Answer:
23 males and 12 females
Step-by-step explanation:
x = # of females
y = # of males
x + y = 35
x + x + 11 = 35
2x + 11 =35 (SUBTRACT 11 FROM BOTH SIDES)
2x = 24 (DIVIDE BOTH SIDES BY 2)
x = 12 females
x + y =35
12 + y = 35 (SUBTRACT 12 FROM BOTH SIDES)
y = 23 males
23 males + 12 females = 35 students
Divide 31 by 50 and that will give you .62 move the decimal point two places to the right and that gives you 62%. :)
For math- The difference between a value of a variable and another variable which usually ends up to be the variables mean
The numerator and denominator must be polynomials so
the answer to your question is - 7x / x^2 ( the last one on the right)
