What is the mean of 86,90,93,85,79,92

The mean is the average. Just add the numbers.

86 + 90 + 93 + 85 + 79 + 92 = 525

Then divide, you have 6 numbers in your data set so divide by 6.

525 ÷ 6 = 87.5

Hope this helps :)

step-by-step explanation:

i could only see the first page. the other pages were blurry. ; -;

x hot dogs for 2$, y drinks for 3$. 29 items and total 70

2x+3y=70

x+y=29

if x=17and y=12

2(17)+3(12)=70

34+36=70

idk man good luck man
