Answer:

27 years old

Step-by-step explanation:

Let Alvin's age be x and Elga's age is y:

y - x = 15

x + y = 27

2y = 42 (use elimination method)

y = 21

x = 6 (plug it back into either equation)

Therefore Alvin is 6 and Elga is 27

Answer:

-2

Step-by-step explanation:

2(8) - 3(6)

16 -18 = -2

Answer:

-2

Step-by-step explanation:

If y = 8, then 2y = 8 times two, so 2y = 16

If k = 6 then 3k = 6 times 3, so 3k = 18

16 - 18 = -2

Answer:

subtract 14 from each side

7=7x

x=1

Step-by-step explanation:

plz brainliest!

The required solution to the equation 21 = 14 + 7x is x = 1.

An equation is a mathematical statement that shows the equality between two expressions. It consists of an equal sign (=) separating the two sides of the equation.

To solve for x, we can first subtract 14 from both sides of the equation:

21 - 14 = 14 + 7x - 14

Simplifying:

7 = 7x

Next, divide both sides of the equation by 7:

7/7 = 7x/7

1 = x

Therefore, the solution to the equation 21 = 14 + 7x is x = 1.

Answer:

0.333n + 28 ; 33.3 ; $41.653

Step-by-step explanation:

For the best fit line :

The slope of the graph :

Drawing a right angled triangle at any point on the best fit line :

Gradient = (y2 - y1) / (x2 - x1)

Gradient = (45 - 30) / (50 - 5)

Gradient = 15 / 45

Gradient = 0.333

Intercept :

Where best fit line crosses the y - axis = 28

b = 0.333n + 28

The extra cost of each extra call made made is the slope of the graph :

$0.333 = 33.3 cents

Estimated cost of 41 calls

b = 0.333(41) + 28

b = $41.653

Kindly note that, the values used were obtained from a graph which isn't lined, therefore values taken may not be very accurate.

Answer:

20% because if there's six different chocolates she likes and if she picks random thers a possibility of it

x^2+2x-24 is the correct answer

Answer:

B

Step-by-step explanation:

The slope is 4/1 which equals 4

the y int is 2

this gives us 4x+2

the line is dotted which mean there is no equal sign with the inequality

The shaded area is above the line, meaning y is greater

Step-by-step explanation:

Since it is a right-angled triangle,

we have a² + 5² = 13². (Pythagoras' Theorem)

=> a² = 13² - 5² = 144, a = 12. (C)

Hey there!

The answer to your question is £1729.

To solve this equation, first we find how much is left. 100% - 9% = 91 %. That means that the new price is 91% of the old price. So, we can do 0.91 x 1900, and we get 1729.

Therefore, the new price is  £1729.

Hope it helps! Have a great day, and good luck!

A holiday costs £1900.The price after a 9% discount is £1729

For better understanding , check the calcualtion to find out price after discount below.

A holiday costs £1900. we need to find out the price after a 9% discount

We are given with 9% discount. find out the discount amount from the cost .

Discount amount = original cost * the discount percentage

discount amount

[tex]1900 \cdot 9percent\\\\1900 \cdot \frac{9}{100} \\171[/tex]

Discount amount is £171

Now subtract the discount amount from the original cost

Final cost after discount is

[tex]1900 - 171 \\1729[/tex]

A holiday costs £1900.The price after a 9% discount is £1729
