S5. ∠2 is supplementary to ∠3 {}      R5. Linear pair angles are supplementary

S6. m∠2 + m∠3 = 180°              {}                Definition of supplementary angles

S7. m∠1 + m∠3 = 180°              {}                 Substitution Property of Equality  

S8. ∠1 is supplementary to ∠3           {}      Definition of supplementary angles

Question 2:

(a) The property of a square that is also a property of a rectangle is that all the interior angles of both a square and a rectangle equal

(b) The property of a square that is not necessarily a property of all rectangles is that the sides of a square are all equal, while only the length of the opposite sides of a rectangle are equal

(c) The property of a rhombi that is also a property of a square is that all the sides of a rhombi are equal

(d) A property of a rhombi that is not necessarily a property of all parallelogram is that the diagonals of a rhombi are perpendicular

(e) A property that applies to all parallelogram is that the opposite sides of all parallelogram are equal

Rearrange the equation so u is the independent variable. -12u+13=8w-3 <br><br> w= ___
Rama09 [41]

Answer:

w = \frac{-12u+16}{8}

Step-by-step explanation:

Reverse the equation placing w on the left side

8w - 3 = - 12u + 13 ( add 3 to both sides )

8w = - 12u + 16 ( divide both sides by 8 )

w = \frac{-12u+16}{8}

Evaluate 7(-4) - |-6| + |4| <br> A. 13<br> B.-18<br> C. -30
tester [92]

Hello there!

Answer: ⇒ C. -30

_________________________________________________________

Step-by-step explanation:

First you had to remove parenthesis.

-7*4-|-6|+|4|

Then you multiply by the number.

=-28-|-6|+|4|

Apply absolute value.

|-6|=6

=-28-6+|4|

Again apply absolute value.

|4|=4

=-28-6+4

Simplify it's should be the correct answer.

=-30

Hope this helps!

Thank you for posting your question at here on brainly.

Have a great day!

4x+5-2=3x+7x-15 I dont get how to get the answer for this please help.
fredd [130]
Hello there! How are you today?

4x + 5 -2 = 3x + 7x - 15

First, we need to get the variable (x) on one side. To do that, we must simplify the right side of the equation, and then decide what to do from there, so let's proceed to do so.

3x + 7x = 10x

4x + 5 - 2= 10x - 15

Now we have x simplified on both sides of the equation. However, we need x to be on one side of the equation in order to solve for it.
Subtract 4x from both sides.

4x - 4x = 0
10x - 4x = 6x

We are now left with:
6x - 15 = 5 - 2

Simplify the right side of the equation.

5 - 2 = 3

6x - 15 = 3

Now we need to isolate x. To isolate x, we need to add 15 to both sides, as x is being subtracted by 15, and adding 15 will cancel it out.

-15 + 15 = 0
3 + 15 = 18

We now are left with:
6x = 18

Now we only have one step left, and that is to solve for x. Since x is being multiplied by 6, we need to perform the opposite order of operations to cancel it out. To do that, we must divide both sides by 6 to solve for x.

6x = 18
Divide both sides by 6.

6x / 6 = x
18 / 6 = 3

We are now left with the solution:

x = 3

I hope this helps!

A high school choir had a car wash to raise money, the number of trucks washed was 5 fewer than twice the number of cars washed.
Aneli [31]

Answer:

Step-by-step explanation:

ok so, we know they washed 34.

x-5=Trucks washed [19.5-5=(14.5)]

x=cars washed (19.5)

x+x-5=34

2x-5=34

+5   +5

2x=39

divide 2 both sides

x=19.5

To check work: 19.5+14.5=34!

Hope this helps :)
