Ok so the total number of marbles is 150
And these can be either red, green or blue
If they’re are 9 RM, 15GM and 6 BM then the total number of marbles the student picked was 30M
So 150/30 is 5
So 6 * 5 is 30 so the total number of BM is 30

Can someone help me with this math problem, please? Thanks!
vichka [17]
Answer: D, -1
First, plug in the value -1 for x in f(x) first. \frac{1}{(-1)^2+1} can then be simplified to \frac{1}{2} because (-1)^2=1. Next, put the value -1 for x in the equation g(x). This will look like - \frac{1}{2}.

The final step is to evaluate f(x) divided by g(x). f(x) = 1/2 and g(x) = -1/2, so when divided, you get -1.

Wich ratio is equivalent 8) show work<br> 54:18 and 18:6
GarryVolchara [31]
If you are asking which ratio is equivalent to 8 then it is neither.  They are both simplified to 3:1.  54/18= 3, 18/6= 3.  If you were asking if they were equivalent to each other the answer is yes.

Solve for u.<br> -4+2 u = -10<br> Simplify your answer as much as possible.
aliya0001 [1]

Answer:

u = -3

Step-by-step explanation:

Step 1: Write equation

-4 + 2u = -10

Step 2: Solve for <em>u</em>

<u>Add 4 to both sides:</u> 2u = -6

<u>Divide both sides by 2:</u> u = -3

Step 3: Check

<em>Plug in x to verify if it's a solution.</em>

-4 + 2(-3) = -10

-4 - 6 = -10

-10 = -10
