Noah spent some of his allowance money on Monday. He spent 1/6 of his allowance on Tuesday and 3/6 of it on Friday. Noah has none of his allowance money left. What fraction of his allowance did he spend on Monday.

2/6 (also simplified to 1/3)

Step-by-step explanation:

1 + 3 = 4

6 - 4 = 2

divide 2 by 6 and you get 2/6

hopefully this helps ;)

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

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
