Answer:
x=-2
y=9
Step-by-step explanation:
Multiply one of the equations to get negative terms with equal y coefficients. Add them together then solve for x.
Substitute x in one of the equations then solve for y.
You can check your answer by substituting x and y into one equation and solving to obtain the same answer on the right side of the equation.

Which of the angles in the figure are supplementary to Ð5?
Answers
Answer:
Option C) Angle 6 and 7 only
Step-by-step explanation:
Two angles are called supplementary when their measures add up to 180 degrees.
So here the angle supplementary to Angle 5 would be 6, since adding both would get us 180 degrees. Then there's angle 7 which would also give us 180 degrees when added to angle 5.

Erica solved the equation −5x − 25 = 78; her work is shown below. Identify the error and where it was made. (5 points)
−5x − 25 = 78
Step 1: −5x − 25 − 25 = 78 − 25
Step 2: −5x = 53
Step 3: = -5x/-5=53/-5
Step 4: x = -53/5
Answers
−5x − 25 = 78
Step 1: −5x − 25 − 25 = 78 − 25 WRONG
- 5x - 25 = 78
- 5x - 25 + 25 = 78 + 25
- 5x = 103
x = - 103/5
x = - 20,6
Answer:
Step-by-step explanation:
−5x − 25 = 78
Step 1: −5x − 25 − 25 = 78 − 25 <== this is where the error was made.
Step 2: −5x = 53
Step 3: = −5x/−5=53/−5
Step 4: x = −53/5
Right steps:
−5x − 25 = 78
Step 1: −5x − 25 + 25 = 78 + 25
Step 2: −5x = 103
Step 3: −5x/−5 = 103/−5
Step 4: x = 103
Step 1 was where the error was, because she subtracted 15 from both sides instead of adding 15, so they cancelled out.

Answer:
Write the absolute value equations in the form
x−b
=c (where b is a number and c can be either number or an expression) that have the following solution sets.
Chapter Reference
a
Two solutions: x=2, x=14.
Step-by-step explanation:
The absolute value equations in the form |x-b|=c is 6.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that;
Two solutions are x=2 and x=14
Now,
To write an absolute value equation that has these solutions, we need to find a common value of b and c that satisfy the property above. One possible way to do this is to find the midpoint and the distance between the two solutions. The midpoint is the average of the two solutions, and the distance is half of their difference. The midpoint will be the value of b, and the distance will be the value of c.
Using this method, we get:
b = (2 + 14) / 2 = 8
c = (14 - 2) / 2 = 6
Therefore, by the given equation the answer will be 6

Hamid's soccer game is 2 hrs. and 15 mins. long. The game starts at 11:00 A.M. The park closes at 6:30 P.M. Each soccer game is the same as Hamid's game. How many more games can be played before the park closes?
Answers
Answer:
e
Step-by-step explanation:
Soccer game lasts 2 hours and 15 minutes
The game starts at 11:00 A
The park closes at 6:30
The first thing we need to do is to find when Hamid's soccer game finishes
2 1/4 + 11:00 = 13 1/4 = 1:15
(uh so don't know if this is the correct formula for finding time but the answer is correct)
Guessing that each game lasts 2 hrs and 15 mins, we do the same thing
1.25 + 2.25 = 3.75 = 3 3/4 = 3:45
(i added decimals bc i find it the easiest way for me) 1 game
3.75 + 2.25 = 6 (another game)
The answer is 2 games including Hamid's soccer game.

this is NOT 0/0. you can't add numerator and denominator. when you have the same denominator, you can only add the numerator.
and don't forget : -×- and -/- are both + !
2B
you do not multiply anything. you ADD (but again NOT the denominators) !
and +×- or +/- = - !
overall this this adding a negative number to the same positive number. the result : always 0
2C
cannot be added like that. first you would have to bring both to a common denominator. but then you ADD !
2D
very similar to 2C.

Use the diagram below, if m∠AEC=41°, find each angle measure
Answers
Answer:
[14] 139
[15] 90
[16] 41
[17] 49
[18] 139
[19] 131
Step-by-step explanation:
[14] Since m ∠ CEB is vertical with m ∠ AED = 139
[15] Knowing that m ∠FBD = 90 degree then m ∠ CEF = 90 degree
[16] Since m ∠ DEB is vertical to m ∠ADC Thus answer = 41
Note: vertical angles are angles opposite each other where two lines cross.
[17] Since m ∠ FED = 90 degree and m ∠ DEB = 41 then 90 - 41 = 49
[18] To Find m ∠CEB we have to subtract from m ∠ DEB
180 - 41 = 139
[19] Knowing that m ∠ FED = 90 degree and m ∠DEB = 41
Then m ∠ AEF = 90 +41=131
