You'll most likely have to use the quadratic formula to find your answer.
Answer:
y=8/3
Step-by-step explanation:
x=y-3
4x+2y=2
4(y-3)+2y=2
4y-12+2y=2
6y-12=2
6y=16
y=16/6=8/3
Answer: About 12 of those 60 students are boys.
To find the percent, you'll convert 20% to a decimal.
20 / 100 = 0.2
Then, multiply 60 by 0.2
0.2 × 20 = 12
That's one way, another way is:
Convert 20% to a fraction.
20% = 1/5
Then multiply 60 by 1/5.
60 × 1/5 = 60/5
Lastly, divide 60 by 5
60 / 5 = 12.
Hence, 12 is the answer.
