Answer:
Either [tex]x = -15[/tex] or [tex]x = 15[/tex].
Step-by-step explanation:
[tex]|x| = \left\lbrace \begin{aligned} & x && \text{if $x \ge 0$} \\ & -x && \text{if $x < 0$}\end{aligned}\right.[/tex].
Hence, there are two possibilities to consider:
Either [tex](x / 5) \ge 0[/tex],Or [tex](x / 5) < 0[/tex].If [tex](x / 5) \ge 0[/tex], then [tex]|x / 5| = x / 5[/tex].
Substitute into the original equation: [tex]x/ 5= 3[/tex]. Solve for [tex]x[/tex]: [tex]x = 15[/tex].
Important: verify that the solution [tex]x = 15[/tex] meet the assumption [tex](x / 5) \ge 0[/tex]. Indeed, [tex](x / 5) = (15 / 5) = 3[/tex] and is indeed non-negative. Hence, the solution [tex]x = 15\![/tex] is valid.
On the other hand, if [tex](x / 5) < 0[/tex], then [tex]|x / 5| = - x / 5[/tex].
Substitute into the original equation: [tex](-x / 5) = 3[/tex]. Solve for [tex]x[/tex]: [tex]x = -15[/tex].
Similarly, verify that the solution [tex]x= - 15[/tex] satisfies the current assumption that [tex](x / 5) < 0[/tex]. Indeed, this assumption is met, and [tex]x = -15[/tex] is also a valid solution.

tan B = 12/5cos B = 5/13sin B = 12/13Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the applicable ratios:
Tan = Opposite/Adjacent ⇒ tan B = CA/CB = 12/5
Cos = Adjacent/Hypotenuse ⇒ cos B = BC/BA = 5/13
Sin = Opposite/Hypotenuse ⇒ sin B = AC/AB = 12/13

department store are 36, 38, 34, 92, 36, 34, 40, 44, 32, 34 . Find the average size of the pants sold.
Here goes the answer. Hope it helps you.
The pairs of numbers below represent the price of different
quantities of books at 4 stores.
Which pair of numbers represents a proportional relationship?
o 4 books for $24,8 books for $40
o 5 books for $25, 6 books for $36
o 2 books for $14, 5 books for $35
o 3 books for $15, 7 books for $28
Answer:
Option C: 2 books for $14, 5 books for $35
Step-by-step explanation:
A proportional relationship between two quantities would always have a constant of proportionality. Thus,
Constant of proportionality, k = y/x
In this case,
x = quantity of books
y = price
Let's see which pair will have a constant of proportionality:
Option A: 4 books for $24,8 books for $40
24/4 = 6;
40/8 = 5.
No constant of proportionality.
Option B: 5 books for $25, 6 books for $36
25/5 = 5
36/6 = 6
No constant of proportionality.
Option C: 2 books for $14, 5 books for $35
14/2 = 7
35/5 = 7
Constant of proportionality, k = 7.
This pair represents a proportional relationship.
Option D: 3 books for $15, 7 books for $28
15/3 = 5
28/7 = 4
No constant of proportionality.

Starting with the fact that angles 1 and a are a linear pair and that angles b and 2 are also a linear pair, use a two column proof to prove that consecutive interior angles a and bare supplementary ( 5 points)
Answer:
See proof below
Step-by-step explanation:
Two angles that are linear pair sums up to 180°
If angles 1 and a are a linear pair and that angles b and 2 are also a linear pair, then;
1+a = 180....1
2+b= 180....2
Taking the sum of both equations
1+2+a+b = 360°... 3
Note that the sum of the adjacent angles will also be 180° since they also lie on the same straight line, hence;
1+2 = 180°...4.
Substitute 4 into 3
From 3;
1+2+a+b = 360°
(1+2)+(a+b) = 360°
180+(a+b) = 360
a+b = 360-180
a+b = 180
Since the sum of a and b is 180°, this shows that angles are supplementary since the sum of 2 supplementary angles is also 180°
Hence this shows that the consecutive interior angles a and bare supplementary.
Answer:
180-35=145 Degrees
Step-by-step explanation:
TBH I may not have a complete understanding; but what I do know is a straight line (or angel if you so chose) is equal to 180 degrees (NOTE: supplementary- angels are when 2 angels that are added up to 180 degrees) and on my part of the question is: "Starting with the fact that angles 1 and a are a linear pair and that angles b and 2 are also a linear pair, use a two column proof that consecutive interior angles a and b are supplementary".
Now in my whole complete course its asking a bout a ski slope and it gives me the 35 degree angle and we need to figure out the missing angle, we have the same picture as listed above.... knowing that straight lines are 180 degrees I subtracted 180-35 and I got 145 degrees now either i'm right or i'm missing som I did in a few years back but most of my information is basically backed up by some understanding I do know

Angles B and C are supplementary. If m∠B = 2x - 40 and m∠C =2x + 20, how would you determine the measure of each angle?
Answer:
B=60 C=120
Step-by-step explanation:
Supplementary angles add up to 180.
so
2x-40+2×+20=180
4×-20=180
4×=200
×=50
B 2(50)-40=100-40=60
C 2(50)+20=100+20=120
Mr. Ryan had 8 meters of cable. He used 300 centimeters to hook up the television in his living room. Then he used 400 centimeters to hook up the television in his office. How many meters of cable did Mr. Ryan have left?
Answer:
1 meter left
Step-by-step explanation:
100 cm makes up a meter so 300 + 400 is 700 which is 7 meters so he has 1 meter left
Answer:
Mr. Ryan has 1 meter or 100 centimeters ethier (answer is correct)
Step-by-step explanation:
How many meters of cable did Mr. Ryan have left?
Let's start here with that for every meter(m) there is 100 centimeters(cm) so in other words 1 meter = 100 centimeters
300 cm=3 m 400 cm=4 m
3m+4m=7m 300cm+400cm=700cm
__________________________________________________________800cm-700cm=100cm

Since every triangle adds up to 180 degrees the unknown side would be 53!++
Hi mate....
Step-by-step explanation:
This is your answer....
Triangle Fixed Value = 180°
AC = 180 - (30 + 87)
= 180 - 117
= 63°
Checking your answer....
= 117 + 63
= 180°

The composite figure is made up of three simpler shapes. What is the area of the figure?
Please explain how you got your answer, please.
Answer:
C) 55 cm^2
Step-by-step explanation:
(12x3)+(8x2)+(1/2)(3)(2) = 55
The area of composite figure is 55 square cm .
What is area?
The space occupied by a flat shape or the surface of an object is called area.
Formula for the area of triangle[tex]A = \frac{1}{2}bh[/tex]
Where,
A is the area of triangle
b is the base of the triangle
h is the height of the triangle
Formula for the area of parallelogramA = b × h
Where,
A is the area of parallelogram
b is the base of parallelogram
h is the height of the parallelogram
Formula for the area of rectangleA = length × breadth
According to the given figure
Composite figure is made up of triangle, rectangle and parallelogram
Also,
Height of triangle = 3cm
Base of the triangle = 2cm
length of the rectangle = 8cm
breadth of the rectangle = 2cm
Height of the parallelogram = 3cm
Base of the parallelogram = 12cm
Therefore,
Area of triangle = 1/2 × 3 ×2 = 3 square cm
Area of rectangle = 2 × 8 = 16 square cm
Area of parallelogram = 12 × 3 = 36 square cm
Therefore,
Area of the composite figure = area of triangle + area of parallelogram + area of rectangle
⇒ Area of composite figure = 36 + 16 + 13 = 55 square cm.
Hence, the area of composite figure is 55 square cm .
