Answer:

k=7

Step-by-step explanation:

Call me weird but I love these types of questions.

Ok to solve this here's what you need to do.

Your solving for k right?

So make an equation.

Product is the result of multiplication so 12 and k would be 12k.

It needs to equal 84 so 12k=84

Now you need to get rid of 12.

You need to use the opposite operation as the number your trying to get rid of. In this case it would be division.

[you do not divide the x because you need it alone on one side]

So 12k divided by 12 = 84 divided by 12

12k/12 is k because a number divided by itself is 1.

84/12 is 7.

that leaves us with k=7

Thats it!

Answer:

B. equivalent

Step-by-step explanation:

Our two equations are:

y=-\frac{1}{3} x +\frac{2}{3}

2x+6y=4

Let's use substitution and plug in the expression -\frac{1}{3} x +\frac{2}{3} for y in the second equation. That way, we're getting rid of a variable so we can solve for the other:

2x+6y=4

2x+6(-\frac{1}{3} x +\frac{2}{3})=4

2x-2x+4=4

4=4

0=0

This means that there are an infinite number of solutions possible for this system - any x value will work. So, the answer is equivalent, because these two equations are essentially the same.

Find sin A, round to the nearest hundredth.
almond37 [142]

Answer:

.92

Step-by-step explanation:

sin A = opp side/ hypotenuse

       

We can use the Pythagorean theorem to find the hypotenuse

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

3^2 +7^2 = AC ^2

9+49 = AC ^2

58 = AC^2

Taking the square root

sqrt(58) = hypotenuse

sin A = 7/sqrt(58)

sin A =.91914503

sin A = .92
