#4 me? ! ! what’s the solution set? 0.30(18)+0.05x=0.15(24+x)

The answer should be x= 18

Multiply the numbers

5.4+0.05x=0.15(24+x)

Move the variable to the left side c=and change the sign

5.4+0.05x-0.15x=3.0

collect terms

-0.1x=3.6+5.4

Divide both sides of the equation by -.01

x=18

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
