Answer:
f(13)=2x-1, x=7
Step-by-step explanation:
7*2=14, 14-1=13
vise versa
f(13)=2(7)-1
Answer:
71 + 73 + ..... + 125 = 2,744 = .
Step-by-step explanation:
The smallest set starts at 71. The last term is 125.
The total is 2,744, which is .
Distribute. 32-4x+36=92-6x-48 Then add common factors. 68-4x=44-6x Get the x's on one side. 24=-2x Divide by -2. -12=x is your answer
