The equation representing when the two planes would be at the same altitude is 9x=486
<h3>In terms of mathematics, what is an equation?</h3>
Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.
From (a) we get that: Altitude of Plane A = 990-18x
Altitude of Plane B = 1476-27x
make 890 - 18x = 1476-27x
-18x+27 x = 1476-890
9x=486
X= 54
so pass 54 seconds will the two plane at the same altitude.

Answer:
293 seconds
Step-by-step explanation:
60*4=240
240+53=293
The price per cubic inch for the extra large tub will probably be 2000
Answer:
<h3>20.6 ft</h3>
Step-by-step explanation:
You must use the trigonometric function.
In this case, it will be tangent.
We have
Substitute:
<em>multiply both sides by 20</em>
Tree height is r + 5.
Therefore
Step-by-step explanation:
by comparing both f (x) and g (x)
we get
3x-1=2x-1/x
by this way we can get the value of X and put the value of X in f (x) and g (x)
