The lcm of 54 and 81 is the smallest positive integer that divides the numbers 54 and 81 without a remainder. Spelled out, it is the least common multiple of 54 and 81
12, 13, 15, 20, 24, 25, 26, 31, 33, 34
First, let's just find everything (minimum, maximum, Q₁, median {Q₂}, Q₃)
Minimum : 12, because it is the lowest number.
Maximum : 34, because it is the highest number.
Median (Q₂) : 24.5, because it is the middle number.
Q₁ : 15, because it is between 24.5 and 34
Q₃ : 31
So,
1) d-12
2) c - 34
3) b-15
4) f-24.5
5) a-31

X=hours master worked
y=hours apprentice worked
62x+40y=492
if master worked 3hours more than apprntice
x=3+y
sub 3+y for x
62(3+y)+40y=492
expand
186+62y+49y=492
186+102y=492
minus 186 both sides
102y=306
divide both sides by 102
y=3
sub back
x=3+y
x=3+3
x=6
master electrician worked 6 hours
6*62=372
master electrician earned $372
(y - yo) = m.(x - xo)
We have the points (4, 12) and (x, 18) with slope of 3.
(18 - 12) = 3.(x - 4)
6 = 3x - 12
3x = 6 + 12
3x = 18
x = 18/3
x = 6
