There are a few different ways to go about it.
I would do it like this:

(n - 5)/2 = 5

Multiply each side of the equation by 2 : n - 5 = 10

Add 5 to each side of the equation: n = 15

(n-5)/2=5 (Multiply terms on both sides of the equation by 2)

n-5=10 (Add 5 to both sides of equation)

n=10+5

n=15

A team of scientists is traveling by boat to study a pod, or group, of dolphins. The equation y = 0.2x can be used to find the d

Alenkinab [10]

Answer:

42 minutes.

Step-by-step explanation:

We know that:

y = 0.2*x

is the equation that that defines the distance, in miles, that the boat travels in x minutes.

We know that the dolphins are at 8.4 miles from the boat.

Then when we have y = 8.4, this will mean that the boat reached the dolphins.

Then we need to solve the equation:

y = 8.4 = 0.2*x

for x

To do that, we just need to isolate x in one side of the equation, so we can just divide both sides by 0.2 to get:

8.4/0.2 = (0.2*x)/0.2

42 = x

And x is time in minutes, thus, the boat needs to travel for 42 minutes to reach the dolphins.

One Fence Per Yard = $1.75

$73.50 - $3.50 (The Tax) = $70

$70 Divided by $1.75 = 40 Yards
