Twice a number would be written as 2x.
If the number is represented by variable x, then twice the number is represented by 2x.
An odd number squared would always equal an odd number and an even number squared would always equal an even
You would need to divide by -1/2.
The number that multiplied by 32 would equal 81 is 2.53125.
Twice a number would be written as 2x.
If the number is represented by variable x, then twice the number is represented by 2x.
That depends on the value of the whole. For example 95 would be 95% of 100. If the whole is 200, it would be twice that, etc. To find 95% of any number multiply it by 95% to get the answer.
Assuming the hydrocarbon is saturated the formula would be C21H44 In a saturated hydrocarbon the number of hydrogen atoms is equal to twice the number of carbon atoms, plus two.
Raising large number of cattle
Let's call "a number" x. Twice that number would be 2x, and then add 27, so the expression would be 2x + 27.
That would be 11.
998,949 If the tens place was any other number, it would either be smaller then 4 x 2 = 8, or it would equal more then 10 in the thousands place.
An odd number squared would always equal an odd number and an even number squared would always equal an even
If the number is 'z', then five less than twice the number is ( 2z - 5 ).
It is a whole number which would equal 1 or more
You would need to divide by -1/2.
