After 4 new students joined a dass, the class had 32 students.
Which equation can be used to find n, the number of students in the class before the 4 new students joined?

Answers

Answer 1
32-4=n

steps- there are 4 students that joined and the class had 32 students including the ones that joined. You would then subtract 32 and 4 and your n would be what it would equal. which n would equal 28

please tell me the step process of this btw this is 7th-grade math its angle measurements I'm confused about the process pls help.

Answers

Answer:

Angle BDA is 90°

(2x + 3) + 55 = 90

2x + 3 + 55 = 90

2x + 58 = 90

2x = 90 - 58

2x = 32

x = 32/2

x = 16

Hence,

x=16

x=16Angle BDA is 90°.

Last night, 4 friends split the dinner bill evenly. Each friend paid $12.75 and left the same amount for a tip. The bills total was $61. What equation could describe the situation?

Answers

Answer: 4 * (12.75 + x) = 61

Step-by-step explanation:

Each of the 4 friends paid $12.75 so that is:

= 4 * 12.75

Assuming the tip is denoted as x it would be:

= 4x

Putting them together is:

4 * (12.75 + x) = 61

Solving the equation would give:

4 * (12.75 + x) = 61

51 + 4x = 61

4x = 61 - 51

x = 10/4

x = $2.50

When solving the equation, which is the best first step to begin to simplify the equation?

A sum of money is to be divided among three girls, Anna, Barbara and Chrissy in the ratio 5 : 3 : 2. If Barbara received $400 less than Anna, calculate the amount of money each girl received.

Answers

Answer:

Anna received $1000

Barbara received $600

Chrissy received $400

Step-by-step explanation:

Let us solve the problem

∵ The ratio of Anna, Barbara, and Chrissy is 5: 3: 2

∵ Barbara received $400 less than Anna

→ That means Anna - Barbara is 400, find the difference between their ratio

∵ The difference between their ratio = 5 - 3 = 2  

→ By using the ratio method

→  Anna  :  Barbara  : difference

→  5        :  3              :  2

→  A        :  B             :  400

→ By using the cross multiplication

A × 2 = 5 × 400

∴ 2A = 2000

→ Divide both sides by 2

A = 1000

Anna received $1000

∵  B × 2 = 3 × 400

∴ 2B = 1200

→ Divide both sides by 2

B = 600

Barbara received $600

Let us use the ratio between Anna and Chrissy to find the amount of Chrissy

→  Anna  :  Chrissy

→  5        :   2

→  1000  :   C

→ By using cross multiplication

5 × C = 2 × 1000

∴ 5C = 2000

→ Divide both sides by 5

C = 400

Chrissy received $400

Answers

Given:

An exterior angle of a triangle = 2x+30°

Two opposite interior angles are 33° and 41°.

To find:

The value of x.

Solution:

According to the exterior angle thereom, the exterior angle of a triangle is equal to the sum of opposite interior angles.

Using exterior angle theroem, we get

[tex](2x+30)^\circ=33^\circ+41^\circ[/tex]

[tex](2x+30)^\circ=74^\circ[/tex]

[tex](2x+30)=74[/tex]

On further simplification, we get

[tex]2x=74-30[/tex]

[tex]2x=44[/tex]

[tex]x=\dfrac{44}{2}[/tex]

[tex]x=22[/tex]

Therefore, the value of x is 22.

What is an equation of the line that passes through the points (-6, -3) and
(-3, -5)?

Answers

Answer:

y = − 2 /3 x − 7

Step-by-step explanation:

Use the slope formula and slope-intercept form  y = m x + b  to find the equation.

❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤

Hey buddy ....

I really appreciate God to give me this chance to help u.

Let's see what to do...

-----------------------------------------------------------

First we need to find the slope of the line using this equation :

Suppose a = ( - 6 , - 3 ) , b = ( - 3 , - 5 )

[tex]slope = m = \frac{y(b) - y(a)}{x(b) - x(a)} \\ [/tex]

Just need to put the coordinates in the equation:

[tex]slope = \frac{ - 5 - ( - 3)}{ - 3 - ( - 6)} \\ [/tex]

[tex]slope = \frac{ - 5 + 3}{ - 3 + 6} \\ [/tex]

[tex]slope = \frac{ - 2}{ - 3} \\ [/tex]

[tex]slope = \frac{3}{2} \\ [/tex]

====================================

We have this equation as the point-slope form of the linear functions :

[tex]y - y(one \: \: of \: \: the \: \: given \: \: points) = (slope) \times ( \: x - x(o \: o \: f \: t \: g \: p) \: ) \\ [/tex]

Now just need to put the slope and one the given points ( a or b ) in the above equation:

I like to use a ( you can use b bro )

[tex]y - ( - 3) = \frac{3}{2} \times (x - ( - 6) \: ) \\ [/tex]

[tex]y + 3 = \frac{3}{2} \times (x + 6) \\ [/tex]

[tex]y + 3 = \frac{3}{2} x + 9 \\ [/tex]

Subtract sides 3

[tex]y + 3 - 3 = \frac{3}{2} x + 9 - 3 \\ [/tex]

[tex]y = \frac{3}{2} x + 6 \\ [/tex]

And this is the equation of the line.

So we're done.....

Step-by-step explanation:

y = 180 ‐ 76 ‐ 2x

y = 104 ‐ 2x

5x ‐ 2 + y = 180 ( linear pair)

5x‐2+104‐2x = 180 ( y = 104 ‐ 2x)

3x+102=180

3x=180‐102

x=78/3

x=26
