Answer:
3000 m
Step-by-step explanation:
Using Pythagoras theorem

Similarly

Length of the Tunnel = |AB|+|BC|
=1999.9+999.7
=2999.6
=3000 m

Step-by-step explanation:
9+6(2+3/6)
9+6(2+1/2)
2+1/2 = 2.5
9+6(2.5)
9+15

Answer:
The correct answer is: C
Step-by-step explanation:
2(4x - 5) < 14x + 8
First multiply 2 by 4x and -5
8x - 10 < 14x + 8
Now find out what x is
Move 14x to the left
8x - 14x - 10 = 8
Then move 10 to the right and change it's sign to plus
8x - 14x = 8 + 10
Now combine like terms
-6x = 18
Now divide 18 by 6 to get x
x = 18/-6
x = -3
I will solve your system by substitution.<span><span>x=<span>−2</span></span>;<span>y=<span><span><span>23</span>x</span>+3</span></span></span>Step: Solve<span>x=<span>−2</span></span>for x:Step: Substitute<span>−2</span>forxin<span><span>y=<span><span><span>23</span>x</span>+3</span></span>:</span><span>y=<span><span><span>23</span>x</span>+3</span></span><span>y=<span><span><span>23</span><span>(<span>−2</span>)</span></span>+3</span></span><span>y=<span>53</span></span>(Simplify both sides of the equation)
Answer:<span><span>x=<span>−<span><span>2<span> and </span></span>y</span></span></span>=<span>5/3
<span>
so the answer is B (the second choice)
