Step-by-step explanation:

Diameter of pizza = 12 inch

Therefore, radius r = 6 inch

Area \: of \: entire \: pizza \\  = \pi {r}^{2}  \\  = 3.14 \times  {6}^{2}  \\  = 3.14 \times 36 \\  = 113.04 \:  {inch}^{2}  \\  \\ amount \: of \: calories \: in \: entire \: pizza \\  = area \: of \: pizza \\  \times calories \: per \: square \: inch \\  = 113.04 \times 22 \\  = 2,486.88 \\

Two thirds of a number decreased by 27 is at least 9
Vitek1552 [10]

Answer:

The mathematical statement can be written as follows

\frac{2}{3}x-27\geq9

which has solution as

⇒  x\geq54

Step-by-step explanation:

Given:

Two thirds of a number decreased by 27 is at least 9.

This statement can be transformed into a mathematical statement.

Taking the unknown number as x and putting the inequality \geq9 as the result is at least 9.

So, we have

\frac{2}{3}x-27\geq9

Adding 27 both sides

\frac{2}{3}x-27+27\geq 9+27

\frac{2}{3}x\geq 36

Multiplying both sides by 3.

3\times\frac{2}{3}x\geq 36\times 3

2x\geq108

Dividing both sides by 2.

\frac{2x}{2}\geq\frac{108}{2}

∴ x\geq54
