If you run a marathon of 26 1/5 miles in a time of 5 4/5 how far do you run in 1 hour

To answer this question, we can set up a proportion. Let's convert the values to fractions first:

On the left side will contain the known information, and the right side will contain the unknown - how far you run in an hour:

Then we can cross multiply and solve for x:

Then we can multiply by the reciprocal on the left to cancel out the coefficient and only get x:

So now we know that in 1 hour you will run miles or 0.221 miles.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
