It’s, 4+x=12. Hope this helps☺️
Answer:
to find the volume of a cylinder
V=π x r^2 x h
now since we want the whole figure were going to add up the two heights to get one height number 4ft + 5ft = 9ft
V= 3.14 x 3^2ft x 9ft
V= 3.14 x 9ft^2 x 9ft
V= 254.34
i tried my best and this is what i know
~batmans wife dun dun dun...
Mike age is 3 less then twice the age of his brother nuke.
M = Mike's age now
N = Nuke's age now
M = 2N - 3
Ten years ago, four times nuke's age was one more mike's age.
M-10 = Mike's age 10 years ago
N-10 = Muke's age 10 years ago
4(N - 10) = 1 + M -10
what are their present ages
find M and N
substitute M = 2N - 3 into 4(N - 10) = 1 + M -10:
4(N - 10) = 1 + [2N - 3] - 10
4N - 40 = 2N - 12
2N = 28
N = 14
M = 2(14) - 3 = 28 - 3 = 25
Mike is 25 and Nuke is 14.
check:
4(14 - 10) = 4(4) = 16 = 26 -10 = 1 + 25 - 10
