half a number
Twice the rational number 5/2 = 5From this, you need to subtract 4 3/5 to get 2/5.
means divide the number by 35, then double it
The additive opposite of a positive is a negative, and the opposite of a negative is a positive. If you reverse the sign twice (opposite of opposite) you have the original number. The same applies to an inverse (multiplicative opposite): the inverse of any inverse for a nonzero number is the original number. n (1/n)(n) = n
Meiosis divides twice since it is trying to duplicate the cells to create two new daughter cells for the creation process in species. It is the opposite of mitosis.
11, you can write the question in the form of x=-2x+33, then add 2x to both sides to get 3x=33, now divide both sides by 3 and you get x=11.
if you have the area. divide the area by the length to get the width. If you have the perimeter subtract the length twice and divide the number you have by two. If it is a square the width is the same as the length.
if the product of a number and -7 is reduced by 3, the result is 33 less than twice the opposite of the number. What is the number?
Twice the number n is 2n.
move the decimal over twice
