11/3 - 2/3 = 9/3 = 3 so he spent 3 more hours reading on saturday than on friday
Hope this helps!
20 markers are needed to cover the 10 kilometers.
Let the 3 numbers be x,x+1,x+2
Given sum of those 3 consecutive integers are 78
X+x+1+x+2=78
3x+3=78
3(x+1)=78
X+1=26
X=26-1
X=25
Therefore the numbers are 25,26,27
I hate quadratic formula it’s so hard
