-2 because in the second equation it is : 2x. If you multiply x in the first equation by -2 it will cancel out 2x in the second equation. -2x cancels out 2x. -2x+2x=0

Almost 9 over 16 of the total water supplied to a household is used for taking showers. Determine the decimal equivalent of 9 ov
NeX [460]

Answer:9/16 equals to 0.5625 so it terminates.

16 doesn't go into 9 so 0. Add a zero so 16 goes into 90 5 times and it equals to 80 so subtract 80 from 90 which equals 10.  Add another zero since 16 cant go into ten and 16 goes into 100 6 times and it equals to 96 so 100-96 equals 4. Sixteen cant go into 4 so add a zero which makes it 40. 16 goes into 40 2 times and it equals to 32 so 40-32=8. Add a zero to the eight and 16 goes into 80 5 times and etc etc.

Mark Brainliest please


Answer: 10 years

Explanation:


The original cost of the machine = 20000

The scrap value of the machine = 13122

Value of the machine = ( 20000 - 13122 ) = 6878

Depreciation of the machine for the first year = ( 6878 * 10 % )
= 687.8
So, the effective life of the machine is = ( 6878 / 687.8 )
= 10 years

Evaluate 6x for each value of x. x = 2/3
Leviafan [203]
You have only listed one value for 'x'.

If 'x' is 2/3, then  6x  is (6 times 2/3).  That's  12/3  or  <em>4 .</em>
