1) u + 2 = 4

u = 2

2)  -5 = s - 3

-2 = s

3) 5/13t = -9

t = -9 × 13/5

t = -39/5

t = -7 4/5

4)  6 = x + 2/3

x = 6 - 2/3

x = 5 1/3

5) 13 + w/7 = -18

w/7 = -18 - 13

w/7 = -31

w = -31 × 7 

w = -217

6) 17 = -13 - 8x

-8x = 17 + 13

-8x = 30

x = 30/-8

x = -15/4

x = - 3 3/4

~Hope I helped!~

*Also, next time, please post your questions individually, so that you could get a quicker answer, thanks! :)

The function f(x) varies inversely with x and f(x)=2 when x = 16.<br><br> What is f(x) when x = 4?
andrew-mc [135]

Answer: The correct answer is:  [D]:  "8" .

Step-by-step explanation:f y varies inversely with x;  then y = k/x ; with "k" being the "constant" in this equation.  

You can find the constant by substituting the values given: x = 16,  f(x) = y = 2 ;

So, f(x) = y = 2  = k/16 ;

→  2 = k / 16 ;

Solve for the constant; "k" ;

Multiply EACH SIDE of the equation by "16"

→  16* (2) = (k / 16) * 16 ;

→  32 = k ;

 ↔  k = 32 ;  

As such, we can write the equation:

y = k/ x ; as:

→  y = 32/ x ;

Since we are given:  "x = 4" ;  Plug in that value; and solve for "y" ;

y = 32/4 = 8 .

y = 8 .

y = f(x) ;

So;  f(x) = 8 ;  which is:  Answer choice:  [D]:  "8" .

What is the mean of the following list of numbers:
erica [24]

Answer:

Mean is the same as average so you simply take 4+5+9+2+104+5+9+2+10+6+7+9+8=180 but for it to be average you also have to divide by the number of values used which in this case is 13 so you take 180/13=13.85 if you round to the second decimal place
