Janet = 1/3
Gary = 1/2
(1/3) + (1/2) = 5/6
Let x = time they both can do the job together
(1/2) + (5/6)x = 1
Solve for x to find your answer.
1) the standar form of the equation is ax+by = c, therefore, for y = -2/3x+5, multiply by 3 the previous equation, and its result is 3y = -2x+15⇒ 3y +2x = 15
the final result is 2x+3y = 15
I mean it would be A and D because I don't know why they are both the same answer. If 10 books were sold yesterday, at LEAST 20 are needed to make the goal.
