7=3/8x-2

move -2 to the other side

sign changes from -2 to +2

7+2=3/8x-2+2

7+2=3/8x

9=3/8x

multiply both sides by 8/3 to get x by itself

9(8/3)=3/8x(8/3)

pretend that 9 has a denominator which is 1

cross out 9 and 3, divide by 3 and then becomes 3*8=24

answer:

x=24

Answer:

x = 24

Step-by-step explanation:

Firstly, isolate x by adding 2 to both sides.

9 = 3/8x

Then, multiply 8 to both sides.

72 = 3x

Then, divide both sides by 3.

24 = x

A boat traveled 27 miles in 2 hrs. At this rate, How many miles will the boat travele in 1/2 hrs
Mashcka [7]

Answer:

In explanation down below.

Step-by-step explanation:

So if the boat was able to travel 27 miles in 2 hours that means that it traveled 13.5 miles an hour. I think that you want to know how many miles the boat will travel in 1/2 an hour. Which is 6.75.  

1 hour: 13.5 miles

1/2 hour the boat has traveled 6.75 miles.

I hope this helps!!!
