Answer:
(x, y) = (-3 5/8, 1 5/16)
Step-by-step explanation:
Add y+14 to the second equation to get ...
3.5x +14 = y
Substitute this for y in the first equation:
2.5x -3(3.5x +14) = -13
2.5x -10.5x -42 = -13
-8x = 29
x = -29/8 = -3 5/8
Using this in the formula for y, we get ...
3.5(-29/8) +14 = y
-203/16 +14 = y = 21/16 = 1 5/16
Answer:
57/40
Step-by-step explanation:
Find common denominators, note that what you do to the denominator, you must do to the numerator:

First, multiply 5/8 with 5 to both the numerator and denominator:
(5/8) x (5/5) = 25/40
Next, multiply 4/5 with 8 to both the numerator and denominator:
(4/5) x (8/8) = 32/40
Combine the numerators:
(25 + 32)/40 = (57)/40
57/40 is your answer.

Answer:
17.6 miles
Step-by-step explanation:
5 divided by 8 is 1.6
1.6 times 11 is 17.6
1 = 90
2 = 65
3 = 65
4 = 25
90+25=115
180-115=65
