The solution of the expression is -1 ⇒ 3rd answer
Step-by-step explanation:
Let us revise some important rules on the number line
- If we add number to another number we move to right
- If we subtract a number from another number we move to left
∵ The expression is negative 2 minus 3 minus (negative 4)
∵ negative 2 = (-2)
∵ minus means (-)
(-2) minus 3 means move 3 units from (-2) to left, so you will pass -3, -4, and stop at -5
∴ (-2) - 3 = -5
∵ minus (negative 4) = - (-4)
- Remember (-)(-) = (+)
∴ minus (negative 4) = + 4
That means move 4 units to the right from -5, then you will pass -4, -3, -2, and stop at -1
∴ -5 + 4 = -1
∴ The expression (-2) - 3 - (-4) = -1
The solution of the expression is -1

Answer: B: 140.4
Step-by-step explanation:
Hello!
Since ΔEFG is congruent to ΔJKL, their corresponding angles are congruent (CPCTC). The congruence statement tells you which angles of the triangle correspond; ∠E corresponds to ∠J, ∠F corresponds to ∠K, and ∠G corresponds to ∠L. The measures of all the angles of ΔJKL are given, so you just have to name the angle of ΔJKL that corresponds to ∠E of ΔEFG.
Looking at the congruence statement, ∠J corresponds to ∠E, and the m∠J is 90°. Thus the answer is 90°.
Answer:
m∠E = 90°
The cubic meters of water did the hull of the titanic have to displace to stay afloat is known to be about 52,310 tons that is 51843.918 m³ of water.
<h3>What is the titanic calculations about?</h3>
The RMS Titanic is known to be a ship that is said to be owned by the White Star Line.
This is known to be the biggest British passenger liner that was said to have sank when it was on its maiden voyage in the year 1912 in the North Atlantic Ocean.
Note that it sank because it was said to have hit an iceberg on Sunday, 14 April 1912.
The Titanic was said to be about 46,328 gross register tons and was known to have displaced about 52,310 tons of water.
So, 1 ton (displacement) ≈ 0.99109 cubic meters (m³)
Therefore, 52,310 tons
= 52,310 × 0.99109 m³
≈ 51843.918 m³
Therefore, The cubic meters of water did the hull of the titanic have to displace to stay afloat is known to be about 52,310 tons that is 51843.918 m³ of water.
