ANSWER:

<u>On solving equation, we get</u>

3x - y = 12
3x = 12 + y
x = 12 + y/3 ...(1)

<u>We have to find</u>,

8^x/2^y
2^3x/2^y
2^3x - y

<u>Plugging the value of x</u>,

2^3(12 + y/3) - y
2^12 + y - y
2^12
4096

Hence, The value of 8^x/2^y is 4096.

Divide the fractions and simplify the answer 1/2 5/8

NeTakaya

To solve this let our write this fraction in terms.
$\frac{1}{2} 
$ / $\frac{5}{8}$

So now let change this problem as a multiplication problem. To change this to multiplication problem we have to flip our second term

$\frac{1}{2} * \frac{8}{5}$

So, now let's simplify the terms. So we get
$\frac{4}{5}$

Thus this is our final answer.

Helen [10]

Answer: 6 1/5 miles

Step-by-step explanation:

Here's the complete question:

On Tuesday, Stacy rode her bicycle 1 3/4 miles from her house to the supermarket. She walked 1/4 of a mile while at the supermarket. She rode her bicycle a different way home that was 2 1/5 miles long. How many miles did Stacy ride her bicycle on Tuesday.

The number of miles that Stacy ride her bicycle on Tuesday will be the addition of her distance from her house to the supermarket and back to her house from the supermarket. This will be:

= Distance to supermarket = 1¾ + ¼ = 2 miles

Distance from supermarket = 2 + 2 1/5 = 4 1/5 miles

Total distance = 2 + 4 1/5 = 6 1/5 miles

Heeeeellllppp PLEASE!!!! 20 POINTS!!!

Scilla [17]

The formula of a midpoint:

$\left(\dfrac{x_1+x_2}{2};\ \dfrac{y_1+y_2}{2}\right)$

D is midpoint of TR.

We have T(-2a, 0) and R(-2b, 2c). Substitute:

$x=\dfrac{-2a+(-2b)}{2}=\dfrac{-2a-2b}{2}=\dfrac{2(-a-b)}{2}=-a-b\\\\y=\dfrac{0+2c}{2}=\dfrac{2C}{2}=c$

<h3>Answer: b. (-a - b, c)</h3>
