Answer:

C = 125

Step-by-step explanation:

Since a straight line is 180 degrees. We can conclude that:

10x + 15 + 5x = 180

And that:

C = 10x + 15

First we need to find the value of x to find C. So,

10x + 15 + 5x = 180

15x + 15 = 180

       - 15    -15

15x         = 165

15x/15     = 165/15

x              = 11

So now, we need to substitute the values of x into C and solve it.

C = 10(11) + 15

   =  110 + 15

   = 125

F(x) = 2x^3 g(x) = x-3<br><br>find f(2)<br>find g(4)<br>find (f+g) (x)<br>​
rjkz [21]

f(x) = 2 {x}^{3}

f(2) = 2 \times  {2}^{3} = 2 \times 8 = 16

_________________________________

g(x) = x - 3

g(4) = 4 - 3 = 1

_________________________________

(f + g)(x) = f(x) + g(x)

(f + g)(x) = 2 {x}^{3} + x - 3

What is 179.3 divided by 61.5 please show work
wariber [46]
(179.3)/(61.5) *10  time both sides by 10 to get rid of the decimal
1793/615
615*2= 1230  615 goes two times into 1793 before exceeding 
1793-1230=563   remainder which is less than 615 hence will give a decimal when divided by 615
563/615= 0.9
2+0.9 = 2.9 is the answer 
for a longer decimal you can easily use a calculator
