2. Martha bought a total of 12 items from the book store. Each item was either a pack of pencils of $1.25 or a spiral notebook for $3.50. She spent a total of $37.50. How many packs of pencils did she buy?​

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

(x) - (y) = (1 + 4i)

the answer is

d.

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
