You go to a store and have a total of $300 to spend. You see a sign in the store that advertises all jeans are $40 and all shirts are $10. You want to take home 6 items of clothing. Which pair of equations can be used to determine j and s, if j represents the number of jeans you want to buy and s represents the number of shirts you want to buy?

You will buy 8 jeans and two shirts.

Step-by-step explanation:

set up a systems of equations

identify your variables

jeans = j (a variable means like 'x')

shirts = s

identify a common way to eliminate a variable

(get a common value in both equations so you can add or subtract to leave on variable in which you can solve for)

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.
