I have 5 blue pants and 6 pants with a zipper. If I have 9 pants that are either blue or have a zipper or both, how many pants a
sveta [45]

Answer:

2

Step-by-step explanation:

Blue pants: 5

Zipper pants: 6

total amount of pants (blue, zipper or both): 9

to find the pants that have both qualities, we need to find the difference between the total amount of pants and the sum of the blue and zipper pants:

sum of blue and zipper pants: 5 + 6 = 11

you can tell that there is a difference of

11 - 9 = 2 pants

this means that these 2 pants belong to both categories (blue and with a zipper). Thus there are 2 pants that are blue and have a zipper

Jack tossed a coin three times. Which tree diagram shows all the possible outcomes of the coin landing heads up or tails up? PLS
satela [25.4K]

Answer:

Solve this system of equations using substitution. Put your answer in ordered pair form, (x, y).3x + 2y = 2 -2x + y = 8
gregori [183]
-2x + y = 8
y = 2x + 8
now sub in 2x + 8 for y in the other equation
3x + 2y = 2
3x + 2(2x + 8) = 2...distribute the 2 thru the parenthesis
3x + 4x + 16 = 2
7x = 2 - 16
7x = - 14
x = -14/7
x = -2
now sub -2 in for x in either equation to find y
-2x + y = 8
-2(-2) + y = 8
4 + y = 8
y = 8 - 4
y = 4

solution is : (-2,4)
