Write a two-column proof to verify each conjecture. If -3r + 1/2=4, then r= -7/6. This is for geometry btw. Any help would be much appreciated, thanks.

every 5 customers that walk in, only 2 buy popcorn.

step-by-step explanation:

basically 2/5.

brainliest would be appreciated.

57.09 minus 7.0435 equals

step-by-step explanation:

just subtrach them both and u get the answer of 50.0465

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

brainliest? ?

here try this one

3a-24=0

combine all like terms then its just a 2 step equation
