B) 25%
C) 33%
D) 50%

Answers

Answer 1

Answer:

Answer:

The answer is the option C

$33\%$

Step-by-step explanation:

we know that

$\$150$ ------> represent the $100\%$

by proportion

Find what percent has the price increased

$(100)/(150)(\%)/(\$)=(x)/(200-150)(\%)/(\$) \n \nx=(200-150)*100/150\n \nx=50*100/150\n \nx=33.33\%$

Answer 2

Answer: There is a formula to figure out questions like this:

The price difference/ the original price and times the whole equation by 100 (to get the percentage).

> ($50/$150) x 100 = 33% (rounded)

Answer:

x=9

Step-by-step explanation:

combine like terms

$4+6x+5=7x$

4+5=9

9+6x=7x

to get 6x with 7x subtract 6x from both sides as its positive

6x-6x=0

7x-6x=x

9=x

x=9

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 (-9, 5). What is the distance, to the nearest unit, between your house and the subway stop?

Answers

Answer: 19 units

Step-by-step explanation:

Given: The subway stop is located at (7, -6) and house is located at (-9, 5).

The distance formula to find distance between $(x_1,y_1)\ and (x_2,y_2)$ is given by :-

$d=√((x_2-x_1)^2+(y_2-y_1)^2)$

Therefore, the distance between house(-9, 5) and the subway stop(7, -6) is given by :-

$d=\sqrt{(7-(-9))^2+(-6-5)^2\n\n\Rightarrow\ d=√((16)^2+(-11)^2)}\n\n\Rightarrow\ d=√(256+121)\n\n\Rightarrow\ d=√(377)\n\n\Rightarrow\ d=19.4164878389\approx19\ units$
