Step-by-step explanation:

Hey There!

If you didnt know the given angles in the triangle added together equal the missing triangles supplement aka z+50

So all we have to do is set up an equation

z+50=30+6x-45

step 1 combine like terms

30-45=-15

now we have

z+30=6x-15

step 2 add 15 to each side

-15+15 cancels out

30=15=45

now we have

z+45=6z

step 3 subtract z from each side

z-z cancels out

6z-z=5z

now we have

45=5z

step 4 divide each side by 5

5/5 cancels out

45/5=9

z=5

so we can conclude that z=9

hope this helps :)

Answer:

$\boxed{7-4=11\:or\:6+3=9}$

Step-by-step explanation:

Let $p$ and $q$ be two <em>propositional statements</em>.

The disjunction $p\vee q$ is true if either $p$ or $q$ is true or both are true.

In the given options;

The statement;

$7-4=11$ is false

But;

$6+3=9$ is true.

Hence,

$7-4=11\:\vee \:6+3=9$ is true

The correct answer is D

HELP ME PLEASE ITS DUE TODAY!!!!

Stells [14]

Step-by-step explanation:

$- 5 - ( - 4) = - 5 + 4 = - 1 \\ - 4 - ( - 5) = - 4 + 5 = 1 \\ - 4 - (5) = - 4 - 5 = - 9 \\ 4 - ( - 5) = 4 + 5 = 9$

Therefore ranking them from least to most:

$- 4 - (5) \\ - 5 - ( - 4) \\ - 4 - ( - 5) \\ 4 - ( - 5)$

What is the length, in meters, of the ramp, line segment AC, below? Round to the nearest whole number if necessary.

Brrunno [24]

<em>10 meters.</em>

Step-by-step explanation:

To find the missing side of a right triangle, we can use the <u>Pythagorean theorem</u>.

The Pythagorean theorem is...

$a^2+b^2=c^2$

Please be sure to note that a and b will <em>always </em>be the length of the sides and c will <em>always </em>be the hypotenuse, or in this case the ramp.

Since we know the values of both of the sides we can plug this into the theorem.

$6^2+8^2=c^2$

Now we can solve.

$36+64+c^2$

Add.

$100=c^2$

Many people will make the mistake of thinking 100 is the final answer, but since c is squared we need to find the square root of 100.

$\sqrt{100} =10$

c = 10

<em><u>The ramp is 10 meters.</u></em>

Observe the expression below and select the true statement(s).<br><br> 3y(7 + 2x) + 9xy - 10

Sedaia [141]

Answer:

The "3y" in the first term is a factor

The "9" in the second term is a coefficient

The "(7 + 2x)" in the first term is a factor

Step-by-step explanation:

Given in the question an expression

3y(7 + 2x) + 9xy - 10

The coefficients are the numbers that multiply the variables, x and y.

<h3>Example</h3>

6 is coefficient

2.Constants are terms without variables

<h3>Example</h3>

3.The factors in a mathematical expression are parts of the expression that are connected with multiplication.

<h3> Example</h3>

(4x+1)(3x+7)

(4x+1) and (3x+7) both are factors
