Let's say the original price was "x", thus "x" is the 100%, and we know that 15 is 80% of that, thus
Answer:
-16
Step-by-step explanation:
Represent the number by n.
Then:
8(n + 18) = 16
Performing the indicated multiplication, we get:
8n + 144 = 16
Subtracting 144 from both sides results in 8n = -128.
Dividing both sides by 8: n = -128/8 = -16
The number was -16.
It is a 45-45 - 90 triangle (as the right angle is split in half for the outer one)
In this case, x is in the hypotenuse. The side lengths follow the 1, 1, √2 formula.
If 1 = 3, then:
3 x √2 = Answer
Answer = 3√2
