Well divide the number 198 by two so you have two numbers to distribute to. Well the mental math part you use pencil and paper or just take the easy route and use a calculator.
Fog(x)= f(g(x))
g(x) = 2x^2 - 7x - 4
f(x) = x+4
fog(x) = (2x^2 - 7x - 4) + 4
fog(x) = 2x^2 - 7x
hope it helps
<span>Let +a+ = number of trumpet players
Let +b+ = number of saxophone players
---------------------
(1) +a+=+b+-+10+
(2) +b+=+3a+
----------------
Substitute (2) into (1)
(1) +a+=+3a+-+10+
(1) +2a+=+10+
(1) +a+=+5+
and
(2) +b+=+3%2A5+
(2) +b+=+15+
------------------
There are 5 trumpet players
and 15 saxophone players</span>
Answer:
20<
Step-by-step explanation:
We are asked to solve for the value of "x" such that when it is added in the original area of the park it will double the area. Let us compute first the area of the original dog park (A1) and the solution is shown below:
Area = Lenght*Width = L*W where L=30 yards and W=20 yards
Area = 30*20
Area = 600 yards squared
Solving for the x, when x is added to both sides which double the area:
A1*2 = (L + 2x)*W
600*2 = (30+2x)*20
1200 / 20 = 30+2x
60 = 30 + 2x
60-30 = 2x
30/2 =x
15 = x
The value of x is 15 yards.
