What is the difference between the number of solutions for a two-step equation and for a two-step inequality

Sophie [7]

Answer:

A two-step equation is something like:

A*X + B = C

In this case, like in a linear equation, we have only one solution that can be found as:

A*X = C - B

X = (C - B)/A

In the case of a two-step inequality, we have something like:

A*X + B > C

Solving this we get;

A*X > C - B

X > (C - B)/A

In this case, any value of X that is larger than (C - B)/A is a solution, so in this case, we have infinite solutions.

That is the difference between the number of solutions for each case, in a two-step equation we have only one, while in the case of the inequality we have infinite.

Which one is it? Plz help

Multiplication and division with the powers of ten

So, when multiply powers of ten, all you have to do add up the powers.

The reverse goes when you are dividing. You would subtract the powers.

9 x 10^7 => 3 x 10^3

The words " how many times as large as " indicates that we are going to divide the two, making it look like this:

$\frac{(9)(10^{7}) }{(3)(10^{3}) }$

Divide the 9 by 3 you get 3

Then subtract 10^3 from 10^7

Therefore, the answer is 3 x 10^4, or A

Solve the right triangle. round your answers to the nearest tenth. help.

hammer [34]

Answer:

19.2

Step-by-step explanation:

Cosine rule :

$\sqrt{a^{2} +b^{2} ﹣2abcos(angle ) }$

c will always be the hypotenuse.

a and b can be any if the opposite or the adjacent.

${15}^{2} + 12^{2} - 2 \times 15 \times 12 \times \cos(90) = 369$

\sqrt{369}=19.20937...

Find the measure of <3

sattari [20]

Keeping in mind that, a circle has a total of 360°, so if we split it in 6 equal angles with that hexagon, we'll end up with 60° angles, and with 6 equilateral triangles.

check the picture below.
