In the diagram below AC is parallel to rp:
How many units? please help!

15+21+81 . (im too lazy to solve that)

Step-by-step explanation:

comparing the smaller and larger triangle, (line a-b) . 14 is 2x more than 7. Based on that, (line c-b)  10 is 2x more than 5, which is the missing side(p-b). If you add 18+21+15,   your answer

3

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!
