Complete the statement If x/7 = 5/3, then x+7/7 =?

Mathematics

Lets get started :)

\frac{x}{7} = \frac{5}{3}
We can cross multiply, to find the value of x
3x = 7 x 5
3x = 35
We have to divide by 3 on either sides to isolate x
\frac{3x}{3} =  \frac{35}{3}
3 and 3 cancels out

x = \frac{35}{3}

Then, x + \frac{7}{7}  ( 7 divided by 7 is 1)
\frac{35}{3} + 1   = \frac{38}{3}

Ronch [10]

If 1 inch is 500 miles, then 4 inches is how many miles?
tiny-mole [99]

Answer:

2,000 miles

Step-by-step explanation:

We are given:

1 inch=500 miles

This can be rewritten as:

\frac{500 miles}{1inch}

This is representative of a unit rate, as we have a 1 in the denominator. To calculate the number of miles in 4 inches, simply multiply the unit rate by 4:

\frac{500 miles}{1inch}*4=

\frac{2000 miles}{4 inches}

This can rewritten as:

4inches=2000miles

Therefore, there are 2,000 miles in 4 inches.

-

We can check our solution by simplifying the fraction \frac{2000 miles}{4 inches} by dividing both 2000 and 4 by 4 to see if we achieve the unit rate:

\frac{500 miles}{1 inch}

Since this is in fact the unit rate, our solution is correct!
