Answer:
I think either A or B. not sure though
Step-by-step explanation:
Answer: where’s the question
Answer:
1/2(n-5)
9
Step-by-step explanation:
n less 5 = n - 5
if she finds the half of the difference, divide the difference by 2 = 1/2(n-5)
If n = 23
1/2 x (23 - 5)
= 1/2 x 18 = 9
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.
