Trigonometry and Pythagoras I think
Are you asking how to solve for k? In that case, multiply both sides by 4. Then add 3 to both sides:
(k-3) = 40
k = 43
I do believe the answer is m<30
(1/2) / (1/4) = 1 / x......1/2 wall to 1/4 hr = 1 whole wall to x hrs
cross multiply
(1/2)(x) = (1/4)(1)
1/2x = 1/4
x = 1/4 * 2
x = 2/4 reduces to 1/2....so it will take 1/2 hr (or 30 minutes) to paint the whole wall.
