m24 =

m25 =
Answer/Step-by-step explanation:
✔️m<1 + 52° = 180° (consecutive angles angle)
m<1 = 180 - 52
m<1 = 128°
✔️m<2 = 52° (alternate interior angles are congruent)
✔️m<3 = 47° (alternate interior angles are always equal)
✔️m<4 + 47° = 180° (consecutive angles)
m<7 = 180 - 47
m<7 = 133°
✔️m<5 = 180 - (52 + 47)
m<5 = 180 - 99
m<5 = 81°

Step 2: Solve for x
Distribute -2: -2x - 10 = -2x + 4 + 5Add: -2x - 10 = -2x + 9Add 2x on both sides: -10 ≠ 9Here we see that -10 does not equal 9.

What is a quadratic equation? And how do you solve them?
Answer:
A quadratic equation is some thing like
(x+2)^2
or
(x+2)(x+5)
In order to solve them, the most basic method is the FOIL method
F-First
O-Outside
I-Inner
L-Last
So for example
(x+2)^2
Which is basically
(x+2)(x+2)
So the first is the 2 Xs
(x+2)(x+2)
x*x=x^2
The outer is the x and the 2,
(x+2)(x+2)
2*x=2x
Now the Inner which is the 2 and the x
(x+2)(x+2)
2*x=2x
And finally the last which is the 2 and the second 2
(x+2)(x+2)
2*2=4
Now add them all up
X^2+2x+2x+4
Combine like terms
x^2+4x+4
There you have it
Do the same with every other quadratic equation

DE is a Mid-segment of triangle ABC. How long is DE?
Answer:
DE = 14
Step-by-step explanation:
Since, DE is a Mid-segment of triangle ABC.
Therefore,
DE = 1/2 * AC
2 DE = AC

Step-by-step explanation:
Which graph represents the proportional relationship given by the rule "y is 3 times the value of x"?
Please answer fast less than 5 min
Answer:
The fourth graph i.e. RIGHT BOTTOM GRAPH is correct which represents the proportional relationship given by the rule y = 3x.
Also, the correct graph is attached below.
Step-by-step explanation:
Given the rule
''y is 3 times the value of x".
It means
y = 3x
comparing with the slope-intercept form of the line equation
y = mx+b
where y is the slope and b is the intercept
so,
The slope of y = 3x will be: m = 3
The y-intercept of y = 3x will be: b = 0
CHECKING THE 4TH GRAPH (THE RIGHT BOTTOM SIDE)
Taking two points
(0, 0)
(2, 6)
Finding the slope between (0, 0) and (2, 6)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [6 - 0] / [2 - 0]
= 6 / 2
= 3
Thus, the slope of the line = m = 3
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 0
Thus, the y-intercept b = 0
Now, substituting m = 3 and b = 0 in the slope-intercept form of linear function
y = mx+b
y = 3x+0
y = 3x
Therefore, the fourth graph i.e. RIGHT BOTTOM GRAPH is correct which represents the proportional relationship given by the rule y = 3x.
Also, the correct graph is attached below.
Answer:
It's the bottom right graph.

A right triangle has vertices at (0,9), (4,9) and (4, 4). What is the equation of the line that includes the hypotenuse? y =
Answer:
y = - 1.25x + 9
Step-by-step explanation:
A(0,9) B(4,9) C(4,4)
AB² = (4-0)² + (9-9)² = 16
AC² = (4-0)² + (4-9)² = 41
BC² = (4-4)² + (4-9)² = 25
AC is hypotenuse with y interception of 9
slope = 5/4 = -1.25
equation: y = - 1.25x + 9
A 22 inch TV costs $140.
It is on sale for 20% off.
How much will you save?
Answer:28 dollar
Step-by-step explanation: 140 x (20/100)= 28 dollar
140-28= 112 the price after the sale
Answer: you will save $28.
Step-by-step explanation:
To find a percent of a number you have to turn the percent into a decimal. For example you would turn 20% into 0.20 then multiply this by 140. After doing this you will find out that 20% of 140 is 28.

an electronics warehouse ships televisions and DVD players in certain combinations to retailers throughout the country. The weight of 4 Televisions and 6 DVD players is 70 pounds, and the weight of 2 televisions and 5 DVD players is 37 pounds. Let represent the amount of pounds per TV and represent the amount of pounds per DVD. How much did each television and DVD player weigh?
Answer:
d = 1
t = 16
Step-by-step explanation:
Television = t
DVD = d
4t + 6d = 70
2t + 5d = 37
2t + 5d = 37
2t = 37 - 5d
2t/2 = 37/2 - 5d/2
t = 18.5 - 5/2d
4t + 6d = 70
4(18.5 - 5/2d) + 6d = 70
74 - 10d + 6d = 70
-4d = -74 + 70
-4d = -4
-4d/-4 = -4/-4
d = 1
2t + 5d = 37
2t + 5(1) = 37
2t + 5 = 37
2t = 37 - 5
2t = 32
2t/2 = 32/2
t = 16
Check: d = 1; t = 16
4t + 6d = 70
4(16) + 6(1) = 70
64 + 6 = 70
70 = 70
2t + 5d = 37
2(16) + 5(1) = 37
32 + 5 = 37
37 = 37

If a circle has a radius of 8 cm, what is its diameter?
a.
8 cm
c.
4 cm
b.
16 cm
d.
½ cm
Answer:
A = 16cm
B = 32cm
C = 8cm
D = Sorry the time I learned this I didn't learn it for fractions.
There are two other important distances on a circle, the radius (r) and the diameter (d). The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pie you can calculate the circumference.
The diameter is the distance from one side of the circle to the other at its widest points. The diameter will always pass through the center of the circle. The radius is half of this distance.
The formula for working out the circumference of a circle is:
Circumference of circle = π x Diameter of circle
This is typically written as C = πd.

the ratio is 1:8
blank gallons of orange juice per 1 gallon of app
le juice is 1/8
8 gallon of apple juice = 1 gallon of orange juice
1 gallon of apple juice = 1/8 gallon of orange juice
1920 gallon of apple juice = 1/8 * 1920 gallon of orange juice
= 1/8 * 1920 = 240 gallon of orange juice
1 gallon of orange = 8 gallon of apple
6260 gallon of orange = 8 * 6260 gallon of apple

All the angles make a full circle which needs to equal 360 degrees.
Add all the angles together to equal 360:
X + (x-10) + (4x-20) +(2x-10) + (x +10) = 360
Combine like terms:
9x -30 = 360
Add 30 to both sides:
9x = 390
Divide both sides by 9:
X = 390/9
X = 43.3333. ( 43 and 1/3)
Answer:
x = 43 1/3 degrees.
Step-by-step explanation:
All these angles add up to 360 degrees , so we have:
x - 10 + 4x - 20 + 2x - 10 + x + 10 + x = 360
9x - 30 = 360
9x = 390
x = 390/9
= 43 1/3 degrees

Choose all the problems that you will solve by regrouping. A. 65 – 56 = ? B. 28 – 15= ? C. 16 – 6 = ? D. 74 – 38 = ?
Answer:
(a) and (d) will be done by regrouping
Step-by-step explanation:
Solution will be done by regrouping if unit term of term which is subtracted is greater then the term which subtracts.
(a) 65 -56, since the unit term of 65 is 5 and of 56 is 6
as the unit terms of 56 is greater than unit term of 65
Thus solution will be done by regrouping
⇒ 65 -56 = 9
(b) 28 -15, since the unit term of 28 is 8 and of 15 is 5
as the unit terms of 28 is greater than unit term of 15
Thus solution will not be done by regrouping
⇒ 28 -15 = 13
(c) 16 -6, since the unit term of 16 is 6 and of 6 is 6
as the unit terms of 16 is equal to unit term of 6
Thus solution will not be done by regrouping
⇒ 16 -6 = 10
(d) 74-38 , since the unit term of 74 is 4 and of 38 is 8
as the unit terms of 38 is greater than unit term of 74
Thus solution will be done by regrouping
⇒ 74-38 = 36

4/9 x 25 = 100/9
Area of picture is: 11.11 cm^2
Step-by-step explanation:
The area of the square will be equal to 11.11 square centimetres.
The space covered by the two-dimensional object on a plane is called as an area. The space covered by the square in a two-dimensional plane is called the area of the square.
The square is a quadrilateral having four sides and all the sides of the square are equal to each other.
The the area of the square is calculated as,
a² = 5²=25 cm²
The picture area is 4/9 of the total
area.
4/9 x 25 = 100/9
