You will have to do 9 divided by 80, which is 9/80.
5(x-8)-(x+6)=18
5x-40-x-6=18
4x-46=18
4x=18+46
4x=64
x=16
not sure if this is correct but i hope it helps!!!
Answer:

Step-by-step explanation:
We are given,
.
It is required to find the value of y.
Now, on simplifying above equation, we get,

i.e. 
i.e. 
i.e. 
Hence, the missing term is
.
Roots test tells us to take the factors of the 20 divided by the factors of the coefficient of the the first.
factors of 20 are 1,2,4,5,10,20
factors of 1 are 1
so plus or minus 1/1, 2/1, 4/1, 5/1, 10/1, 20/1 are all possible rational zeros
Answer:
$120.
Step-by-step explanation:
The amount he sells the tool kit for = 80 + 20% of 80
= 80 + 16
= $96.
Let m be the marked price, then
m - 0.20m = 96
0.8m = 96
m = $120.
