PLS HELP I BEG YOU ASAP! PLS Answer this! I only have 5 minutes PLS I BEG U!!!! I also the the price of each notebook hint:find the value of X

Answers

Answer 1

Answer: 2x+4=10

Step-by-step explanation:

because each notebook would cost $3 so 2 x 3 = 6 +4=10

Answer 2

Answer:

first

2x + 4 = 10

2x+4=10

Solve

Subtract

from both sides of the equation

2x+4=10

−

2x+4{\color{#c92786}{-4}}=10{\color{#c92786}{-4}}

2x+4−4=10−4

Simplify

Subtract the numbers

2x=6

Divide both sides of the equation by the same term

2x=6

\frac{2x}{{\color{#c92786}{2}}}=\frac{6}{{\color{#c92786}{2}}}

22x=26

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

x=3

Solution

Second one

6 = 10

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

x=\frac{5}{3}

x=35

Solution = 5/3

i hope these help to figure out the third sorry its all messed up it wouldnt let me do another way

The Big Time Band put on a community concert. A total of 1,236 people attended the concert. There were twice as many adults as children who attended the concert. How many adults attended the concert?

Answers

Answer:

412 adults

Step-by-step explanation:

Let the number of adults be x

Let the number of children be y

If a total of 1,236 people attended the concert, then;

x + y = 1236 .....1

If there were twice as many adults as children who attended the concert, then;

y = 2x

Substitute y = 2x into 1

x + 2x = 1236

3x= 1236

x = 1236/3

x = 412

Hence 412 adults attended the concert.

A school lunch costs $2.50. A monthly lunch pass costs $40.00. Which inequality represents the number x of lunches you must purchase for the monthly pass to be a better deal?

Answers

Answer:

The inequality 2.50x>40.00 represents the number of lunches needed to be purchased for the monthly lunch pass to be a better deal.

Step-by-step explanation:

Given that:

Cost of each lunch = $2.50

Cost of monthly lunch pass = $40.00

Number of lunches = x

For making the monthly pass a better deal, the cost of lunches should be greater than the cost of monthly lunches, therefore

Cost of lunch * Number of lunches > Cost of monthly lunch pass

2.50x > 40.00

Hence,

The inequality 2.50x>40.00 represents the number of lunches needed to be purchased for the monthly lunch pass to be a better deal.

Answer:

2.50x > 40.00

$2.50 times a number of lunches is greater than $40.

8

Answers

Answer:

Step-by-step explanation:

it's multiplied by 2 as you go to triangle 2

Answer:

x = 8

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{5}{10}[/tex] = [tex]\frac{4}{x}[/tex] ( cross- multiply )

5x = 40 ( divide both sides by 5 )

x = 8

Given 3,8,14,x+6,2x-3,25,32,50 are in ascending order , whose median is 18. Find the unknown terms.

Answers

because we know that the number in between x+6 and 2x-3 is 18, we can solve for x by doing (x+6+2x-3)/2=18. this simplifies to 3x+3=36, or x=11.

Answer:

C) 21

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

BracketsParenthesisExponentsMultiplicationDivisionAdditionSubtractionLeft to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

-3x + 40 = -23

Step 2: Solve for x

Isolate x term: -3x = -63Isolate x: x = 21

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: -3(21) + 40 = -23Multiply: -63 + 40 = -23Add: -23 = -23

Here we see that -23 does indeed equal -23.

∴ x = 21 is the solution to the equation.

In order for Josh to graph the solution to the inequality 4x - 2y > 6, which of the following steps does he need to use? Select all that apply.

Shade above the line.
Solve the inequality as y < 2x-3.
Draw the line y=2x-3 as a solid line.
Draw the line y=2x-3 as a dashed line.
Shade below the line.
Solve the inequality as y> 2x-3.

Answers

Solve the inequality as y < 2x-3.

Draw the line y=2x-3 as a dashed line.

Shade below the line.

Josh needs to follow the steps to draw the required inequality graph.

Solve the inequality y < 2x - 3 by solving for the x and y-interceptDraw the straight line y < 2x - 3 as a dashed line (since we have less than sign )Shade below the line. (Below the line are shaded for inequality sign that is "less than")

Inequality expressions are expressions that are not separated by an equal sign.

Given the inequality expression 4x - 2y > 6,

Dividing through by 2 will give:

4x/2 - 2y/2 > 6/2

2x - y > 3

Make y the subject of the formula

ill mark your question brainliest if u give me corect amswer

Answers

Answer:

7/13

Step-by-step explanation:

Let's call x= numerator

We know that :

Denominator= x+6

And

(numerator +2)/(denominator +2) = 3/5

(x+2)/(x+6+2)=3/5

(x+2)/(x+8)=3/5

(x+2)*5=(x+8)*3

5x+10=3x+24

2x=14

x=7

In the end

Numerator= x =7

Denominator=x+6 = 13

So the original number is 7/13

Answer:

N and P are equal to 48 degrees

Step-by-step explanation:

1. 3y^2=12y^2−144

2. Subtract 3y^2 from both sides

3. add 144 to both sides

4. 9y^2= 144

5. Divide both sides by 9

6. y^2 = 16

7. Take the square root of 16 ( which is y=±√16)

8. y = 4 or y = -4

Answer:

∠ N = ∠ P = 48°

Step-by-step explanation:

Δ KMP and Δ LJN are similar ( AA postulate ), then corresponding angles are congruent, that is

∠ P = ∠ N

12y² - 144 = 3y² ( subtract 3y² from both sides )

9y² - 144 = 0 ( add 144 to both sides )

9y² = 144 ( divide both sides by 9 )

y² = 16 ( take the square root of both sides )

y = [tex]\sqrt{16}[/tex] = 4

Then

∠ N = 3y² = 3(4)² = 3(16) = 48² = ∠ P
