3 1/2 = 7/2 miles ... 3/4 hour = 3/4 * 60 minutes = 45 minutes
x miles = ? ... 1 minute
y miles = ? ... 1 hour

If you would like to know the number of miles in 1 minute or the number of miles in 1 hour, you can calculate this using the following steps:

7/2 * 1 = 3/4 * y
7/2 = 3/4 * y /*4/3
y = 7/2 * 4/3
y = 14/3 = 4 2/3 miles (per one hour)

7/2 * 1 = 45 * x
7/2 = 45 * x /45
x = 7/2 / 45
x = 7/90 miles (per one minute)

Answer:

y = 20

Step-by-step explanation:

$9 - \sqrt{y - 4} = 5$

<h3>i) move 9 to the right-hand side and change its sign</h3>

$- \sqrt{y - 4} = 5 - 9$

<h3>ii) calculate the difference</h3>

$- \sqrt{ y - 4} = - 4$

<h3>iii) change the signs on both sides of the equation</h3>

$\sqrt{y - 4} = 4$

<h3>iv) square both sides of the equation</h3>

$( \sqrt{y - 4} ) {}^{2} = 4 {}^{2}$

$y - 4 = 4 {}^{2}$

$y - 4 = 16$

<h3>v) move -4 to the right-hand side and change its sign</h3>

$y = 16 + 4$

<h3>vi) add the numbers</h3>

$y = 20$
