X = velocity of plane
y = velocity of wind
x - y = 1680/5 = 336 mph .....(1) [ plane flying against the wind]
&
x + y = 1680/4 = 420 mph....(2) [ plane flying with the wind]
Adding (1) and (2) to eliminate y gives
2x = 756
x = 378 mph is the speed of the plane with no wind.
T-m=25
3m=J
275=t+j+m

Answer:
x = 6 , 5. For these values of x they are equal.
Step-by-step explanation:
2x² - x + 55 =(x +5)²
2x² - x + 55 = x² + 2*x*5 + 5²
2x² - x + 55 = x² + 10x + 25
2x² - x + 55 - x² - 10x - 25 = 0
2x² - x² - x - 10x + 55 - 25 = 0
x² - 11x + 30 = 0
x² -6x - 5x + 30 = 0
x(x - 6) - 5(x - 6) = 0
(x - 6)(x - 5) = 0
x - 6 = 0 ; x - 5 = 0
x = 6 ; x = 5
Answer:
The slope is 2
Step-by-step explanation:
From the y-intercept which is 1, to get to the next point, you would go up 2 and 1 right which is 2/1, and 2/1 is technically just 2.
Hope this helps and pls do mark me brainliest if you can:)
Answer:
x = 5.2
Step-by-step explanation:
See the diagram first.
We know that in a triangle if we draw a line parallel to the baseline then it will divide the other two lines of the triangle in the same ratio.
Therefore, from the given figure it is clear that 
⇒ 3x = 26 - 2x
⇒ 5x = 26
⇒ x = 5.2 (Answer)
