Answer:
Replace all occurrences of x x in x−y=5 x - y = 5 with 7−y 7 - y . x=7−y x = 7 - y. (7−y)−y=5 ( 7 - y ) - y = 5. Subtract y y from −y - y . x=7−y x = 7 - y. 7−2y=5 7

-21 = -9 + 2/3b
Final Answer: [tex]b = -18[/tex]
Steps/Reasons/Explanation:
Question: Solve [tex]-21 = -9 + \frac{2}{3}b[/tex].
Step 1: Simplify [tex]\frac{2}{3}b[/tex] to [tex]\frac{2b}{3}[/tex].
[tex]-21 = -9 + \frac{2b}{3}[/tex]
Step 2: Regroup terms.
[tex]-21 = \frac{2b}{3} - 9[/tex]
Step 3: Add [tex]9[/tex] to both sides.
[tex]-21 + 9 = \frac{2b}{3}[/tex]
Step 4: Simplify [tex]-21 + 9[/tex] to [tex]-12[/tex].
[tex]-12 = \frac{2b}{3}[/tex]
Step 5: Multiply both sides by [tex]3[/tex].
[tex]-12[/tex] × [tex]3 = 2b[/tex]
Step 6: Simplify [tex]-12[/tex] × [tex]3[/tex] to [tex]-36[/tex].
[tex]-36 = 2b[/tex]
Step 7: Divide both sides by [tex]2[/tex].
[tex]-\frac{36}{2} = b[/tex]
Step 8: Simplify [tex]-\frac{36}{2}[/tex] to [tex]-18[/tex].
[tex]-18 = b[/tex]
Step 9: Switch sides.
[tex]b = -18[/tex]

Steven's basketball team won 5 out of their first 12 games. If they continue to win at this rate, how many games will they lose if they play 49 games?
Answer:
Number of game lose = 29 games (Approx)
Step-by-step explanation:
Given:
Winning part = 5/12
Total game = 49
Find:
Number of game lose
Computation:
Lose part = 1 - 5/12
Lose part = 7/12
Number of game lose = Total game x Lose part
Number of game lose = 49 x [7/12]
Number of game lose = 28.58
Number of game lose = 29 games (Approx)
They would lose 29 games if they play 49 games
They won 5 out of their first 12 games.
Hence the number of game lost in their first 12 games = 12 - 5 = 7 games
The rate at which they lose = 7 games / 12 games
Given that they played 49 games, hence:
Number of games lost = (7 games / 12 games) * 49 = 28.58
They would lose 29 games if they play 49 games

Which answer shows two pairs of adjacent in the figure
Answer:
Supplementary angles
Step-by-step explanation:
Definition of supplementary angles :
"If the sum of two adjacent angles is 180°, angles are said to be supplementary angles."
m∠ABC + m∠CBD = 90° + 90° [Given]
m∠ABC + m∠CBD = 180°
Therefore, both the angles are supplementary angles.

Find all the missing elements:
B
a
A = 40°
a = 8
b = 7
A
C
b
B = [?]° C = [ ]° c =
C=[ ]
Round to the nearest tenth.
Enter
Answer:
B = 34.2°
C = 58.2° or 121.8°
c= 10.6
Step-by-step explanation:
Step 1
Finding c
We calculate c using Pythagoras Theorem
c²= a² + b²
c = √a² + b²
a= 8, b = 7
c = √8² + 7²
c = √64 + 49
c = √(113)
c = 10.630145813
Approximately c = 10.6
Step 2
Find B
We solve this using Sine rule
a/sin A = b/sin B
A = 40°
a = 8
b = 7
Hence,
8/sin 40° = 7/sin B
8 × sin B = sin 40° × 7
sin B = sin 40° × 7/8
B = arc sin (sin 40° × 7/8)
B ≈34.22465°
Approximately = 34.2°
Step 3
We find C
Find B
We solve this using Sine rule
b/sin B = c/sin C
B = 34.2°
b = 7
c = 10.6
C = ?
Hence,
7/sin 34.2° = 10.6/sin C
7 × sin C = sin 34.2 × 10.6
sin C = sin 34.2° × 10.6/7
C = arc sin (sin 34.2° × 10.6/7)
C = arcsin(0.85)
C= 58.211669383
Approximately C = 58.2°
Or = 180 - 58.2
C = 121.8°
Answer:
C=105.8 degrees. c=12

find the value of in the triangle below ! help pls
Answer:
0<x<5
Step-by-step explanation:
I assume based on the question that you are in a geometry class, so you should understand this. Based on the triangle inequality theorem, the sum of two sides of a triangle are greater than the third side. Using this, we can say that x+3+3 should be greater than 5. since 3+3 is already six regardless of what x is, we know that as long as x is greater than 0 it meets this requirement. Also, if 5 and 3 are added they should be greater. 5+3=8, so x must be less than 5 for the 5 and 3 sides to be greater.

For the funtion f(x)= (x+7)^5, Find f^-1 (x)
a: f^{-1}(x)=\sqrt[5]{x}+7f −1(x)=5x +7
b: f^−1(x)=x 5 −7
c: f −1(x)=5sqrtx−7
d: f ^−1(x)= 5sqrtx−7
Answer:
The inverse of function [tex]f(x)= (x+7)^5[/tex] is [tex]\mathbf{f^{-1} (x)=\sqrt[5]{x}+7}[/tex]
Option A is correct option.
Step-by-step explanation:
For the function [tex]f(x)= (x+7)^5[/tex], Find [tex]f^{-1} (x)[/tex]
For finding inverse of x,
First let:
[tex]y=(x+7)^5[/tex]
Now replace x with y and y with x
[tex]x=(y+7)^5[/tex]
Now, solve for y
Taking 5th square root on both sides
[tex]\sqrt[5]{x}=\sqrt[5]{(y+7)^5}\\\sqrt[5]{x}=y+7\\=> y+7=\sqrt[5]{x}\\y=\sqrt[5]{x}-7[/tex]
Now, replace y with [tex]f^{-1} (x)[/tex]
[tex]f^{-1} (x)=\sqrt[5]{x}+7[/tex]
So, the inverse of function [tex]f(x)= (x+7)^5[/tex] is [tex]\mathbf{f^{-1} (x)=\sqrt[5]{x}+7}[/tex]
Option A is correct option.
400 times 45.2
Show all work
Answer: 18080!
Step-by-step explanation:400 x 450
1. Multiplying from the oneths place ( turning 45.2 into 450)
2x0=0 2x0=0 2x4=8 = So the first answer is 800
2. Multiply from the tenths place
5 x 0 = 0 5 x 0 = 0 5 x 4 = 20 = the second answer is 2000
Multiplying the hundredths place
4 x 0 = 0 4 x 0 = 0 4 x 4 = 16 = The third answer is 1600
800 + 2000 + 1600 = 18080 Hope this helped! :)

How can we determine inequality using position on a number line?
Answer:
To plot an inequality, such as x>3, on a number line, first draw a circle over the number (e.g., 3). Then if the sign includes equal to (≥ or ≤), fill in the circle. If the sign does not include equal to (> or <), leave the circle unfilled in.

Need help with Pythagorean Theorem
Answer: -4 and 4
Step-by-step explanation:
In mathematics, the Pythagorean theorem, or Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides.
Answer:
leg a is 3 units and leg b is 8 units
Step-by-step explanation:
[tex]3^{2} + 8^{2} =73[/tex]
[tex]\sqrt{73} = 8.5[/tex]
so the hypotenuse is 8.5 hope this helps
Kendra surveyed 100 people who own a dog or a cat, or both. Of those surveyed, 15 one both a dog and a cat, and the number of people who people who own a dog is four times the number of people who own a cat. How many people surveyed own a cat?
Answer:
40people
Step-by-step explanation:
Let the number of those that owned a dog be x
Let the number of those that owned a cat be y
If the number of people who own a dog is four times the number of people who own a cat, then:
x = 4y
Since x+y =100
4y+y = 100
5y = 200
y = 200/5
y = 40
x = 4(40)
x = 160
Hence 40 people surveyed own a cat

ILL GIVE BRAINLEST!!!! A crafter is making a triangular flag. She has two sides of length 24 inches and 36 inches. What are the length possibilities (in whole inches) for the third side?
A. 12 in. or less
B. 60 in. or more
C. between 13 in. and 59 in.
D. not possible
Given :
A crafter is making a triangular flag.
She has two sides of length 24 inches and 36 inches.
To Find :
The length possibilities (in whole inches) for the third side.
Solution :
We know, the sum of two sides of any triangle is always greater than the length of the third side.
Let, third side is d.
So, d is always less than the sum of other sides i.e. ( 24 + 36 ) = 60 .
d < 60
Also, difference between the difference of length is always less than the side.
So, d > 36 - 24
d > 12
Therefore, the length possibilities for the third side is between 13 inches and 59 inches.

HELPPPPPPPPPPP me and my sister in theEmma is standing 20 yards from a billboard as shown. The bottom of the billboard (B) is 6 yards above the ground, and the top (T) is 10 yards above the ground. What elevation angles might Emma use in order to read messages on the billboard? Select all that apply.
Answer:
Most reasonable: 16°, 20° and 22°
If Emma is very short, 25°
Step-by-step explanation:
This is trigonometry using Tangent and arc-tan
Tan=opp/adj
The length of the adjacent is 20 yards. The opposite lengths given are the bottom, 6 yards and the top, 10 yards. Assuming Emma is of average height, it seems reasonable to subtract about 1.7 to 1.9 yards, the distance of her eyes above ground level, for accuracy. But that may not be necessary, given the range of angles.
I subtracted 1.8, about 5'6"
Calculating tangent from the top:
8.2/20 = .41. arc-tan .41= 22.3°
tangent for the bottom:
4.2/20= .21 arc-tan .21 = 11.8°
If you are using a scientific calculator, once you have the ratio of the opp to adj in decimal form, use the tan- key then the decimal to convert to degrees.
