Assume that y varies inversely with x. If y=12 when x=5, find y when x=3

Inversely variation means xy = c, where c is a constant

Since when y = 12 x = 5, then c = 12*5 = 60

So xy = 60

Now when x = 3, y = 60/3 = 20

4-2x=11 how do I solve
Bingel [31]

Hey there!☺

Answer:\boxed{x=\frac{-7}{2}}

Explanation:

4-2x=11

In our first step, we will simplify both sides of the equation:

4+-2x=11\\-2x+4=11

Now subtract 4 from both sides:

-2x+4-4=11-4\\-2x=7

In our last step, we will divide both sides by -2:

\frac{-2x}{2}=\frac{7}{-2}\\  x=\frac{-7}{2}

x=-7/2 is your answer.

Hope this helps!☺

If you walked 5 miles down a trail and then walked 2 1/4 miles back, how many miles away are you from your starting point?
lyudmila [28]
First lets figure out 2 and 1/4 as a decimal 
2 and 1/4 = 2.25 
So now we subtract 
5 - 2.25 = 2.75 
She is 2.75 miles away from her starting point
