Work in rates per hour. These rates can then be added to form an equation

1/13 + 1/10  = 1/x   where  x is the time for both working together

multiply thru by 130x:-

10 x+ 13 x =  130

x = 130/23 =  5.65 hours  or about  6 hours 39 minutes

Wegnerkolmp or someone please help me with this question about slope....
NNADVOKAT [17]

Answer:

The slope is -3/4

Step-by-step explanation:

We need two points to find the slope

We have one point at (0,5) and we have one point at (4,2)

We can use the slope formula

m = (y2-y2)/(x2-x1)

   = (2-5)/( 4-0)

   = -3/4

The slope is -3/4
