Answer:
3, 50, 2
Step-by-step explanation:
By multiplying all terms by 5, we are trying to remove the fraction on the left hand side. On the right hand side of the equation, expand the bracket by multiplying 5 to each term in the bracket.
3(n +25)= 5(10) +5([tex] \frac{2}{5} n[/tex])
3(n +25)= 50 +2n
To find the value of n, expand the bracket on the left hand side:
3(n) +3(25)= 50 +2n
3n +75= 50 +2n
Bring all n terms to one side, constants to the other:
3n -2n= 50 -75
n= -25

Answer:
1. Vertical angles. X = 128º
2. The two angles labeled make up a linear pair & are supplementary, meaning they add up to 180º.
So:
7x + (x+20) = 180
Solve for x:
7x + (x + [20-20]) = 180 - 20
7x + (1)x = 160
8x = 160
X = 20
3. The two angles are complementary, meaning they add up to 90º.
So:
X + 35 = 90
Solve for x:
X + (35-35) = 90 - 35
X = 55
4. the two angles are complementary, and add up to 90º.
So:
4x + 2x = 90
Solve for x:
6x = 90
6x/6 = 90/6
X = 15.
5. Vertical angles, so they are equal in measure.
So:
75 = 4x - 25
Solve for x:
75 + 25 = 4x (-25 + 25)
100 = 4x
100/4 = 4x/4
X = 25.
6. The 3 angles all add up to 180º. they are supplementary.
So:
75 + x + (3x + 5) = 180
Solve for x:
(75 - 75) + x + (3x + 5) = 180 - 75
X + (3x + 5) = 105
X + 3x + (5-5) = 105 - 5
(1) x + 3x = 100
4x = 100
4x/4 = 100
X = 25
7. The 2 angles shown in the picture add up to 180º & are supplementary.
So:
x + (2x - 21) = 180
Solve for x:
X + (2x [-21 + 21]) = 180 - 21
(1)x + 2x = 159
3x = 159
3x/3 = 159/3
X = 53.

1 over 12
1 ninth
3 sevenths
3 forth
Answer:
c wich is sevenths
Step-by-step explanation:
The probability the teacher that chooses a girl to write the date on the board is :
C) 3 sevenths.
"Probability"
Given:
Boys =12
Girls =9
Total number of students = 12 + 9 = 25.
So the probability of choosing a girl is = n(girl) / n(all students) = [tex]\frac{9}{25}[/tex]
This is close to 3 sevenths.

The sides of a 30°-60°-90° triangle are in the ratio 1:√3:2
The length of the side opposite the 90° angle is 10,
so the length of the side opposite the 30° angle is 5

Describe the transformation of f(x) = sin x to g(x) = sin x - 17 ?
Answer:
f(x) underwent a downward vertical translation to get g(x)
Step-by-step explanation:
here, we want to describe a transformation
Looking at the two equations, we can notice that the difference between the two is the -17
Practically, we have this difference as 17 subtracted from the second equation
what this mean is that there is a downward vertical translation of the first graph by 17 units to get the second graph

Find the equation of a line that passes through the point (0,4) and has a gradient of 2.
Leave your answer in the form y = mx + c
Answer:
y = 2x + 2
Step-by-step explanation:
y = mx+c
m = slope
c =y -intercept
Therefore, the required equation is:
y = 2x + c
Putting the point (0,4) in it as it lies on a line, we get:
4 = 2 + c
Therefore:
c = 2
So, y = 2x + 2
Brainlist pls!
The equation of a line that passes through the point (0,4) and has a gradient of 2 is y = 2x + 4
Equation of a lineThe equation of a line in point-slope form is expressed as:
y = y1 = m(x-x1)
Given the following
Slope m = 2
(x1, y1) = (0, 4)
Substitute
y - 4 = 2(x- 0)
y -4 = 2x
y = 2x + 4
Hence the equation of a line that passes through the point (0,4) and has a gradient of 2 is y = 2x + 4

CAN SOMEONE PLZ HELP ME WITH THIS 1 QUESTION!?!
no because you wouldn't switch the fraction upside down to make it opposite.
Answer:
What Doug probably means to say is that the reciprocal of -2/5 is 5/-2. So, by this definition, Doug would be correct. However, you would not usually call it the "opposite" of a number, rather, the reciprocal.
The numbers are reciprocals of the other as their product is equal to one "-2/5 * 5/-2 = 1"

When a standard die is rolled, find the probability of getting a. 5 b. A number larger than 2 c. An odd number.
Answer:
P(getting a 5)=[tex]\frac{1}{6}[/tex]
P(number larger than 2)=[tex]\frac{2}{3}[/tex]
P(numbers which are odd) =[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
When a standard die is rolled, we get sample space as {1,2,3,4,5,6}
So, let's use formula
P(E)=[tex]\frac{outcomes favorable to event E}{Total number of outcomes}[/tex]
For part A:
Event is getting a 5.
So, out of 6 samples , we get one 5 as outcome
So,
P(getting a 5)=[tex]\frac{1}{6}[/tex]
For part B:
The numbers larger than 2 are {3,4,5,6}
So, p(number larger than 2)=[tex]\frac{4}{6} =\frac{2}{3}[/tex]
P(number larger than 2)=[tex]\frac{2}{3}[/tex]
For part C:
The numbers which are odd are {1,3,5}
So, p(numbers which are odd)=[tex]\frac{3}{6 } =\frac{1}{2}[/tex]
P(numbers which are odd) =[tex]\frac{1}{2}[/tex]

Hayley took a total of 9 quizzes over the course of 3 weeks.After attending 7 weeks of school quater,how many quizzes will hayley have taken in total
Answer:
21 quizzes
Step-by-step explanation:
3 quizzes per week 9÷3=3
7 weeks = 3×7 so 21 quizzes
Answer:
21 quizzes
Step-by-step explanation:
What we know:
- Hayley takes 9 quizzes in 3 weeks
What we want to find:
- The number of quizzes Hayley would've taken after 7 weeks
We need to first find the number of quizzes Hayley would take in 1 week and then multiply that number by 7. To find the number of quizzes per week, divide 9 by 3:
9÷3=3
Therefore, every week, Hayley takes 3 quizzes.
Now, we multiply 3 by 7:
3×7=21
Therefore, after attending 7 weeks of school, Hayley would've taken 21 quizzes in total.
