Answer:

Nearly [too low]

Step-by-step explanation:

*<em>Twelve</em><em> </em>→ dozen

<em>Twenty-four</em><em> </em>→ 2 dozen

(24)(4) = 96

Add this to 97 to get 193.

196 > 193

This is a little too low. Choose the third option though.

I am joyous to assist you anytime.

Two equations for the constant of proportionality equal to 1/2
NemiM [27]

y=kx and y=\frac{k}{x} are two equations of constant of proportionality

Step-by-step explanation:

          There are two equations for the constant of proportionality. That is

                       (i) Direct proportion

                       (ii) Inverse proportion

          In direct proportion y=kx, Now

                  if x increases, then y also increases and if x decreases, then y also decreases. So, k is a constant proportionality.

         In Inverse proportion y=\frac{k}{x}, Now

                 if x increases then y decreases and if x decreases, then y increases and k is a constant proportionality.

         In direct proportion, we put y=1 and x=2, So k=\frac{1}{2}.

         So, the equations y=kx and y=\frac{k}{x} are two equations of constant of proportionality.

Write the expression for the perimeter of the rectangle
Sergeu [11.5K]

Answer:

perimeter = 2(x + 5)

this is 2x + 10

x = 55 inches

Step-by-step explanation:

this question is a bit weird because they didn't put the units for 5, so I'm assuming it's in inches...

the perimeter of a rectangle will have two of each, so we can put the 2 outside the bracket since it applies to everything. We have x and we have 5 so put those in the bracket with a plus sign because you add when you're calculating the perimeter.

5 + 5 = 10

120 - 10 = 110 inches (this is 2x)

110 ÷ 2 = 55 inches
