Assuming the question is: '15 is 250% of what number'.
We can write an equation.
'is' indicates an equal sign
'of' indicates multiplication
'what number' indicates an unknown number we can call 'x'
So we have:
15 = 250% * x
or
15 = 2.5x
Divide 2.5 to both sides:
x = 6
B is the answer to your question
Answer:
y = -1x + 2
Step-by-step explanation:
We need to find y = mx + b
Use the following equation

Plug in the values
= 
We have found the slope(m) which is -1
We have to find y-int b
Plug in any given x,y into the slope formula
-1 = -1(3) + b
-1 = -3 + b
2 = b
At last the formula is
y = -1x + 2
Answer:
The answer would be 10.72
Step-by-step
You already have two side lengths so you use those to find the 3rd length
