Answer:
I believe it could be any number because:
let y=any number
x^2+10x+y=16+y
x^2+10x+y-y=16+y-y
x^2+10x=16
you can add any number to both side and not change the solution.
Answer:
Around 1 hour
Explanation:
Ok so we know 15=24 min
and then we know he needs to grade 36 assignments so we can do 15 2x because 15+15=30 then we would have 6 assignments left over but we can do what we already have which is 48 cause 15=24 min so then we do 24+24 cause it’s 15 2x and then we get 48 min with 30 assignments done then we move on to 6 assignments which we have no minutes for so we need to find it so we can do;
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
And
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
And then count by 2 min and cross out 1 assignments each time and then would be 1=2 min 2= 4 min 3=6 min 4= 8 min 5= 10 and 6= 12 min so 6 assignments would be 12 min for 6 assignments so then we do 24-12 and we get 12 so then we do 48+12= 60 and 60 min= an 1 hr so he takes about 1 he to grade the assignments
But then again.... I could be wrong so sry in advance
