Answer:
<A = 117degrees
Step-by-step explanation:
<A and <B are verticle angles, as given. Hence they will be of equal measures. It is given that <A = 5x -3, and <B = 4x + 21.
Using this, set up an equation;
<A = <B
5x - 3 = 4x + 21
Inverse operations,
5x - 3 = 4x + 21
+3 +3
5x = 4x + 24
-4x -4x
x = 24
Now substitute back in, to find the measure of <A,
5x - 3
x = 24
5 ( 24 ) - 3
120 - 3

Find the root of the following equation: (6+x)2−x2=168
Answers
Answer:
No solutions (roots)
Step-by-step explanation:
The root of an equation is basically the solution of the equation. If I'm reading the problem correctly, the equation is (6+x)*2 - x*2 = 168.
We distribute the (6+x)*2 part and get 12+2x - 2x = 168. Uh oh.. the 2x terms cancel each other out and we are left with 12=168. Either I'm reading the equation wrong or the equation has no solutions.

Noah says that to find 20% of a number he divides the number by 5. For example, 20% of 60 is 12, because 60 - 5 = 12. Complete the
statement about whether Noah's method always works.
His method never
works because multiplying by does not give the same result as dividing by 5.

Answer:
A, and D
Step-by-step explanation:
If you go through all the problems, just replace "b" with "(4)" into a calculator. For A and D, they both equaled 180.
The expression that has a value of 180 when b = 4 is D. 51b−24
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
87b - 179 + 957/87.
= 87(4) - 179 + 857/87.
= 348 - 179 + 9.85, will not be 180.
33b12, will not be 180 at b = 4.
b² + 120, will not be 180 at b = 4.
51b - 24.
= 51(4) - 24.
= 204 - 24.
= 180.
11b + 187 - 1756/13.
= 11(4) + 197 - 135.07, will not be 180 at b = 4.

[tex]x=7[/tex]The length of MN = 13The length of NO = 13The length of OM = 13Step-by-step explanation:
As the given triangle is equilateral as all the sides of the triangle are equal.
[tex]MN = 3x-8[/tex]
[tex]NO=2x-1[/tex]
[tex]OM=5x-22[/tex]
As all the sides are equal, i.e.
[tex]MN=NO=OM[/tex]
as
[tex]MN=NO[/tex]
[tex]3x-8=2x-1[/tex]
Add 8 to both sides
[tex]3x-8+8=2x-1+8[/tex]
[tex]3x=2x+7[/tex]
[tex]x=7[/tex]
Hence, the value of x = 7
so putting the value of x to determine the lengths of the
segments MN, NO, and MO
[tex]MN = 3x - 8[/tex]
[tex]= 3(7)-8[/tex]
[tex]=21-8[/tex]
[tex]=13[/tex]
Hence, the length of MN = 13
[tex]NO = 2x-1[/tex]
[tex]=2(7)-1[/tex]
[tex]=14-1[/tex]
[tex]=13[/tex]
Hence, the length of NO = 13
[tex]OM = 5x-22[/tex]
[tex]= 5(7)-22[/tex]
[tex]= 35-22[/tex]
[tex]=13[/tex]
Hence, the length of OM = 13

correct answers only pls.
Answers
Explanation: The number marked by the dot is 1.25. To convert decimals to fractions, think of it as a percent. 1.25% is like 125% (out of 100%) so that would be 125/100. Then divide by GCD (greatest common divider). GCD must be a multiple of both 125 and 100. The GCD in this case is 25. So divide numerator (125) and denominator (100) by 25 to get 5/4. Hope this helps :)
For the school's sports day, a group of students prepared 12 1/2 litres of lemonade. At the end of the day they had 2 5/8 litres left over. How many litres of lemonade were sold?
Answers
Given :
For the school's sports day, a group of students prepared 12 1/2 litres of lemonade. At the end of the day they had 2 5/8 litres left over.
To Find :
How many litres of lemonade were sold.
Solution :
Initial amount of lemonade, I = 12 1/2 = 25/2 litres.
Final amount of lemonade, F = 2 5/8 = 21/8 litres.
Amount of lemonade sold, A = I - F
A = 25/2 - 21/8 litres
A = 9.875 litres
Therefore, 9.875 litres of lemonade were sold.
Hence, this is the required solution.
3(4x+2)=8x+24−2x hhhhhhhh
Answers
Answer: x=3
Step-by-step explanation:
1. First lets do the parenthesis 3(4x+2) to get 12x+6
2. 12x+6=8x+24-2x (combine like terms) first lets do 8x and 2x first so its 8-2= 6x
3. 12x+6=6x+24 (now subtract 12x by 6x to get 6x)
4. 6x+6= 24 (now subtract 24 by 6 to get 18)
5. 6x= 18 (now divide 18 by 6 to get 3)
Answer:
x = 3Step-by-step explanation:
[tex]3(4x+2)=8x+24−2x[/tex]
Expand and simplify
We have
[tex]12x + 6 = 8x + 24 - 2x \\ 12x + 6 = 6x + 24[/tex]
Move 6x to the left side of the equation
[tex]12x - 6x + 6 = 24 \\ 6x + 6 = 24[/tex]
Move 6 to the right side of the equation
[tex]6x = 24 - 6 \\ 6x = 18[/tex]
Divide both sides by 6
[tex] \frac{6x}{6} = \frac{18}{6} \\ [/tex]
We have the final answer as
x = 3Hope this helps you

trey had 440 songs on his mp3 player.now he has 473 songs.what is the percent of increase in the number of songs on his mp3 player?
round to the nearest tenth if necessary.
Answers
Answer:
There is 7.5% increase in the number of songs on his mp3 player.
Step-by-step explanation:
Original Songs in mp3= 440 songs
Final Songs in mp3= 473 songs
We need to find percent of increase in the number of songs on his mp3 player.
The formula used is: [tex]Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100[/tex]
Now putting values and finding percent of increase
[tex]Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100\\Percent \ of \ increase = \frac{473-440}{440} \times 100\\Percent \ of \ increase = 7.5\%[/tex]
So, there is 7.5% increase in the number of songs on his mp3 player.
