Zack used these steps to solve this equation: Three-fourths y + 5 = negative three-fourths y minus 9. Step 1: StartFraction 6 Ov

er 4 EndFraction y + 5 = negative 9. Step 2: StartFraction 6 Over 4 EndFraction y = negative 14. Step 3: (StartFraction 6 Over 4 EndFraction) StartFraction 6 Over 4 EndFraction y = negative 14 (StartFraction 6 Over 4 EndFraction). Step 4: y = negative 21. When Zack checked his solution, it didn’t work. What was his mistake? In step 1, he should have used the multiplication property of equality. In step 2, he should have a constant of – 4 on the right side. In step 3, he should have divided both sides by StartFraction 6 Over 4 Endfraction. In step 4, the answer should be positive.

A submarine is running at a depth of 235 ft underwater. It changes course and rises 101 ft. What is the change in elevation?
Bumek [7]

Answer:

The change in elevation is -134 ft

Step-by-step explanation:

Given;

initial depth of the submarine, d₁ = 235 ft

final depth of the submarine, d₂ = 101 ft

The change in the elevation of the submarine is given by;

Δd = d₂ - d₁

Δd = 101 ft - 235 ft

Δd = -134 ft

The change in elevation is negative because the submarine is moving closer to the surface.

Therefore, the change in elevation is -134 ft
