[tex](6w - 7) + (3x + 8) = 142[/tex]
[tex]6w + 3x - 7 + 8 = 142[/tex]
[tex]6w + 3x + 1 = 142[/tex]
Subtract sides -1
[tex]6w + 3x + 1 - 1 = 142 - 1[/tex]
[tex]6w + 3x = 141[/tex]
Divided sides by 3
[tex] \frac{6}{3}w + \frac{3}{3}x = \frac{141}{3} \\ [/tex]
[tex]2w + x = 47[/tex]
I call above equation (( Ω ))
_________________________________
Step (2)
[tex]180 - 142 = 38[/tex]
We have :
[tex](6w - 7) + 38 = (10w - 9)[/tex]
[tex]6w - 7 + 38 = 10w - 9[/tex]
[tex]6w + 31 = 10w - 9[/tex]
Subtract sides -6w
[tex]6w - 6w + 31 = 10w - 6w - 9 \\ [/tex]
[tex]31 = 4w - 9[/tex]
Plus sides 9
[tex]31 + 9 = 4w - 9 + 9[/tex]
[tex]40 = 4w[/tex]
Divided sides by 4
[tex] \frac{40}{4} = \frac{4}{4}w \\ [/tex]
[tex]w = 10[/tex]
_________________________________
Do u remember (( Ω )) ?
Of course u do...
[tex]2w + x = 47[/tex]
[tex]2(10) + x = 47[/tex]
[tex]20 + x = 47[/tex]
Subtract sides -20
[tex]20 - 20 + x = 47 - 20[/tex]
[tex]x = 47 - 20[/tex]
[tex]x = 27[/tex]

a triangle has the following two angle measures:
based on the angles given the third angle must have a measure of _______?
Answers
Answer:
62°
Step-by-step explanation:
Given that the triangle has two angle measures of 41° and 77°.
All the angles in a triangle must add up to 180° (e.g. 20° + 60° + 100°). So we write a simple equation to solve for the mystery angle measure:
Let x = the missing measure
[tex]41 + 77 + x = 180[/tex]
Now that we have our equation, let's start solving it. First, we need to add 41 and 77 together which simplifies the equation: [tex]118 + x = 180[/tex]
Then we subtract 118 from both sides to isolate x - this will give us the value of this variable: [tex]x = 62[/tex]
Therefore, the third angle must have a measure of 62°.

A motorized float in a Thanksgiving Day parade is traveling north at a speed of 16.0 km/h. Part of a "Pilgrim" woman's role in the thematic vignette is to walk across the float to call the men to dinner. She walks at a speed of 3.22 km/h east as the float passes the judge's booth, which is on the west side of the street. What is the woman's velocity with respect to the judge?
Answers
Answer:
16.32 N11.38°E km/h
Step-by-step explanation:
16.0∠0° +3.22∠90° ⇒ (x, y) = (3.22, 16.0) ⇒ (r, θ) =
(3.22, 16.0) ⇒ (r, θ) = (√(3.22² +16²), arctan(3.22/16)*) = (16.32, 11.38°)
The woman's velocity is 16.32 km/h in a direction that is 11.38° east of north.

What is the solution to the following system of equations?

(5,0)
(0,5)
(7,0)
(0,7)
Answers
Answer:
What do you mean?
Step-by-step explanation:
Answer:
( 5, 0 )Step-by-step explanation:
x - 3y = 5
2x + y = 10 multiply by 3 to eliminate y and solve for x
x - 3y = 5
6x + 3y = 30 then add
7x = 35
simplify:
x = 35 / 7
x = 5
substitute x = 5 back into the eq.2
2x + y = 10
2(5) + y = 10
y = 10 - 10
y = 0
therefore the answer is ( 5, 0 )

In a cinema theatre, why do we normally not hear echoes even though the sounds are loud?
Answers
Answer:
An echo is formed as a result of reflection of the original sound which returns to the listener. You might have experienced Echo in an EMPTY ROOM but no echo is produced after the room is occupied. To avoid echo from being produced the echo has to be absorbed. Echo in a cinema theatre is absorbed by the WALLS of the theatre.
They are not plain. The walls are corrugated or shaped to form tiny holes or empty spaces to ABSORB the ECHO. Modern Theatre's have ABSORBENT materials sticked to the walls of the theatre.
An echo is an unpleasant sound heard after a produced sound got reflected from a plain surface. It is majorly eliminated in a cinema theater by:
the use of sound absorbing materials in the construction of the wallsabsorption of sound waves by the body and cloths of viewers
Echo is a sound produced due to the reflection of a produced sound by a plain surface. Its continuous occurrence leads to reverberation. It causes distortion of produced sound which makes it unpleasant to hearing. Thus the need for a mechanism which would reduce it to a bearable level.
To reduce or eliminate echo, the walls of the cinema theater had been constructed with sound absorbing materials which may include special pads. These would have been incorporated into the walls, and would absorb most unwanted sounds produced in the theater.
Also the cloths worn by viewers absorbs some of the unwanted sound, thus assisting to indirectly reduce echo.

add three to both sides and minus 6 from both sides becasue you want to get y by itself
5y=-5
now both sides by 5
y=-1
Answer:
y=−1
Step-by-step explanation:
2y+6=1−3y
Step 1: Simplify both sides of the equation.
2y+6=1−3y
2y+6=1+−3y
2y+6=−3y+1
Step 2: Add 3y to both sides.
2y+6+3y=−3y+1+3y
5y+6=1
Step 3: Subtract 6 from both sides.
5y+6−6=1−6
5y=−5
Step 4: Divide both sides by 5.
y=−1

Teresa purchased a prepaid phone card for $15 . Long distance calls cost 24 cents a minute using this card. Teresa used her card only once to make a long distance call. If the remaining credit on her card is $3.96 , how many minutes did her call last?
Answers
Answer:
46 minutes
Step-by-step explanation:
Teresa purchased a prepaid phone for $15
Long distance calls cost 24 cents a minute using this card
She used the card just once to make a long distance call
The remaining credit on her card was $3.96
Therefore the minutes in which her call lasted can be calculated as follows
Let x represent the minutes
15 - 24/100x= 3.96
15-0.24x= 3.96
-0.24x= 3.96-15
-0.24x= -11.04
x= 11.04/0.24
x = 46
Hence Teresa call lasted for 46 minutes

y=-7+2x
Now put it in y intecpet form by putting the 2x first
y=2x-7
Slope is the number before the x.
