How do you factorise 14x -21xy
Answers
Factor out the Greatest Common Factor (GCF), '7x'. 7x(2 + -3y)
Final result:
7x(2 + -3y)
that is the answer on how to do it
x(14-21y)
Hope it helped...

Water boils at different temperatures at different elevations. The boiling temperature of water is 212 degrees * F sea level (0 feet ) but drops about 1.72 degrees * F for every 1,000 feet of elevation. Write a formula for the boiling point at a given elevation. Then solve the formula for the elevation when the boiling point for water is 190 degrees F.

You can remove a zero from each dividend equal to the number of zeros in the divisor.
So 80,000 ÷ 2,000 is equivalent to 80 ÷ 2 = 40 ( I removed 3 zeros from each)
80,000 ÷ 200 is equivalent to 800 ÷ 2 = 400 (notice that I could only remove 2 zeros)
Finally 80,000 ÷ 20 only allows us to remove on zero --- 8,000 ÷ 2 = 4,000.
The smaller the divisor the greater the quotient (when dividing the same number - in this case 80,000)
Final answer:
The quotients of 80,000 divided by 2,000, 200, and 20 differ because of the magnitude of the divisor. The quotient is larger when the divisor is smaller.
Explanation:
The difference in the quotients of 80,000 divided by 2,000, 200, and 20 comes from the magnitude of the divider. The larger the divider, the smaller the quotient.
If you divide 80,000 by 2,000, the quotient is 40. When you divide 80,000 by 200, the quotient is 400. Lastly, if you divide 80,000 by 20, the quotient is 4,000. Hence, the quotients are different because of the different divisor values in each operation. The smaller the divisor, the larger the quotient gets.

The quantity of jelly beans bought by Mikayla is 3/8 pounds
What is a number line?
A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, represented by the symbol R." It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.
Given that a candy store sells different size bags of jelly beans. The line plot shows the weights of ten bags. Mikayla bought all of the. bags weighing less than 3/8 pound
The number of jelly beans will be calculated as,
1/4 = 2/8 ( 1/4 x 2/2 )
2/8 + 1/8 = 3/8 pounds

Well, I think we all worked with variables, but don't realise about it, because when people see these terms ''variable'', ''algebra'', they freak out.
The reality is that variables are everywhere, they are all those stuff that can variate: weigh, highness, money, population, interests, and so on.
A common problem I solved using variables is measuring time. For example, when I'm going to school I tend to calculate the time of my way.
