Rename as a mixed number in simplest form. 15 22/20

Answers

16 1/10
Because you have 15 and then for 22/20 it is a improper fraction so take 20 away from it to get 2/10 then add 1 to 15 for 16 and then simplify 2/20 to 1/10

Answer:

The answer is: 1 2/20

Step-by-step explanation:

All you need to do is divide 22/20. I did long division, but you may use a calculator. When you divide 22/20, you should get 1. Now, you multiply 1x20 and you get 20 because anything multiplied with 1 is its self. Once you do that, you will subtract  22-20, and you will get 2. You will keep the denominator the same and your answer will be 1 2/20.

Step-by-step explanation:

A rectangle has a length that is unknown but is 12 inches longer than its width, w. The perimeter of the rectangle is 104 inches.
(a) Write an expression for the length of the rectangle in terms of w. Label it on the diagram. (b) Write an equation using the perimeter to find the value of w. Solve it for w.

Answers

Answer:

[tex]2w+2(w+12)=P (104)[/tex] and [tex]w=20[/tex]

Step-by-step explanation:

We know that the following equation represents the problem:

[tex]2w+2(w+12)= P[/tex]

So this means that we can do this:

[tex]4w+24= P[/tex]

We know that [tex]P[/tex] is 104. We need to fix our current equation, giving us:

[tex]4w+24=104[/tex]

We can subtract 24 to give us [tex]w[/tex] as a standalone with a coefficient.

[tex]104-24=80[/tex]

[tex]4w=80[/tex]

Then, simply divide the answer by the coefficient to give us the answer of:

[tex]80/4=20\\[/tex]

[tex]w=20[/tex]

[tex]w[/tex] is 20.

I think the answer is 20

Reflect (-6, -7) across the x-axis. Then reflect the result across the y-axis. What are the coordinates of the final point? ​

Answers

The final coordinates will be (6, 7)

The coordinates of the final point are (6, 7).

What is a reflection?

There are two ways of reflection.

Along x-axis:

(x, y) – (x, -y)

Here we change the sign of the y-coordinate and keep the x-coordinate same.

Along y-axis:

(x, y) - (-x, y)

Here we change the sign of the x-coordinate and keep the y-coordinate same.

Example:

(4, 3) reflection along the x-axis is (4, -3).

(4, 3) reflection along the y-axis is (-4, 3).

We have,

(-6, -7)

We use these:

Along x-axis:

(x, y) – (x, -y)

Here we change the sign of the y-coordinate and keep the x-coordinate same.

This means,

(-6, -7) → (-6, 7)

Now,

Along y-axis:

(x, y) - (-x, y)

Here we change the sign of the x-coordinate and keep the y-coordinate same.

This means,

(-6, 7) → (6, 7)

Thus,

The coordinates of the final point are (6, 7).

Angles B and W are supplementary. Angle B has a measure of (4x+16)˚. Angle W has a measure of 68˚.

What is the value of x?

Answers

the answer is 24 . 180-68= 112 then you -16 soo it would be 96. then you divide by 4 soo 96/4 would be 24 .

Answer:

Step-by-step explanation:

first, set angle b+w=180. You do this because both of the angles added together equals 180°.

Second, begin to isolate the variable.    4x+16 +68= 180

                                                                  4x = 96
