80-32 ÷ 2= 24
( you just do it sdrawkcab)
backwards
3 and 2/5 turns into 17/5
1 and 1/5 turns into 6/5
17+6= 23
23/5 simplifies to 4 and 3/5
Using the quadratic formula works but if you know there are 2 answers (highest power of problem tells you how many solutions) then
10x^2 = 5x
So either x = 0, giving 0=0. Or divide by 5x
2x = 1
x = 0.5
367.5, there are 367.5 8's in 2,940.
Hope this helps, if not, comment below please!!!!
