For which equations is 8 a solution? Select the four correct answer

maxonik [38]

Answer:

I believe the answers are= 2, 3, 6, 8

Step-by-step explanation:

For #2, you would subtract 2 from both sides. 10-2=8. x=8.

For #3, you would add 4 to both sides of the equation, making the final answer: x=8

For #6, you would divide both sides by 3. 24 divided by three is 8.

For #8, I multiplied the whole equation by 8, which is the denominator of x/8. 1 times 8=8. The final answer would be x=8.

Hope this helps!

Identify variables

Angle θ = x

Opposite leg AC = 24

Adjacent leg CB = 35

Step 2: Solve for x

Substitute in variables [Tangent]: $\displaystyle tanx^\circ = \frac{24}{35}$
Inverse Trig [Tangent]: $\displaystyle x^\circ = tan^{-1}(\frac{24}{35})$
Evaluate: $\displaystyle x = 34.439^\circ$
Round: $\displaystyle x \approx 34^\circ$

A boat travels 12 Mph in still water. It can travel 18 miles upstream in the same time that it can travel 24 miles downstream. W

quester [9]

Answer:

The current of the water is 1.714 mph.

Step-by-step explanation:

Let the boat in t hours can travel 18 miles upstream, and 24 miles downstream.

Therefore, if the speed of the boat in still water is 12 mph and that of water is x mph , then we can write

$\frac{18}{t} = 12 - x$ ........ (1) and

$\frac{24}{t} = 12 + x$ ............ (2)

Now, adding those two equations (1) and (2) we get,

$\frac{18}{t} + \frac{24}{t} = 24$

⇒ t = 1.75 hours.

Now, from equation (1) we get

$\frac{18}{1.75} = 12 - x$

⇒ x = 1.714 mph

Therefore, the current of the water is 1.714 mph. (Answer)
