The angles below AB will add to 180°.
.. x +2x +x +3x = 180°
.. 7x = 180°
.. x = 180°/7 ≈ 25.71°

Vertical angles AOC and BOD are equal, so
.. 2y = 3x
.. y = (3/2)*x = (3/2)*25.71° = 38.6° . . . . . . . . corresponding to selection D.

___
There is an "x" missing next to segment OC. "2" should be "2x".

Notice that 2y and 3x are vertical angles, which means they are equal.
2y=3x

the four angles below the line AB make a sum of 180
3x+x+2x+x=180
7x=180
x=180/7

2y=3x=3*180/7=540/7
y=270/7≈38.6
d is the answer.

larisa [96]

The total pounds of shrimp they catch is 9.625 pounds

<h3>Sum of values and decimals</h3>

Decimal number are numbers that has decimal points. Given the following information;

The total shrimp Spencer catch = 2 pounds

The total shrimp Jaclyn catch = 3.25 pounds

The total shrimp Ayden catch = 4.375 pounds

Determine the total pounds of shrimp they catch

Total shrimp = 2 + 3.25 + 4.375

Total shrimp = 9.625 pounds

Hence the total pounds of shrimp they catch is 9.625 pounds

If x=5^a, find the value of 5x. How?

Yakvenalex [24]

Answer:

$5x = 5^{(a+1)}$

Step-by-step explanation:

Here is a problem with the concept of properties of the exponent.

We are given $x = 5^{a}$ and we have to find the value of 5x.

Now, $5x = 5 \times 5^{a}$ {Since we are given that $x = 5^{a}$ }

⇒ $5x = 5^{1} \times 5^{a}$ {Since we can write $x = x^{1}$ }

⇒ $5x = 5^{(a+1)}$ {Since we know the formula of exponent as $x^{m} \times x^{n} = x^{(m + n)}$ }

If x = 2 calculate the value of x squared- x

monitta

Plug the x value which is 2 back to the x and solve.

I gave you two answers because I wasn’t sure if the question was (x^2) - 2 or x^2-2.
Those two functions look similar but is totally different so keep that in mind.

Hope you have a victorious day!
