Y and x have a proportional relationship and y=9 when x=2 what is the value of y when x=3

Mathematics

Paladinen [302]3 years ago

If they are proportional, then y/x should always be the same.

So 9/2= 4.5

We need to find the y value at x=3 to make y/x equal 4.5

4.5 = y/3

y = 4.5*3 = 13.5

The perimeter of a rectangle is 182 ft. The width is two more feet than the length . Find the length and width.
Kamila [148]

Let's call the width w and the length l based on this, we can make two equations based on the first and second sentences in the problem.

w = l + 2

2l + 2w = 182


If we substitute l + 2 for w into the second equation, we can make the following:

2l + 2(l + 2) = 182

  • Substitute

2l + 2l + 4 = 182

  • Use the Distributive Property

4l + 4 = 182

  • Combine like terms

4l = 178

  • Subtract 4 from both sides

l = \dfrac{178}{4} = \dfrac{89}{2}

  • Divide both sides by 4 and simplify

Now, let's find w:

w = l + 2 = \dfrac{89}{2} + 2 = \dfrac{93}{2}


The length of the rectangle is \boxed{\dfrac{89}{2} \,\textrm{ft}} and the width of the rectangle is \boxed{\dfrac{93}{2} \,\textrm{ft}}.
