Writing an Algebraic Expression with Parent White the expression. Then, check all that apply six times the sum of nine and a number Key Words Replace With Replace a number with the variable, n. The two operations are multiplication and addition The two operations are multiplication and subtraction The constants are 6 and 9. The expression is written as 6n +9. The expression is written as 6(9 + n). 6 SEX the sum of a numberHEL PLEASE ​

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
