Three houses are mapped on a coordinate grid. Josh’s house is located on Red Street at (–5,–4).
Sarah’s house is located on Green Street at (2,5).
Emma’s house is located on the corner of Red Street and Green Street at (4,–1).
What is the measure of the angle (in degrees) where Red Street and the Green Street intersect?

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!

answer: no, but if it does it's a obvious pattern.
