Virty [35]
Approx - 10% 


72 students signed up for canoeing + the 23 students who signed up for trekking + the 13 students who signed up for both = 108 students 

there are 120 students total, so you have to subtract 120 - 108 = 12 

Now to find the percentage, you have to divide the number of students who didn't sign up for either, by the total 

which is .1 = 10/100 = 10%

Bradley solved the following equation 4(5x - 6) = 2(8x + 10)
lukranit [14]

Hello! I'm guessing you need someone to solve this equation!

4(5x-6)=2(8x+10)

20x-24=16x+20

Add 24 on both sides!

20x=16x+44

Subtract 16x on both sides!

4x=44

Divide 4 by 44

x=11
