9 goes into 81 9 times and 90 10 times so 9/10
F(18)=(1,2,3,6,9,10) f(27) =(1,3,9,27) GCF =9 GCF =250, numbers are 2 (850) and 3 (850) or 1700 and 2550
Answer:
Step-by-step explanation:
So we have the equation:
And we want to find x when y is 9.
So, substitute y for 9 and solve for x:
Multiply:
Add 18 to both sides:
Divide both sides by 2:
So, our answer is 20.5
