Answer both questions for 20 points! you : )

4) cross multiply to get 3(2x - 6) = 6; multiply

6x - 18 = 6; add 18 to both sides

6x = 24; divide both sides by 6

x = 4

5) cross multiply to get 3(5x + 4) = 11x; multiply

15x + 12 = 11x; subtract 15x from both sides

12 = -4x; divide both sides by -4

-3 = x

I hope this helps!

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
