Answer:
77
Step-by-step explanation:
10%=11
because you divide 110 by 10.
Then i would multiply that by 3, giving you 33
110-33=77
8n + 22 = 70
-22 -22
8n = 48
n = 48/8
n = 6
n*3 = 3n = 6*3 = 18
3n = 18
The mean can be found by adding the two numbers and dividing by 2
let the second number be y
(x + y)/2 = 1/2x + 1
solve for y
multiply each side by 2
x + y = 2(1/2x + 1)
distribute
x + y = x + 2
subtract x on both sides
y = 2
ANSWER: the second number is 2
I think it is 432.sorry if it is wrong though. My bad calculation error.
