Answer: 20.7

Step-by-step explanation:

Step 1. Ok, to round to the nearest 10th means to round to the nearest 10th place on the decimal side of the of the number.

Step 2. The 10th place in this decimal 10.73 is where the 7 is.

Step 3. If the 100th place is less than 5 you round down. Since, the hundredth place in this decimal is where the 3 is you are going to round down.

The answer is 20.7. Hope this helps!

X/4 - y/3 =1 X and Y axis standard form

Semenov [28]

Answer:

Step-by-step explanation:

x/4 - y/3 = 1..multiply everything by the LCD....which is 12

3x - 4y = 12 <== standard form

=====================================

if it makes it easier for u, x/4 is the same as (1/4)x and y/3 is the same as (1/3)y

so ur problem can be written as : (1/4)x - (1/3)y = 1....multiply by 12

12(1/4)x - 12(1/3)y = 12(1)

(12/4)x - (12/3)y = 12.....reduce

3x - 4y = 12
