Answer:
165 boys
Step-by-step explanation:
we have:
462=a+b
a=girls
b=boys
a=132+b
462=132+b+b
462=132+2b
462-132=2b
b=165 = boys
Answer: There are 165 boys
[tex]b = 165[/tex]
Step-by-step explanation:
Let's call b the number of boys and call g the number of girls in the class.
Then we know that:
There are 462 students. This means that:
[tex]b + g = 462[/tex]
We also know that there are 132 more girls than boys, this means that:
[tex]g = b + 132[/tex]
Now we substitute the second equation in the first and solve for b.
[tex]b + (b + 132) = 462[/tex]
[tex]2b = 462-132[/tex]
[tex]2b = 330[/tex]
[tex]b = \frac{330}{2}[/tex]
[tex]b = 165[/tex]
