Answer:
The answer is A. $1.35
Step-by-step explanation:
Two $10 bills are equal to $20.
Your change is $7.85
So if you subtract $7.85 from $20 you will come up with $12.15.
$12.15 is how much money you spend on mini burgers.
You can then divide how much money you spent with how many burgers you bought.
12.15 divided by 9 gives us 1.35. So each burger was $1.35.
I think the correct answer would be : (-8,3)

2/5 = y/100
40/100 = y/100
Y=40
Answer:
No. Remember, a right angle must have a 90 degree angle. We can find the lengths with the Pythagorean Theorem.
Step-by-step explanation:
Given the length 7, 10, and 12, we can assume that 12 is the hypotenuse (it is the longest length).
- we can use 7 and 10 interchangeably.
Fill in the equation, 
where c = 12, and a or b = 7 or 10.
To indicate if the given lengths would form a right angle, we can only input 7 or 10, not both.
Therefore,
or 
==> 49 + b^2 = 144 ==> <u>b= </u>
<u> ==> </u><u>9.746</u>
b= 9.7, not 10.
==> 100 + b^2 = 144 ==> <u>b = </u>
<u> ==> </u><u>6.633 </u>
b= 6.6, not 7.
Therefore, the lengths 7, 10, and 12, does NOT make a right triangle.
Hope this helps!
