Luis walked one-eighth of the distance to school. What part of distance to school does he still need to walk?

klio [65]

<span>Total Distance = x
Luis walked one-eighth of x = x(1/8) = x/8
He still need to walk = Total Distance - Distance covered
He still need to walk = x-x/8
He still need to walk = (8x-x)/8

He still need to walk = 7x/8
He still need to walk = x(7/8)
He still need to walk seven-eighth of the total distance.

Answer:

See explanation

Step-by-step explanation:

Given the equation $3x-4y=12$

A. Create the table of values for at least 4 points.

When $x=0,$

$3\cdot 0-4y=12\\ \\-4y=12\\ \\y=-3$

When $x=2,$

$3\cdot 2-4y=12\\ \\-4y=12-6\\ \\-4y=6\\ \\y=-1.5$

When $x=4,$

$3\cdot 4-4y=12\\ \\-4y=12-12\\ \\-4y=0\\ \\y=0$

When $x=6,$

$3\cdot 6-4y=12\\ \\-4y=12-18\\ \\-4y=-6\\ \\y=1.5$

When $x=8,$

$3\cdot 8-4y=12\\ \\-4y=12-24\\ \\-4y=-12\\ \\y=3$

Thus, the table is

$\begin{array}{cc}x&y\\0&-3\\2&-1.5\\4&0\\6&1.5\\8&3\end{array}$

B. Use the table of values to graph the line on the coordinate plane. Plot given points and connect them with the straight line (see attached diagram).

There are approximately 40,000 people that live in a city. A sample of 20,000 people from that city are asked and 8,000 live in

Archy [21]

Answer:

16,000 people

Step-by-step explanation:

Let's write a ratio

8,000:20,000

Let's write another ratio

x:40,000

We can write a percent proportion.

$\frac{8,000}{20,000} =\frac{x}{40,000}$

We can see that the relationship between the denominators is multiplied by 2 so that means the relationship between 8,000 and x is x is 2 times greater than 8,000

Let me know if you have any questions.
