Try this solution:
rule: Distance=speed * time, where Distance=10216 (mi); t=8 (h) and speed=slower_jet + faster_jet (mi/h);
note, that faster_jet=slower_jet+65 (mi/h). Using these:
(slower_jet+65)*8=10216;
slower_jet=(10216-520)/16;
slower_jet=606 (mi/h);
faster_jet=606+65=671 (mi/h).
answer: <u>606 & 671</u>
Answer: 873
Step-by-step explanation:
let age = x
x/3 - 76 = 215
x/3 = 291
x = 873
2) 1/16
3) 25/3 or 8 and 1/3
4) to find the reciprocal of 4 we must make 4 a fraction. Simply add a one as the denominator and then switch as you would usually do when finding the reciprocal.
4 = 4/1 = 1/4
Answer : 1/4
5) first, let's convert 4 5/8 into a improper fraction.
4 5/8 = 37/8
Now let's find the reciprocal of that number...
Answer : 8/37
6) 5/8 ÷ 2/3 does equal 15/16
To check, well do the inverse operation.
The opposite of division is multiplication.
Answer : d
7) 6
8) 13
Make two equations from the information. Then graph them and see where they intersect. The answer is 62 miles. Plug 62 back into both equations and they should both be the same number.
On day 15 you would have made 32,768 dollars, which surpasses the price of the car by 12,768 dollars
