Houston has been hired as a salesman. he is paid a flat rate of $515 each week and earns an additional $17.50 commission for each sale. if x represents the number of sales and y represents the total earn, which equation will houston determine the amount he earns in one week? a.) y = $515h - $17.50 b.) y = $17.50h - $515 c.) y = $515h + $17.50 d.) y = $17.50h + $515

need more information

step-by-step explanation:

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

uhhh idk u yolo?

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
