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:
6x + 2 ( x - 4) = 8 + 4 ( x + 2)
6x + 2x - 8 = 8 + 4x + 8
<em><u>Arranging</u></em><em><u> </u></em><em><u>like</u></em><em><u> </u></em><em><u>terms</u></em><em><u> </u></em>
6x + 2x - 4x = 8 +8 - 8
8x - 4x = 8
4x = 8
x = 8/4
x = 2

29/61
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The additive inverse property states that if we have a number a, then:
Here, we have the equation:
And we divide both sides by 2:
To acquire:
So, we did <em>not</em> use the additive inverse property since we didn't add anything.
Instead, we used the<em> division property of equality</em> by dividing both sides by 2.
So, our answer is A.
And we're done!
Answer:
b) It is a binomial with a degree of 3.
Step-by-step explanation:
We need to find about which is true about the polynomial –8m3 + 11m from the given choices.
There are two terms so it is binomial.
Highest exponent on variable m is 3 so degree is 3.
Correct matching choice is "It is a binomial with a degree of 3."
Hence final answer is choice "b) It is a binomial with a degree of 3."
