Find X:<br><br> Solving Linear Equations With A Variable On Only One Side Of The Equation.
soldi70 [24.7K]

Answer:

x = 22 (see explanation!)

Step-by-step explanation:

Just with any algebraic equation, you will want to isolate the variable (x). Here's a step-by-step to show you how it's done:

1/7(x + 6) = 4

Multiply by 7 to get rid of the 1/7 (since 7 * 1/7 = 7/7 = 1)

7*1/7(x+6) = 7*4

x+6 = 28

Now, subtract 6 from both sides to isolate x:

x + 6 - 6 = 28 - 6

Finally:

x = 22

Deon has a pizza with a diameter
OverLord2011 [107]

The square box is enough to fit the pizza with a diameter of 10 inches inside. Since the area of the square box is more than the area of the pizza, the pizza fits easily in the square box.

<h3>What is the area of the circle and the square?</h3>

The area of the circle is

Ac = πr² = πd²/4 sq. units

Where r is the radius and d is the diameter of the circle.

The area of the square is given by

As = s² sq. units

Where s is the length of the side of a square.

<h3>Calculation:</h3>

It is given that a pizza(in a circular shape) with a diameter d = 10 in is to be placed in a square box of the same length as the diameter of the pizza.

So,

The area of pizza is

Ap = Ac = πd²/4 sq. units

     = π(10)²/4

     = 25π

     = 78.54 sq. in

Then, the area of the square box with the length same as the diameter of the pizza is,

As = d²

    = 10²

    = 100 sq. in

Since the area of the square is more than the area of the pizza (100 sq. inch > 78.54 sq. inch), the pizza easily fits into the square box.
