1. nick works two jobs to pay for college. he tutors for $15 per hour and also works as a bag boy for $8 per hour. due to his class and study schedule, nick is only able to work up to 20 hours per week but must earn at least $150 per week. if t represents the number of hours nick tutors and b represents the number of hours he works as a bag boy, which system of inequalities represents this scenario? t + b greater than or equal to 20 15t + 8b = 150 t + b less than or equal to 20 15t + 8b greater than or equal to 150 t + b less than or equal to 20 15t + 8b less than or equal to 150 none of the systems shown represent this scenario.

For the second question, the answer would be A because the lines intersect at 2 and -1.4. For the first question, t+b is less than or equal to 20 and 15b+8b is greater than or equal to 150 is the answer because Nick can work up to 20 hours and needs to make at least $150 per week so that answer fits best. That question is solved mostly by context clues.
Using Pythagorean theorem
9.5^2 + 18.9^2 = 90.25 + 357.21 = 447.46
√447.46 = 21.15
x = 21.15
