Write and solve an equation that represents the following: Thirty less than a number is equal to twelve.

42-30=12

Step-by-step explanation:

add 30 and 12 because then you get the total that will let you subtract the 30 to get your answer of 12 which your equation is 42-30 equals 12

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
