We calculate average by adding up all the data and dividing it by the total number of entries.

Start off by first making an equation like so:

\frac{246+288+234+276+X}{5} = 255, where X = the earnings for the fifth week.

Now multiply both sides by the denominator (5) to get this:

246+288+234+276+X = 1,275

Add up all the known earnings so far:

1,044 + X = 1,275

Subtract the total earnings so far from both sides:

X = 231

Answer: 231

Total=255*5=1275
fifth week earning=1275-(246+288+234+276)
               =231

How do I write x - y = 11 in slope-intercept form?
belka [17]

Answer:

y = x - 11

Step-by-step explanation:

Slope-intercept form:  y = mx + b

<u>Step 1:  Subtract x from both sides</u>

x - y - x = 11 - x

-y = 11 - x

<u>Step 2:  Multiply both sides by -1</u>

-y * -1 = (11 - x) * -1

<em>y = x - 11</em>

<em />

Answer:  y = x - 11

Help please :) <br><br> What is the value of x?<br> Enter your answer in the box<br> x =
lakkis [162]

Answer:

x=27

Step-by-step explanation:

Triangles always add up to 180 so 90+63+x=180 (we know 90 is one of the degrees because of the triangles next to it) Now do some algebra: 90+63+x=180 add 90+63 together> 153+x=180 minus 153 from both sides it'll be x=27

If f(x)=x-1/3 and g(x)=3x+1, what is (fog)(x)
Dafna11 [192]

Answer: 3x+2/3

Step-by-step explanation: Given that f(x)=x-1/3 and g(x)=3x+1

(fog)(x) is the composition of the functions f and g.

(fog)(x)=f(g(x))

            =f(3x+1)  (In the function f(x) where there is x we substitute the x by    

                             3x+1) so that

        (fog)(x) =3x+1-1/3

                      =3x+2/3
