random from the bag. The probability that she takes a red
mamaluj [8]

Let red marbles = X.

The probability is 1 out of 5, written as 1/5

1/5 in terms of red marbles is equal to the number of red marbles divided by 5x, where 5x is the total number of marbles.

1/5 = x/5x 

Now you have 5x total marbles, x red and 4x blue. 

Add 5 more red and the new probability is: 

(x+5)/(5x+5) = 1/3 

Simplify:

3x+15 = 5x+5 

Now solve for x:

Subtract 3x from both sides:

15 = 2x +5

Subtract 5 from each side:

2x = 10 

Divide both sides by 2:

x = 10/2

X = 5

There were originally 5 red marbles.
