A singer has 20 pairs of earrings, plus another 5 individual earrings which don’t have a match. One morning she reaches into her drawer without looking and pulls out a random earning. What is the probability that the earring she pulls out is part of a pair of earnings (and thus has a match)? Assume each earring has an equal chance of being pulled out of the drawer. Your answer should be a fraction in lowest terms.

40/45 8/9

Step-by-step explanation:

20 pairs= 40 individual

5 individual= 40+4=45 individual

45 individual and 45 in total=

40 over 45

simplify to make 8/9

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
