Answer:
Step-by-step explanation:
-9x + y = 16
12x + y = -5
12x + y = -5
9x - y = -16
21x = -21
x = -1
9 + y = 16
y = 7
(-1,7)
You missed one final step, no worries! When finding the percent off, subtract the value you got after dividing the price after discount by the initial price from 100.
So: 100 - 65 = 35
35% off
Hope this helps!
Considering the opposite of the rational number -1/2, the location of the snail is represented by the number 1/2.
<h3>What is the missing information?</h3>
This problem is incomplete, but researching it on a search engine, we have that:
- The fish is located at -1/2 feet.
- The snail is located at the opposite location of the fish.
<h3>What is the opposite of a rational number?</h3>
The opposite of a rational number a is given by -a, that is, it is the number with the opposite signal.
Hence, the <u>opposite of -1/2 is 1/2</u>, and the location of the snail is represented by the number 1/2.

The answer is 11/36
2/12 chance of rolling fours
because there are 2 sides containing a four on both dice combined and 12 sides in total.
Doubles mean you have to roll the same number simultaneously so let’s say we want to calculate the probability for double ones: then it’s 1/6 on the first dice for a one, and 1/6 on the second dice to land on a one as well.
I personally like to imagine a box like this:

If you have one dice then it’s just a random segment on one of the lines. If you want the specific result from two dice then you want two specific segments which is also the 1 specific tile out of 36 (6 width times 6 height). So you multiply.
1/6 * 1/6 = 1/36 chance to roll double of ones
And 1/36 chance to roll double twos, threes, fours, fives, and sixes. But we don’t count the double fours because any four will do. So:
1/36 * 5 = 5/36
So for the probability of either doubles or containing a four is the probability of doubles of either number plus the probability of either dice being a four:
5/36 + 2/12 =
5/36 + 6/36 =
11/36
