Answer: a=25
Explanation: I am assuming you are looking for “a” so if you heard the method of 45, 45, 90 it helps you solve it. So by the 45 being across from 25 makes the 45 across a 25 as well, hope this was what you were looking for…
The answer is y=3x-4 and here are the steps
C because scientific notation has to be number between 1-10
Equation
Y=P%*X
Y= 25%*75
Converting percent to decimal:
p = 25%/100 = 0.25
Y = 0.25 * 75
Y = 18.75
