Sarabeth is selling bracelets as a fundraiser for the school library. each bracelet with blue beads sells for $4.50. each bracelet with red beads sells for $5. she raised a total of $130 for the library. the number of bracelets with red beads (r) that sarabeth sold is 3 less than twice the number of bracelets with blue beads (b) sold. if the table is used to guess and check, what equation should go in the top of the third column?

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
