1. Two positive numbers are in a ratio of 3:4. The sum of
three times the first and two
times the second is 68. find
the smaller number?
solution​

its line 2 i just added the rest or else it wouldn't let me answer

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.

130 degrees. i have no other way to explain
