He must work about 4-5 more hours, and if he works 4 hours, he would earn $240, and $300 + $240 = $540. Or, if he works for 5 hours, it would equal $300. $300 + $300 IS $600, and his savings may be $60 or $100. Your Choice.

Answer:
first angle is 20, 2nd is 120, 3rd is 40.
Step-by-step explanation:
with these words, "20 less than a number, Three
times the number, is the number." We can set up the equation x-20+3x+x = 180. combine like terms and we get 5x-20=180. add 20 to both sides to get 5x=200 then divide 200 by 5x to get x = 40. We can then plug 40 into each of the expressions, x-20, 3x, x, to get our angles.
Answer:
a) 2 1/8 miles per hour
b) 8/17 hours per mile
Step-by-step explanation:
To find the rate in mile per hour, divide miles by hours:
(5 2/3 mi)/(2 2/3 h) = (17/3 mi)/(8/3 h) = 17/8 mi/h = 2 1/8 mi/h
__
To find the rate in hours per mile, invert that number:
1/(17/8 mi/h) = 1/((17 mi)/(8 h)) = (8 h)/(17 mi) = 8/17 h/mi
