Answer:

Step 1

Step-by-step explanation:

Correct solution step-by-step:

1. 5(x + 2) = 6x + 12

2. 5x + 10 = 6x + 12

3. 5x - 6x = 12 - 10

4. -x = 2

5. x = -2

HELP PLEASEEE. I DONT UNDERSTAND

Shtirlitz [24]

Answer:

D

Step-by-step explanation:

So we have the equation:

$x^2-6x+58=0$

And we want to solve for x.

We can solve it by completing the square.

First, subtract 58 from both sides:

$x^2-6x=-58$

Divide the b term by 2 and square it:

$(-6)/2=-3\\(-3)^2=9$

So, add 9 to both sides:

$(x^2-6x+9)=-58+9$

On the left, the perfect square trinomial pattern. Add on the right. So:

$(x-3)^2=-49$

Take the square root of both sides:

$x-3=\pm \sqrt{-49}$

The square root of -49 is 7i:

$x-3=\pm 7i$

Add 3 to both sides:

$x=3\pm 7i$

So, our answer is D.

And we're done!

Given: If x, then not y, if not y, then z.<br> Y is true. So:

Fed [463]

If x, then not y, if not y, then z. Y is true. So: X is true, Z is True

<h3>How to Interpret Conditional Statements?</h3>

A conditional statement is a type of structure to express the relationship between two dependent variables. Its structure is as follows:

If P, then Q...

Now, from the question we are told that;

If x, then not y, if not y, then z.

Y is true. So:

Now, when looking at conditional statements in depth, and comparing to this question we can easily see that since Y is true, then it means that if X is true, then Z is also true.

Thus,

If x, then not y, if not y, then z.

Y is true. So: X is true, Z is True

A mountain bike has a diameter of 26 inches. To the nearest foot how far does the tire travel when it makes 32 revolutions?

Tcecarenko [31]

Hello!

You have to find the circumference

You use the equation

$2 \pi r$

r is radius which is half the diameter

This gives us 81.68

Multiply this by 32

81.68 * 32 = 2613.76

This is 217.8133333 feet

The answer is 217.8133 feet

Hope this helps!
