Answer:
x = 20
Step-by-step explanation:
4x + 5x = 9x
9x = 180 (supplementary angles add up to 180 degrees)
Divide 180/9 = 20
Answer:
x = 20.
Step-by-step explanation:
Supplementary angles sum to 180, so:
4x + 5x = 180
9x = 180
x = 20.

Answer:
HL
Step-by-step explanation:
Since the ray BD bisects angle ABC, we know angle ABD and angle CBD are congruent through the definition of an angle bisector. Segment AD and segment CD are also congruent because they are equidistant from the bisector. Lastly, segment BD is congruent to segment BD through the reflexive property of equality. This gives the triangles congruency through HL theorem.

Step-by-step explanation:
If its not 1/2 its not 9/10 so that automautically declines 2 answers leaving 5/18 and 5/9. And 5/18 is way to little for a 36 to 20 ratio, so that leaves 5/9.

The expression 3(-2m + 5) - 6(-4m - 2) can be written in the form am + b. What is the value of a + b?
Answer: 45
Step-by-step explanation:
3(-2m + 5) -6(-4m - 2) =
-6m + 15 + 24m + 12=
18m + 27
18= a 27= b 27 + 18= 45
The value of the expression a + b is 45.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
First, we can simplify the expression using the distributive property:
3(-2m + 5) - 6(-4m - 2) = -6m + 15 + 24m + 12
Combining like terms, we get:
18m + 27
So, a = 18 and b = 27, which means:
a + b = 18 + 27 = 45
Therefore,
The value of a + b is 45.

A certain college enrolled 29,000. It was reported 54 percent were female and 46 percent were male. In addition 61 percent were over the age of 25. How many students were in each category if 30 percent of those over the age if 25 were male
Answer:
Step-by-step explanation:
Total number of students = 29000
Number of female = 54% of 29000
54/100 x 29000 = 15660 students
Number of male = 46% of 2900
46/100 x 29000= 13340 students
61% of 29000 are over 25 years
61% of 29000= 61/100 x 29000
= 17690 students
Of the pupils over the age of 25, 30% are male
30% of 17690 students are male
30/100 x 7690 =5307 students
The number of females over the age of 25 = 17690 -5307
17690 - 5307 = 12383 female students.

Pick out the solution from the values given in the bracket next to each equation. Show that the other values do not satisfy the equation. a. X + 12 = 20 ( 12,8,20,0) b. P - 4 = 0 (4,-4,8,0) c. 2y - 3 = 7 (0,3,5,7) Plz explain ;)
Answer:
(a) 8
(b) 4
(c)5
Step-by-step explanation:
We are given multiple parts and we need to provide the correct answer among the given options, also we need to prove that rest of the answers are wrong.
(a). X + 12 = 20 ( 12,8,20,0)
X= 20 -12
X= 8, so only 8 is the correct answer and rest are wrong.
Proof: lets take other given options into consideration
X= 12
X+12 =12+ 24 which is wrong because X+12 is already given as 20.
similarly,
X=20
X+12 = 20+12 = 36, which is wrong because X+12 is already given as 20.
X= 0
X+12 = 0+12 = 12, which is wrong because X+12 is already given as 20.
(b). P - 4 = 0 (4,-4,8,0)
P-4 = 0
P= 4, So only 4 will give the correct answer and not the other options.
P= -4 = -4 -4 = -8, which is wrong because P-4 is is already given as 0.
similarly,
P = 8 = 8-4 = 4, which is wrong because P-4 is is already given as 0.
P = 0, 0-4 = -4 , which is wrong because P-4 is is already given as 0.
(c). 2y - 3 = 7 (0,3,5,7)
2y = 7 + 3
2y = 10
y = 5, only 5 will satisfy this given equation and rest will be wrong,
y = 0
2y-3 = 7
2(0) - 3 = 7
-3 = 7 which is not correct as LHS and RHS must be same.
similarly,
y = 3
2y-3=7
2(3) - 3 =7
6-3 = 7
3=7 which is again wrong.
y = 7
2(7) -3 =7
14-3 = 7
11=7, which is wrong.
Therefore the given options for the correct answers is verified and the wrong answers are given as the proof.

0.5 g of salt is equal to how many milligrams?
Show all of your calculations.
Answer:
500 mg
Step-by-step explanation:
K H D B D C M (Kilo, Hecto, Deka, Base [meters, grams, etc.] Deci, Centi, Milli)
since you're using grams substitute G for B
K H D G D C M
you have 0.5 grams of salt, which will be G for grams. you want to convert it to milligrams, which is M. you will move the decimal over 3 spots in order to get from G to M, therefore you go from 0.5 grams to 500 milligrams. I hope this is helpful!

(c) Paul uses the function y = 7x + 30 to model the situation. What score does Paul’s model predict for 3 hours of homework?
(d) Describe what the number 30 in Part (c) mean in the context of the situation?
Answer:
(c) Paul's model predicts a score of 51 for 3 hours
(d) 30 represents the y intercept
Step-by-step explanation:
Given
[tex]y = 7x + 30[/tex]
Solving (c): What is y when x is 3
Substitute 3 for x in [tex]y = 7x + 30[/tex]
[tex]y = 7*3 + 30[/tex]
[tex]y = 21 + 30[/tex]
[tex]y = 51[/tex]
Solving (d): What does 30 represent
An equation is represented as:
[tex]y = mx + b[/tex]
Where
[tex]b = y\ intercept[/tex]
Compare: [tex]y = mx + b[/tex] to [tex]y = 7x + 30[/tex]
[tex]b = 30[/tex]
This implies that 30 represents the y intercept

Shape: Triangle
Dimension: 3x + 2, x^2 and 2x
[tex]x = 4[/tex]
Required
Determine if it has equal sides
To do this, we simply substitute 4 for x in the given dimensions
3x + 2
[tex]3x + 2 = 3 * 4 + 2[/tex]
[tex]3x + 2 = 12 + 2[/tex]
[tex]3x + 2 = 14[/tex]
x^2
[tex]x^2 = 4^2[/tex]
[tex]x^2 = 16[/tex]
2x
[tex]2x = 2 * 4[/tex]
[tex]2x = 8[/tex]
[tex]3x+2 \ne x^2 \ne 2x[/tex] for [tex]x = 4[/tex]
