Francisco spent 25 minutes on the internet yesterday is this is 5/6 of the time she spent on the computer how long did she spend on the computer but not on the internet

30 minutes. the easiest way is to use the opposite of the fraction.  divide 25 / 5= 5. now multiply by 6. 5*6= 30.

The answer would be c.8(2)=16-16=0 -8(2)=16-16=0

Remember, you can do anything to an equation as long as you do it to both sidesminus 36 from both sides4.5(8-x)=66-2.5(3x+24)distribute36-4.5x=66-7.5x-60add like terms36-4.5x=-7.5x+6add 7.5x to both sides36+3x=6minus 36 from both sides3x=-30divide both sides by 3x=-10
