If you would like to solve x% of 200 miles is 10 miles, you can calculate this using the following steps:
x% of 200 miles is 10 miles
x% * 200 = 10
x/100 * 200 = 10
x * 2 = 10 /2
x = 10/2
x = 5
Result: 5% of 200 miles is 10 miles.
Answer:
x = 9
Step-by-step explanation:
STEP 1: Find the dilation of RQ to VT
Dilation = 9:12
= 3:4 or 3/4
STEP 2: Apply that dilation to PR to UV
Expression: x-3:18
(<em>x-3 has to equal </em><em>3</em><em>/</em><em>4</em><em> </em><em>of</em><em> </em><em>18</em>)
18/3 = 6
x-3 = 6
x = 9
This is your final answer.
Hope this helped ^^

7 is just adding.
8 is counting by odd numbers.
9 is a rotation
Let the coordinates of the treasure be (x,y).
Let
![d_{1}](https://tex.z-dn.net/?f=%20d_%7B1%7D%20)
= distance from the rock to the treasure.
Let
![d_{2}](https://tex.z-dn.net/?f=%20d_%7B2%7D%20)
= distance from the tree to the treasure.
![d_{1} = \sqrt{(x\2 + (y-2)^2}](https://tex.z-dn.net/?f=%20d_%7B1%7D%20%3D%20%5Csqrt%7B%28x%5C2%20%2B%20%28y-2%29%5E2%7D%20)
![d_{2} = \sqrt{(16-x)^2 + (21-y)^2}](https://tex.z-dn.net/?f=%20d_%7B2%7D%20%3D%20%5Csqrt%7B%2816-x%29%5E2%20%2B%20%2821-y%29%5E2%7D%20)
We want
![\frac{ d_{1} }{ d_{2} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20d_%7B1%7D%20%7D%7B%20d_%7B2%7D%20%7D%20)
= 5/9 in order to locate the treasure.
Note that 5/9 = 0.556 (approx)

The correct answer is (7.6, 8.8)
Answer:
<h2>
A. 1 and 1
</h2><h2>
D. 6 and 1/6
</h2><h2>
E -4/7 and -7/4</h2>
Step-by-step explanation:
The question is incomplete. Here is the complete question.
Which pairs of numbers represent a number and its reciprocal?
A. 1 and 1
B. 2/3 and -3/2
C. 1/2 and 5
D. 6 and 1/6
E -4/7 and -7/4
Reciprocal of a number is simply 1 divided by such number. For example the reciprocal of a is 1/a where is any number.
Based on the definition, the following pair of numbers represent a number and its reciprocal
1 and 1
The reciprocal of 1 is 1/1 which is equal to 1
6 and 1/6;
Since I can divide 1 by 6 to get 1/6 , this means that 1/6 is the reciprocal of 6. The pair 6 and 1/6 therefore represent a number and its reciprocal.
-4/7 and -7/4
reciprocal of -4/7 will be 1/(-4/7) = 1 * 7/-4 = -7/4. This shows that -7/4 is the reciprocal of -4/7 hence -4/7 and -7/4 represents a number and its reciprocal.
