Answer:

First question is 109

Second question is 45, but I guess it's a typo with 145.

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

(in this case, Y would equal 4 since the angles are not negative lol)

9. Plug 4 into the equations

10. Compare each answer to see if they are equal

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

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.

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

-y > -2x + 3

y < 2x -3

For Josh to plot the inequality graph of y < 2x - 3, he needs to follow the process;

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

So

(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:

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.

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.

Answer:

8

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

Answer:

B

Step-by-step explanation:

The equivalent expression is [tex]16x^{8}[/tex]. So, the correct option is B.

Given:

The given expression is:

[tex]4x^2\sqrt{5x^4}3\sqrt{5x^8},x\neq 0[/tex]

To find:

The equivalent expression.

Explanation:

We have,

[tex]4x^2\sqrt{5x^4}3\sqrt{5x^8}[/tex]

On simplification, we get

[tex]=4x^2(x^2\sqrt{5})3(x^4\sqrt{5})[/tex]

[tex]=(4\times 3)(x^{2+2+4})(\sqrt{5}\times \sqrt{5})[/tex]

[tex]=12(x^{8})(5)[/tex]

[tex]=16x^{8}[/tex]

Therefore, the correct option is B.
