Answer:
Step 1
Step-by-step explanation:
The symbol seems to have changed from divide to add. The work done in the parentheses is also wrong by the order of operations; multiplication comes before addition.

What are 3 possible solutions for the inequality?
Solve for x. 4x + 3 = 35 Enter your answer in the box.
Answer:
x = 8
Step-by-step explanation:
4x + 3 = 35
subtract 3 from each side
4x = 32
divide 4 from each side
x = 8
3x - 2y =6
if x is equal to -1; 0; 1
Step-by-step explanation:
if X=-1
3(-1) - 2y =6
-3 - 2y =6
-2y=6+3
-2y =9
y=
[tex] \frac{9}{ - 2} [/tex]
y=

Answer:
0.171 m
Step-by-step explanation:
First, let's determine how many mm of track he has in total...
74mm+97mm=171 mm
Now, we can set up a unit converter to convert mm to m (note that 1 mm is [tex]10^{-3{[/tex] m)...
[tex]171mm(\frac{10^{-3}m}{1mm})[/tex]
The "mm" cancels out...
[tex]171*10^{-3}m=0.171m[/tex]
Answer:
Step-by-step explanation:
74 + 97 = 171 mm
Length of the train track = 171 mm = 171÷ 1000 = 0.171 m

Describing a System of Equations
Describe a system of linear equations that has no solution.
Answer:
If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.
Answer:
Sample Response/Explanation: A system consisting of lines that do not intersect will have no solution. Lines will not intersect if they have the same slope, but different y-intercepts. Parallel lines have the same slope, which means they will never intersect.

Discuss the income effect for normal and inferior goods
Answer:
➢ The income effect describes the relationship between an increase in real income and demand for a good. The result of the income effect for a normal good is discernible to that of an inferior good in that a positive income change causes a consumer to buy more of a normal good, but less of an inferior good.

Answer:
I believe your answer is 9
Step-by-step explanation:
The way I found this answer was by assuming that triangle CDE was expanded to get triangle FGH. So I divided 18/4 and got the answer 4.5, which means that the triangle was expanded by a factor of 4.5. So I then multiplied the similar side to HG by 4.5 which was side ED. This got me with 4.5 x 2 and I got the answer 9.
Hope this helps! :)

5m+3(m-3)+7=2m-1
Solve for x
Answer:
=> 5m+3(m-3)+7=2m-1
=> 5m+3m-9+7 = 2m-1
=> 8m-2 = 2m-1
=> 8m-2m = -1+2
=> 6m = 1
=> m = 1/6
Urgent and pls explain thoroughly. O is the centre of the circle. OA, OB and OC are radii. Angle AOB = 72°.
Work out
a) angle OAB b) angle OCB c) angle ABC
Answer:
<ABC=90° <OCB=36° <OAB=54°
Step-by-step explanation:
<ABC=90°
<ocb= half of aob
<oab + <abc+<ocb=180°(triangle abc)
Answer:
a) ∠OAB = 54°
b) ∠OCB = 36°
c) ∠ABC = 90°
Step-by-step explanation:
a)
If O is the center of the circle, then OA and OB are both the radius. Therefore, OA = OB
This means that ΔAOB is an isosceles triangle, as is has two sides of equal length (OA and OB).
The angle between the equal sides (∠AOB) is called the vertex angle. The side opposite the vertex angle (AB) is called the base and base angles are equal. Therefore, ∠OAB = ∠OBA
Given:
The sum of the interior angles of a triangle is 180°∠AOB = 72°∠OAB = ∠OBA⇒ ∠OAB + ∠OBA + ∠AOB = 180
⇒ ∠OAB + ∠OBA + 72 = 180
⇒ ∠OAB + ∠OBA = 108
⇒ ∠OAB = 108 ÷ 2 = 54°
b)
Again, we can see that OB and OC are both the radius, so OB = OC. This means that ΔBOC is also an isosceles triangle, with ∠BOC as the vertex and BC as the base.
Calculate ∠BOC:
Given:
Angles on a straight line add up to 180°∠AOB = 72°⇒ ∠AOB + ∠BOC = 180
⇒ 72 + ∠BOC = 180
⇒ ∠BOC = 108°
Calculate ∠OCB:
Given:
The sum of the interior angles of a triangle is 180°∠BOC = 108°∠OBC = ∠OCB⇒ ∠OBC + ∠OCB + ∠BOC = 180
⇒ ∠OBC + ∠OCB + 108 = 180
⇒ ∠OBC + ∠OCB = 72
⇒ ∠OCB = 72 ÷ 2 = 36°
c)
Thales's theorem is a special case of the inscribed angle theorem and states that:
If A, B, and C are distinct points on a circle where the line AC is a diameter, then ∠ABC is a right angle.Given that AC is the diameter of this circle, and points A, B and C are on the circle, then ∠ABC = 90°

The side lengths of a triangle are 9, 12, and 15. Is this a right triangle?
A. Yes, because 9*2 + 12*2 = 15*2
B. No, because 9*2 + 12*2 ≠ 15*2
C. No, because 9+ 12 ≠ 15.
D. Yes, because 9*2 + 12*2 > 15*2

[1] y = 2x
- the line goes through the origin (0, 0) so there will be no b value
- the line, starting from (0, 0) goes up two and to the right 1 into the next point giving us a slope of 2/1 which simplifies to 2
[2] (0, 5)
- we can figure this out without graphing or plugging in values because (0, y) will be the y-intercept, or the b value
- in this case the value is 5
[3] y = 3x + 12
- it uses a different term than I am used too, but by "graident" I think they mean the slope
- if it has the same slope, then it will be a slope of 3
- if it passes through (0, 12) then again, this is the y-intercept or our b-value
Have a nice day!
-> See attached for more information on b values

The x coordinate is zero and
the y coordinate is positive so what quadrant are they located in
Answer:
If the x-coordinate is (0,0) and the y-coordinate is positive, it is not technically in any quadrant because it is located on the line and not in any quadrant.
Step-by-step explanation:
Some of the steps in Raya's solutions are shown.
Answer:
2. Distributive Property
4. Division Property of Equality
Step-by-step explanation:
2. The reason is Distributive Property since Raya distributed 2.5 to each term in the parentheses:
2.5(6.25x)+2.5(0.5)=11 --> 15.625x+1.25=11
4. The reason is Division Property of Equality since Raya divided both sides by 15.625.
A more in depth version of 3-4:
15.625x+1.25-1.25=11-1.25
15.625x=9.75
Divide both sides by 15.625 (division property of equality since she is dividing the same number from both sides of the equation)
x=0.624

If the lateral surface area of a cylinder with height 4cm is 24pi cm squared then what is its volume?
We are given –
Height of cylinder is = 4cmLateral surface area of cylinder is = 24πcm²We are asked to find volume of the given cylinder.
Let the radius be "r".Then according to the question,it’s given –
[tex]\qquad[/tex] [tex]\pink{\twoheadrightarrow\bf Curved\: surface\: area _{(Cylinder)}= 2\pi r h }[/tex]
[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf 2\pi r h = 24 \pi[/tex]
[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf 2\cancel{\pi} rh = 24 \cancel{\pi}[/tex]
[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf r =\dfrac{24}{2h}[/tex]
[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf r = \dfrac{24}{2\times 4}[/tex]
[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf r = \dfrac{24}{8}[/tex]
[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf r = \cancel{\dfrac{24}{8}}[/tex]
[tex]\qquad[/tex] [tex]\pink{\twoheadrightarrow\bf r = 3 \: cm}[/tex]
Now, Let's find volume of cylinder
[tex]\qquad[/tex] [tex]\purple{\twoheadrightarrow\bf V_{(Cylinder)} = \pi {r}^{2}h}[/tex]
[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf V_{(Cylinder)} = \pi \times 3^2\times 4 [/tex]
[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf V_{(Cylinder)} = \pi \times 9 \times 4[/tex]
[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf V_{(Cylinder)} = \pi \times 36[/tex]
[tex]\qquad[/tex] [tex]\purple{\twoheadrightarrow\bf V_{(Cylinder)} = 36 \pi \: cm^3}[/tex]
Henceforth, volume of cylinder is 36π cm³.Step-by-step explanation:
Given :-
Height is = 4cmLateral surface area of cylinder is = 24πcm²to find :-
volume of the given cylinder.Solution :-
Lateral surface area of cylinder = 2πrh
24π cm = 2πrh
Cancelling π on both the sides ,
24/2h = r
putting the value of h i.e, 4 cm
24/2×4 cm = r
3 cm = radius
Now volume of Cylinder = πr²h
putting all the values ,
Volume = 3.14 × 3² × 4 cm³
Volume = 113.04 cm³

Given, m<7 = 108°
To find, m<3
Since both the given angles are on the same side of transversal, thus there sum is 180°
Thus, m<7 + m<3 = 180°
108° + m<3 = 180°
m<3 = 180° - 108°
m<3 = 72°

Answer:
D. 14
Step-by-step explanation:
These triangles are something called a scale factor. A scale factor means when you multiply any side by that factor, you get the side of the other triangle. It is an exact copy of the triangle from before, just bigger or smaller, also known as set to scale. Here we can do 7/6 to find the scale factor (which is 1.16666666667), and multiply that factor by 12 to get 14.
