Answer:20mph
Step-by-step explanation:
speed of plane = x mph
Speed of plane with wind = 485 mph
So therefore, speed of wind =
485 - x
Speed of plane against wind = 445 mph
So therefore, speed of wind =
x - 445
So therefore, equating the 2 equations of speed of wind
485 - x = x - 445
Collect like terms
485 + 445 = x + x
930 = 2x
2x = 930
x = 930/2 = 465 mph
Speed of wind = x = 465mph
So we put this value on any of the equations for speed of wind
Speed of wind = x - 445 = 465 - 445
= 20 mph
So therefore, speed of wind = 20mph
Answer:
add them up
Step-by-step explanation:
add 8 10 10 and 80 25 20
your answer is
W<5.
the graphic will be like my drawing I hope you understand it because it is difficult to draw here
I’m sorry but I don’t know i would honestly like to help u but don’t know
Y= 3x - 10
<span>3x + 2y = 16
3x+2(3x-10)=16
3x+6x-20=16
9x-20=16
9x=36
x=4
y=3x-10
y=3(4)-10
y=12-10
y=2</span>
