Answer:

r = 8

Step-by-step explanation:

I don't know the options But...

if r equals 8 and you plug in 8 for r in the equation which would look like

$\frac{8}{4}$ and that would equal 2.

$\frac{8}{4}$ = 2

Hope this helps.

x₁,₂= $\frac{1(+/-)\sqrt{25} }{6}$

x₁,₂= $\frac{1(+/-)5}{6}$

x1= $\frac{1+5}{6}$ =6/6=1

x2= $\frac{1-5}{6}$ = $\frac{-2}{3}$

x1=1

x2= $\frac{-2}{3}$

If an hour is 45 years how long is a minute

Ainat [17]

Since one hour = 45 years, one minute should be 1/60th of 45 years because 60 minutes = an hour.

45/60 = 3/4

So one minute would be 3/4 of an hour, or 45 minutes.

Hope this helps!
