Step-by-step explanation:
Answer:
1). 24
2). 8
Explanation:
1).
285$ - 45$ = 240$
240$/10 = 24$
Therefore, he pays 24$ a month.
2).
Let x be the number than triple:
3x - 5 = 19
3x = 19 + 5
3x = 24
x = 24/3
x = 8
the answer to this problem is 1,940
Answer:
Plane speed x mph
wind speed 20 mph
against wind x - 20 mph
with wind x + 20 mph
Distance against wind 140
Distance with wind 160
Time = same equate the time against with time with current
t=d/r
140 /(x- 20 )= 160 /(x+ 20 )
140 *(x+ 20 )= 160 *(x- 20 )
140 x + 2800 = 160 x -3200
140 x -160 x = -3200 + -2800
-20 x = -6000
/ -20
x= 300 mph
