Ratios can be described in different ways, if you were given a fraction such as 2/4 then we would put in 3 ways like 2/4, 2:4, and 2 to 4. So basically in any rule with fractions or anything else like that you'd have to explain it in 3 ways like my example shows.

Hopefully this helped. :)

Answer: x = 8

(the correct answer was not provided as an option)

<u>Step-by-step explanation:</u>

$log_2(x-6)+log_2(x-4)=log_2(x)\\\\log_2[(x-6)(x-4)]=log_2(x)\\\\(x-6)(x-4)=x\\\\x^2-10x+24=x\\\\x^2-11x+24=0\\\\(x-3)(x-8)=0\\\\x=3\qquad x=8\\\\\\\text{The term after the log symbol (inside the parenthesis) must be greater than 0!}\\\\Check:\\3-6>0\ \text{FALSE --- so 3 is not a valid solution}\\\\8-6>0\ \text{TRUE}\\8-4>0\ \text{TRUE}\\8>0\ \text{TRUE --- 8 is a valid solution because it is true for all}$

If someone ran 14.6 miles from their house and then they are now 9.8 miles from their house and finally they are 5.3 miles away

elixir [45]

Answer:

<u>10.1 miles</u> far is their house.

Step-by-step explanation:

Given:

If someone ran 14.6 miles from their house and then they are now 9.8 miles from their house and finally they are 5.3 miles away.

Now, to find the distance is far from their house.

14.6 miles distance they ran from their house.

So, they are far from house = $14.6\ miles.$

Then, 9.8 miles they are from their house.

So, they are far from house = $14.6-9.8\ miles=4.8\ miles.$

And, finally 5.3 miles away from their house.

So, now they are far from house = $4.8+5.3=10.1\ miles.$

Therefore, 10.1 miles far is their house.

navik [9.2K]

Answer:

Number of vans = 7 students

Number of buses = 60 students

Step-by-step explanation:

Let

Number of vans = x

Number of buses = y

2x + 11y = 674 (1)

6x + 14y = 882 (2)

Multiply (1) by 3

6x + 33y = 2,022 (3)

6x + 14y = 882 (2)

Subtract (2) from (3)

33y - 14y = 2,022 - 882

19y = 1,140

y = 1,140 / 19

= 60

y = 60 students

Substitute y = 60 into

2x + 11y = 674 (1)

2x + 11(60) = 674

2x + 660 = 674

2x = 674 - 660

2x = 14

x = 14/2

= 7

x = 7 students
