Answer:
x = 1/5
Step-by-step explanation:
Step 1: Write equation
-5x - (-7 - 4x) = -2(3x - 4)
Step 2: Solve for x
Distribute: -5x + 7 + 4x = -6x + 8Combine like terms: -x + 7 = -6x + 8Add 6x to both sides: 5x + 7 = 8Subtract 7 on both sides: 5x = 1Divide by 5 on both sides: x = 1/5Step 3: Check
Plug in x to verify it's a solution.
-5(1/5) - (-7 - 4(1/5)) = -2(3(1/5) - 4)
-1 - (-7 - 4/5) = -2(3/5 - 4)
-1 - (-39/5) = -2(-17/5)
-1 + 39/5 = 34/5
34/5 = 34/5

Answer:
True
Step-by-step explanation:
The ratio would be 1:2, which means for every unshaded part there's 2 shaded parts. Looking at the pie chart, we can tell that there are 2 unshaded and 4 shaded. This can mean there are 2:4 unshaded to shaded. Reduced, we get 1:2

What is the constant rate of this? Please show your work.
Answer:
3
Step-by-step explanation:
To find the answer, heres what you need to do.
Basically, you divide each number on the right by the number on the left.
15/5= 3
24/8=3
36/12=3
72/24=3
Since all of the answers are 3, your answer is 3
Answer:
3
Step-by-step explanation:
Slope Formula:
y2 - y1/x2 - x1
Let's use (5, 15) and (8,24)
(x1, y1) = (5, 15)
(y1, y2) = (8, 24)
Substitute:
y2 - y1/x2 - x1
24 - 15/8 - 5
Solve:
24 - 15/8 - 5
9/3
= 3
Therefore the slope, or constant rate is 3.
Tip: look at the relationship between Cost and Time.
15/5 = 3
24/8 = 3
36/12 = 3
72/24 = 3
Dividing is a simple way to find the slope!

1) true or false: Two triangles with three pairs of corresponding congruent angles are congruent.
2) true or false: Two triangles with two pairs of congruent corresponding angles and three pairs of congruent corresponding sides are congruent.
Step-by-step explanation:
TrueFalseFor two triangle to be congruent,there must be any three sides or angle including congruent
Congruent triangles have three pairs of corresponding sides that are congruent, while two triangles that have three pairs of corresponding congruent angles are similar and not necessary congruent. Therefore:
Statement 1 is FALSE.Statement 2 is TRUE.Recall:
Two triangles having three pairs of corresponding sides have the same shape and size, and are congruent.Two triangles having three pairs of corresponding angles have the same shape but may have different sizes. They are rather similar.1. When the two triangles have the three pairs of corresponding angles that are congruent, they can only be said to be similar. They have the same shape but may be of different sizes.
They will be congruent if all corresponding three pairs of sides of both triangles are congruent.Therefore, statement 1 is FALSE.
2. Knowing that three pairs of corresponding sides of two triangles are congruent, it is enough to prove that both triangles are congruent to each other.
Therefore, statement 2 is TRUE.

If l is parallel to m, find the value of each missing variable
Answer:
x = 18
y = 5
Step-by-step explanation:
From the figure attached,
'l' and 'm' are the parallel lines and two transversal lines are intersecting these parallel lines at points A, B and C.
Since, m∠ABC + (7x - 23)° = 180° [Supplementary angles]
m∠ABC = 180° - (7x - 23)°
m∠BCA = (11y - 1)° [Vertical angles]
m∠BAC = 49°
In ΔABC,
m∠ABC + m∠BAC + m∠CAB = 180°
180° - (7x - 23)° + 49° + (11y - 1) = 180°
-7x + 11y = -71
7x - 11y = 71 ------(1)
Since, sum of consecutive angles is 180°
Therefore, m(∠ABC) + (3x + 49)° = 180°
180° - (7x - 23)° + (3x + 49)° = 180°
-4x = -72
x = 18
From equation (1),
7(18) - 11y = 71
11y = 55
y = 5
I kinda need some help
Answer:
x = 32
y = 60
Step-by-step explanation:
By plugging in the equation and solving it, we end up with 32. Then, plugging in 32 for x we get 60 for y when solved.
6y+8 = 7y-12
subtract 8 from both sides
6y = 7y - 12
subtract 7y from both sides
-y = -20
y = 20
4x = 6x-26
subtract 6x from both sides
-2x = -26
x = 13

A line passes through the points A(n,4) and B(6,8) and is parallel to y=2x-5. What is the value of n?
The slope of y = 2x - 5 is 2. Parallel lines have the same slope, so the slope of the line through the given points A and B is also 2. This means
(8 - 4) / (6 - n) = 2
Solve for n :
4 / (6 - n) = 2
4/2 = 6 - n
2 = 6 - n
n = 6 - 2
n = 4
Which is a graph of a proportional relationship?
Which one?
Answer:
third graph (choice three/bottom left)
Step-by-step explanation:
Anything with a proportional relationship will always have a constant ratio (ratios will always be equivilent).
you can eliminate any graph that has an x or y intercept other than zero, or does not have a straight line.
The two main rules of a proportional graph or direct proportion is that:
the line must go through the origin (0,0)the graph must be linearAnswer:
the bottom left one
Step-by-step explanation:
it starts at the origin and as the x value increases, the y value increases too
you can easily rule out out the top two just because it doesn't start at the origin

sorry if it’s blurry but it says Find the midpoint of the segment with endpoints (6,7) and (6,-5)
The x coordinates, 6 and 6, add to 6+6 = 12. Then we cut this in half getting 12/2 = 6.
The x coordinate of the midpoint is 6.
The y coordinates, 7 and -5, add to 7+(-5) = 2. Which cuts in half to get 2/2 = 1.
The y coordinate of the midpoint is 1.
Put together, the midpoint is located at (6,1)

The figure shows how the yard lines on a football field are numbered. The goal lines
are labeled G. A referee was standing on a certain yard line as the first quarter ended.

He walked 41 yards to a yard line with the same number as the one he had just left.
4
How far was the referee from the nearest goal line? Express your answer as a
simplified mixed number.
9514 1404 393
Answer:
29 1/8 yards
Step-by-step explanation:
If the ref is distance 'd' from the goal line, after walking 41 3/4 yards to the same yard line at the other end of the field, he will also be at distance d from that goal line.
Hence the total ...
d + 41 3/4 + d
will be the length of the field between goal lines, 100 yards.
2d +41 3/4 = 100
2d = 58 1/4 . . . . . . subtract 41 3/4
d = 29 1/8 . . . . . . . divide by 2
The referee was 29 1/8 yards from the nearest goal line.

Find the values of x, y, and z in the triangle to the right. A triangle has angles labeled as follows: lower left, x degrees; top, y degrees; lower right, z degrees. A ray extends the left side of the triangle and the angles labeled y degrees and (3 x plus 5) degrees form a straight angle. Another ray extends the bottom side of the triangle and the angles labeled z degrees and (3 x minus 5) degrees form a straight angle. X degrees y degrees z degrees left parenthesis 3 x plus 5 right parenthesis degrees left parenthesis 3 x minus 5 right parenthesis degrees
Given:
Consider the below figure attached with this question.
Angles of a triangle are x, y and z.
To find:
The values of x, y and z.
Solution:
If two angles are linear pair, then their sum is 180 degrees.
[tex]y+(3x+5)=180[/tex]
[tex]y=180-3x-5[/tex]
[tex]y=175-3x[/tex]
Similarly,
[tex]z+(3x-5)=180[/tex]
[tex]z=180-3x+5[/tex]
[tex]z=185-3x[/tex]
According the the angle sum property, the sum of all angles of a triangle is 180 degrees.
[tex]x+y+z=180[/tex]
[tex]x+(175-3x)+(185-3x)=180[/tex]
[tex]-5x+360=180[/tex]
[tex]-5x=180-360[/tex]
[tex]-5x=-180[/tex]
Divide both sides by -5.
[tex]x=36[/tex]
The value of x is 36.
[tex]y=175-3(36)[/tex]
[tex]y=175-(108)[/tex]
[tex]y=67[/tex]
Now,
[tex]z=185-3(36)[/tex]
[tex]z=185-108[/tex]
[tex]z=77[/tex]
Therefore, the values of x, y and z are 36, 67 and 77 respectively.
