Let the time spent by 181818 people to paint 181818 walls be X. we can calculate for X by using this formula.
666: 343434 minutes
181818:X
cross multiply
666X=343434 x 181818
X=93757482
Answer:
y=27
Step-by-step explanation:
x = k/y
9 = k/6
k = 54
so
2 = 54/y
y= 27
Let the 2 integers be
x and
y.
Their product is 72, so we write:
xy=72. (I)
One of them, say
y, is 2 less than 5 times the other. We can write this as the equation:
y=5x-2. (II)
To find one of numbers, say x, we can substitute y with 5x-2, in the first equation:
xy=72,

expanding the left hand side expression we get:

.
