The solution of the equation 2d - 6 = 5 is .

d = 11/2 or 5 1/2

Step-by-step explanation:

2d - 6 = 5

    + 6  + 6

2d = 11

/2     /2

d = 11/2 or 5 1/2

The answer is

Step-by-step explanation:

So the first step in solving is to isolate the variable. To do that we are going to add 6 on both sides. That will cancel out the -6.

2d - 6 = 5

    + 6    + 6

2d = 11

Now, you're left with 2d = 11.

All you have to do now is divide each side by 2.

You get d = 5.5.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
