Suzanne purchased tiles for her patio that are 8" and 4" . She measured her patio in metres and wants to convert the tile dimensions to SI units. What are the dimensions of tiles in centimetres

0.2 m, 0.1 m

20 cm, 10 cm

Step-by-step explanation:

as we know that

40 inch = 1 metre

So 1 inch = 1 /40 metre

So, the length of the tile = 8 inch = 8 / 40 metre = 0.2 metre

width of the tile = 4 inch = 4 / 40 = 0.1 metre

Now

1 metre = 100 cm

So, length of the tile = 0.2 m = 0.2 x 100 = 20 cm

width of the tile = 0.1 m = 0.1 x 100 = 10 cm  

stops on an even number.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
