Answer:

Final position of scuba diver = 7 feet below the surface.

Explanation;

 Let us take down direction as positive and up direction as negative.

 A scuba diver dives down 15 feet into the ocean, position of scuba diver = +15 feet.

 He then swims 8 feet back up towards the surface, position of scuba diver = -8 feet

 Overall position = 15 - 8 = 7 feet.

 So final position of scuba diver = 7 feet below the surface.

Given x : y: z = 5:1:3 and z - y = 28. find the value of x + y​
Vera_Pavlovna [14]

Answer:

x + y = 84

Step-by-step explanation:

Given

x : y : z = 5 : 1 : 3, then

\frac{x}{y} = 5 ( multiply both sides by y )

x = 5y ←

and \frac{y}{z} = \frac{1}{3} ( cross- multiply )

3y = z

Substitute z = 3y into z - y = 28

3y - y = 28

2y = 28 ( divide both sides by 2 )

y = 14 ← ←

Substitute y = 14 into x = 5y

x = 5 × 14 = 70 ← ←

Substitute y = 14 into z - y = 28

z - 14 = 28 ( add 14 to both sides )

z = 42 ← ←

Thus x = 70, y = 14 and z = 42

Hence x + y = 70 + 14 = 84
