There are 720 dishes that need to be rinsed. Josh can rinse them in 72 minutes by himself. It will take his friend Felipe 144 minutes to rinse these dishes. How long will it take them if they rinse these 720 dishes together?
minutes

48 minutes

Step-by-step explanation:

144÷3=48

the answer to this question is 3/19

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
