Answer:
3x+3=-36 is the equation
The answer is -13,-12,-11
Step-by-step explanation:
So consecutive integers, so lets say it’s x, if it’s consective it means the next number after, (Ex: 1,2,3,4,5) so the pattern is x+x+1+x+2 and so on. In this a
cade it’s 3 numbers so x+x+1+x+2 which is 3x+3.
Were trying to find -36 so 3x+3=-36
Solve the equation and you’ll get -13.
Add 1 to -13 and add 2 to -13 and you have your 3 consecutive numbers!
-13+1=-12 -13+2=-11. The original is -13
check: -13+-12+-11=-36 is correct
The equation is
3x+3=-36
Answer:
64
Step-by-step explanation:
we have given that mean of 9 students is 84
so total score of 9 students = mean×9
=84×9=756
and we have given mean score of exam is 82 and there is total 10 students so the total score of 10 students =10×82
=820
so the unreadable score = score of 10 students -score of 9 students =820-756=64
