Answer:

8 and 32

Step-by-step explanation:

(19)

x³ ÷ 3 - y ( substitute x = 3, y = 1 into the expression )

= 3³ ÷ 3 - 1

= 27 ÷ 3 - 1

= 9 - 1

= 8

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

(21)

12k - h² ( substitute h = 2, k = 3 into the expression )

= 12(3) - 2²

= 36 - 4

= 32

If a segment XZ joining two endpoints X[tex](x_1,y_1)[/tex] and Z[tex](x_2,y_2)[/tex] is divided by a point Y(x, y) externally in the ratio of m : n,

Coordinates of the point will be,

x - coordinates → [tex]\frac{mx_2-nx_1}{m-n}[/tex]

y - coordinates → [tex]\frac{my_2-ny_1}{m-n}[/tex]

If the coordinates of the endpoints X and Z are (1, 9) and (5, -11) respectively and the ratio in which a point Y divides the segment is 1 : 5,

(Since, XY : XZ = 1 : 4 therefore, XY : YZ = 1 : 5)

Therefore, coordinates of Y will be,

x- coordinates → [tex]\frac{1(5)-5(1)}{1-4}=0[/tex]

y-coordinates → [tex]\frac{1(-11)-5(9)}{1-5}=\frac{-56}{-4}=14[/tex]

Therefore, coordinates of Y will be [tex](0,14)[/tex].

-27

-19=1/4b

1/4

-4.7≥b

Answer:

b ≤ = -76

Step-by-step explanation:

8 – 1/4b ≥ 27

Subtract 8 on both sides

-1/4b ≥ 19

Times -4 on both sides

b ≤ -76

Answer:

If Adrian buys 2 more CDs, he will pay $56.

Adrian will pay $64 for eight CDs.

Step-by-step explanation:

So, we already know that 5 CDs costs $40. That means that we can use this information to figure out how much 1 CD costs.

40 ÷ 5 = $8 per CD

Now that we know that each CD costs $8, we know that if Adrian buys 2 more CDs, then he will pay $16 ($8 x 2) more than his current price.

$40 + $16 = $56.

If Adrian buys 2 more CDs, he will pay $56.

Now, in order to find out how much 8 CDs costs, we just need to divide $8 by 8.

$8 x 8 = $64

Therefore, Adrian will pay $64 for eight CDs.

I hope this helps! :)

Answer:

y=3

Step-by-step explanation:

6=2(y+2)-4

6=2y+4-4

6-4+4=2y

6=2y

3=y

The answer you are looking for is y=3.

Solution/Explanation:

First, writing out the problem,

6=2(y+2)-4.

Next, using the Distributive Property for 2(y+2), which is 2y+4,

6=2y+4-4.

Now, canceling out the 4, since 4-4=0,

6=2y+0, or 6=2y.

Finally, dividing both sides by 2,

6/2=2y/2.

6/2=3.

2y/2=y.

3=y, or y=3.

So, therefore, the final answer is y=3.

I hope that this has helped answer your question. Good day to you.

Answer:

y = [tex]\frac{ac}{a-b-c}[/tex]

Step-by-step explanation:

Given

y(a - b) = c(y + a) ← distribute parenthesis on both sides

ay - by = cy + ac ( subtract cy from both sides )

ay - by - cy = ac ← factor out y from each term on the left side

y(a - b - c) = ac ← divide both sides by a - b - c

y = [tex]\frac{ac}{a-b-c}[/tex]

The value of y is ac/ (a-b-c)

An equation in math is an equality relationship between two expressions written on both sides of the equal to sign.

For example, 3y = 16 is an equation.

Given equation:

y(a-b)=c(y+a)

Now, using distributive property

ay-by = cy + ac

ay-by-cy = ac

y(a-b-c)=ac

y= ac/ (a-b-c)

Hence, the value of y is ac/ (a-b-c).

4^2 * 4^8 = B)4^10

Step-by-step explanation:

When multiplying numbers with exponents, you will always add the exponents together. Therefore, 2+8=10 which is 4^10. You can also simplify the numbers and multiply them together. For example, 4^2=16 and 4^8=65,536 and when u multiply those numbers you get 1,048,576. The one that matches is 4^10=1,048,576.

Answer:

1 hour and 29 minutes

Step-by-step explanation:

4:50 pm to 6:00 pm is 1 hour and 10 minutes.

6:00 pm to 6:19 pm is 19 minutes.

1 hour and 10 minutes + 19 minutes = 1 hour and 29 minutes.

Explanation:

Let's find out how long Kajal spoke on the phone.

4:50 + 10 mins = 5:00

5:00 + 60 mins = 6:00

6:00 + 19 mins = 6:19

To find the total time between 4:50 + 6:19, we add the distances.

10 mins + 60 mins + 19 mins = 89 mins

Thus, Kajal spoke on the phone for 89 minutes.
