The Foxy Lady Shop is having a summer closeout sale. A pair of jeans cost $20 and a t-shirt costs $9. If you spend $172 and buy a total of 13 items, how many pairs of jeans and t-shirts
can you purchase? ?

I need this to be solved using a matrix

grab rope, tie a loop-de-loop, put it around ur neck, now jump while its tied to a high place. now your shoes are cool.

step-by-step explanation:

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

brainliest? ?

here try this one

3a-24=0

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.
