Find the value of x using the vertical angle theorem.
Please I really need help on this!

Answers

Answer 1

Answer:

x = 7

Step-by-step explanation:

x+16 = 4x-5

7+16=23

4x7=28-5=23

Vertical angle theorem states that angles vertically opposite to one another are equal

Answer 2
The vertical angle theorem says that angels across each other will equal the same value so using that logical we can start by setting the two angle value equal to each other and solve this we get x by itself.

x + 16 = 4x - 5
(Combine like terms with each other)

21 = 3x
(Divide by 3 on both sides of the equals sign to get x by itself)

x = 7


Hope this helps!!!

Answer:

10 sides (decagon)

Step-by-step explanation:

You find the perimeter by adding up all the sides of a shape.

side + side + side + side... = perimeter

You know that each side is 4/5 centimeters. You also know that the perimeter is 8 centimeters.

You can set up an equation like this:

4/5 * number of sides = 8

or you can write it in a simpler form as:

4/5x=8

Now solve it like a normal equation:

5 * (4/5x) = (8) * 5

(4x) / 4=(40) / 4

x = 10

So, you know the shape has 10 sides that are 4/5 centimeters each.

The answer is 10 sides

What is 19/20 as a decimal? Explain how you got your answer.

Answers

Answer:

0.95

Step-by-step explanation:

To make a fraction an exact decimal, you will need to divide it. 19 will be the dividend, and 20 will be the divisor (so you get an accurate decimal)

So when you divide, you will get 0.95.

Answer: 0.95

Step-by-step explanation: It's important to understand that decimals represent fractions with denominators of 10, 100, 1,000, 10,000, etc...

In order to write 19/20 as a decimal, we need to find a fraction

equivalent to 19/20 with a 100 in the denominator.

Notice that if we multiply the numerator and the denominator

of 19/20 by 5, we get the equivalent fraction 95/100.

Since the hundredths place is two places to the right of the

decimal point, we can write 95/100 as 0.95.

So 19/20 is equivalent to 0.95.

i need help 20 pts thx look at the image

Answers

Answer:

Factors are numbers you can multiply to get each number. For example, for 30 you would have factors of 1, 2, 3, 5, 6, 10, 15, and 30.  I got that because 1 x 30 = 30, 2 x 15=30, 3 x 10 = 30, and 5 x 6= 30.  If the factors are just 1 and that number it is prime.  If there are other factors, it is composite.  30 would be composite.

Step-by-step explanation:

The quickest way to find the factors of a number is to divide it by the smallest prime number( bigger than 1) that goes into it evenly with no reminder. Continue this process with each number you get, UNTIL YOUR REACH 1. I hope it helps :) Let me know
