18 kids total.
4 : 5
4+5=9
18 divided by 9 = 2
Each unit = 2
4 times 2 = 8, so there are 8 girls
5 times 2 = 10, so there are 10 boys.

Given the definitions of f(x) and g(x) below, find the value of g( f(-5)).
tensa zangetsu [6.8K]

Answer:

we conclude that:

  • g(f(-5)) = 30

Step-by-step explanation:

Given

f(x) = x+9

g(x) = x² + 7x – 14

To determine

g(f(-5)) = ?

First, we need to find f(-5)

f(x) = x+9

substitute x = -5

f(-5) = (-5)+9

f(-5) = -5+9

f(-5) = 4

so

g(f(-5)) = g(4)

Now, we need to find g(4)

g(x) = x² + 7x – 14​

substitute x = 4

g(4) = (4)² + 7(4) - 14

g(4) = 16 + 28 - 14

g(4) = 30

i.e.

g(f(-5)) = g(4) = 30

Therefore, we conclude that:

  • g(f(-5)) = 30

I NEED ASAP:<br> What is the value of x?
Vitek1552 [10]

Answer:

x=48

Step-by-step explanation:

10x-20+6x+8=180 set the equations together and to equal 180 since a line is 180 degrees

Get the variables together

10x-20+6x+8=180

-6x       -6x

4x-20+8=180

add together -20 and 8

4x-12=180

add -12 on each side

4x-12=180

   +12  +12

4x=192

divide all by 4

x=48
