.4x=.5x-30 solve for x

x=300

Step-by-step explanation:

Multiply both sides by 10

0.4x·10=0.5x·10-30·10

Refine

4x=5x-300

Subtract 5x from both sides

4x-5x=5x-300-5x

Simplify

-x=-300

Divided both sides by -1

-x/-1=--300/-1

Simplify this and you will get x=300

Hope this Helps

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

add 5 subtract 1
