Answer:
D) |−8,000 − (−50)|
Step-by-step explanation:
When we are dealing with questions involving above or below sea level,
The formula for the Absolute value expression representing the distance = | Height above sea level -(Distance below sea level|
Height of Cameron above sea level = 8000ft = -8000
Distance of the whale below sea level = 50ft = -50
Hence, we have:
|−8,000 − (−50)|.
Option D is the correct option
The solution of simultaneous equations is x=4 and y = -1.
<h3>What are
Simultaneous equations?</h3>
Simultaneous equations are two or more algebraic equations with the same unknown variables and the same value of the variables satisfies all such equations.
We can solve simultaneous equations by various methods. here we will solve it by elimination method.
Here we have two simultaneous equations
3x -2y = 14 --- (i)
and 4x + 3y = 13---(ii)
Now multiplying (i) by 3 and (ii) by 2 we get
9x -6y = 42 and 8x + 6y = 26.
Now adding both we get
17x = 68 ⇒ x = 68/17 ⇒ x = 4.
Substituting the value of x in (i), we get
3*4 - 2y = 14 ⇒ -2y = 14-12 = 2 = -2/2 ⇒ y = -1.
Therefore, the values of x and y are 4 and -1 respectively .
