anygoal [31]

Answer: 163/27

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x + -1/9 = 18

Step 2: Add 1/9 to both sides.

3x + -1/9 + 1/9 + = 18 + 1/9

3x = 163/9

Suppose you are asked to find the area of a rectangle that is 2.1-cmcm wide by 5.6-cmcm long. Your calculator answer would be 11
Jlenok [28]

Answer:

12 square cm correct to 2 significant figures

Step-by-step explanation:

Area of a Rectangle = L X B = 2.1 X 5.6 = 11.76 square cm

To round your result to 2 significant figure, we start counting from the left from the first non-zero digit.

The first two digits are 11 but because the number after is 7 (greater than 4), we round up to 12.

11.76 square cm = 12 square cm correct to 2 significant figures
