Which best describes how to solve the equation for x.
prohojiy [21]

Answer:

B. multiply both sides by c.

Step-by-step explanation:

To solve the equation for x, you have to isolate the x variable on one side of the equation. To do this, do the opposite of any operation applied to x to remove other variables from the x's side of the equation:

x/c = d

multiply both sides of the equation by c to isolate x:

(x/c) * c = d * c

x = dc

Now x can be solved for.

Hope this helps :)

Use the law of cosines to write an expression equivalent to b
andrezito [222]

Given:

A triangle ABC.

The given expression for b is:

b=\sqrt{m+n-pq}

To find:

The expression that is equivalent to b.

Solution:

According to the Law of Cosines,

b^2=a^2+c^2-2ac\cos B

It can be written as:

b=\sqrt{a^2+c^2-2ac\cos B}              ...(i)

We have,

b=\sqrt{m+n-pq}                                ...(ii)

On comparing (i) and (ii), we get

m=a^2

n=c^2

p=2ac

q=\cos B

Therefore, the required values are m=a^2,n=c^2,p=2ac,q=\cos B.

Which statement can be combined with its converse to form a true biconditional?
andrey2020 [161]

Answer:

D)

I couldn't read C. It contained words like rat, raid devices?

Step-by-step explanation:

The converse of p->q is q->q.

So let's look at each choice:

A) The converse of

"if the measure of an angle is 30, then it is an acute angle"

is:

"If is is an acute angle, then the measure is 30"

The converse is not true so the biconditional will not be true.  There are other angles beside 30 that are acute.

B) The converse of

"if two lines intersect, then the two lines are not skew"

is:

"If the two lines are not skew, then the two lines intersect"

The converse is false because if it isn't skewed, then they could still be parallel and parallel lines don't intersect.

D) The converse of

"if an angle is a straight angle, then it’s sides are opposite rays.:

is:

"If the angle's sides are opposite rays, then it's angle is straight"

True.

So the biconditional is

"an angle is straight, if and only if, the angle's sides are opposite rays.
