Mr jb has a rectangular lot that measure 550 meters by 0.75 km.What is the area of the land in square meter. He is selling the w
Art [367]

Answer:

The area in square meter is 412,500 square meters

the price per square meter is 500 pesos per square meter

Step-by-step explanation:

Firstly, let us get the measure of the dimensions in meters

Mathematically, 1000 m = 1 km

Thus;

0.75 km = 0.75 * 1000 = 750 m

The area of a rectangle is the product of its side lengths

mathematically, we have this as;

550 * 750 = 412,500 square meters

To get the price per square meter, we have to divide the price of the whole plot by the area

So we have ;

(206,250,000) pesos / 412,500 square meters

= 500 pesos per square meter

Solve -2/3x &gt; 8 or -x &lt; 4.
horrorfan [7]

Answer:

<u>x < -12</u>

Step-by-step explanation:

-2/3x > 8

-2/3x * (-3/2) < (-3/2)

cancel the common factor of 2

-x/3*-3<8* (-3/2)

Multiply

x<8 * (-3/2)

Simplify

x < 4 * -3

Multiply

x<-12

-2/3x > 8

= x < -12
