A grid shows the positions of a subway stop and your house. The subway stop is located at (7, -6) and your house is located at (

Yuri [45]

So the distance between subway stop and house is 19 units

Step-by-step explanation:

The distance formula will be used to calculate the distance between home and subway.

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Here (x1,y1) are the coordinates of first point

and

(x2,y2) are the coordinates of second point

Given

(x1,y1) = (7, -6)

(x2,y2) = (-9,5)

Putting the values in the formula

$d=\sqrt{(-9-7)^2+(5-(-6))^2} \\=\sqrt{(-16)^2+(5+6)^2} \\=\sqrt{256+(11)^2}\\=\sqrt{256+121}\\=\sqrt{377}\\=19.41\ units$

Rounding off to nearest unit gives us 19.

So the distance between subway stop and house is 19 units

Amy received a $80 gift card for a coffee store. She used it in buying some coffee that cost $8.24 per pound. After buying the c

SVEN [57.7K]

Answer:

5 pounds

Step-by-step explanation:

Given that:

Amount of gift card = $80

Cost of coffee per pound = $8.24

Amount left in the card = $38.80

To find:

Number of pounds of coffee bought = ?

Solution:

Let the number of pounds of the coffee bought = $x$ pounds

Cost of 1 pound = $8.24

Cost of $x$ pounds = $8.24 $\times x$

Writing the equation as per question statement:

$80 - 8.24x = 38.80\\\Rightarrow 80 - 38.80 = 8.24x\\\Rightarrow 8.24x = 41.2\\\Rightarrow x = \dfrac{41.2}{8.24}\\\Rightarrow \bold{x = 5\ pounds}$

Therefore, 5 pounds of coffee was bought.

15+9=? (5+3) What number is missing from the expression?

Airida [17]

Answer:

<h3> $\boxed{ \boxed{ \bold{ \mathsf{3}}}}$ </h3>

Step-by-step explanation:

Let the missing number be 'x'

⇒ $\mathsf{15 + 9 = x(5 + 3)}$

Distribute x through the parentheses

⇒ $\mathsf{15 + 9 = 5x + 3x}$

Swap the sides of the equation

⇒ $\mathsf{5x + 3x = 15 + 9}$

Add the numbers

⇒ $\mathsf{5x + 3x = 24}$

Collect like terms

⇒ $\mathsf{8x = 24}$

Divide both sides of the equation by 8

⇒ $\mathsf{ \frac{8x}{8} = \frac{24}{8} }$

Calculate

⇒ $\mathsf{x = 3}$

Hope I helped!

Best regards!
