Answer:
A if I'm not incorrect. Sorry if I am incorrect I'm bad at math.
Let the speed of the current be y and the speed of Micah's sailing speed be x. Then 4.48/(x + y) = 0.32
4.48/(x - y) = 0.56
0.32x + 0.32y = 4.48 . . . (1)
0.56x - 0.56y = 4.48 . . . (2)
(1) x 7 => 2.24x + 2.24y = 31.36 . . . (3)
(2) x 4 => 2.24x - 2.24y = 17.92 . . . (4)
(3) - (4) => 4.48y = 13.44
y = 3
From (1), 0.32x + 0.32(3) = 4.48
0.32x = 4.48 - 0.96 = 3.52
x = 3.52/0.32 = 11
Therefore, the speed of the current is 3 miles per hour.
Answer:
93
Step-by-step explanation:
Add 36 to both sides of the equation:
36 -36 + ___ = 36 +57
0 + ___ = 93
___ = 93
The integer 93 goes in the blank.
Answer:
x=1 y=14
multiply x-y=-13 by 3 so the x would cancel out. solve for y
then plug in y to one of the equations to get x
check your Unit Circle for those angles.
