Answer:
ok what do you need help with
First do 10 time 10, which gives you a hundred, then add two, and you get 102
The answer is 64
12/1.5 = 8
8 x 8 = 64
G of f means plug f(x) into g(x)
but we want at x=2
we can solve to ways
1) find g(2)=7x-4
= 10
f(10)= 10 / (x-1)
answer is 10/ 9
method 2 is
(f(g)x)= 10/ ((7x-4)-1)
=10/(7x-5)
now x=2
=10/(7(2)-5)
=10/9
same answer, hope this helps
S/2 + 8 = 54
To find out the cost of the spikes, we must isolate the variable.
first, subtract 8 from both sides.
S/2 +8 = 54
-8. -8
Now we have
S/2 = 46
now, to find out what s is on its own, we must multiply by the recipricle of S/2. if that doesn't make sense to you, just think of it as cancelling the division by multiplying by 2.
s/2 = 46
*2. *2
s = 92
The spikes cost $92.
