Question

Stable High School has a total of 112 boys and girls who play sports. If the number of girls, g is 16 more than twice the number of boys, b, how many girls play sports at this high school?
Which system of equations would help you solve this problem?

b + g = 112
b = 2g + 16

b + g = 112
g = 2b + 16

b − g = 112
b = 2g − 16

None of the systems above would solve this problem

Answer 1

ok, so it's saying that boys and girls together would make 112 students total, so off the bat we can get the first part down. Do you know what it is?

Answer 2

B

Answer 3

yup

Answer 4

remember to see that they tried to trick you with A and B being similar.

Answer 5

Because it says G = twice as many boys so equation B has b= 2g + 16 which is what we were lookin for right?

Answer 6

Yes they mixed the simplified part right?

Answer 7

cedric if the number of girls is twice the number of boys you agree that g=2b . right?

Answer 8

Yes

Answer 9

@cedric yeah, you were right earlier. Sorry for not replying for a bit.

Answer 10

oh okay thank you haha

Answer 11

so the only thing that that you didn't realise is that g=2b. has a consequence the equation should be b+g=112 and g=2b+16

Answer 12

ohhhhhh

Answer 13

But i still got the right answer in the end

Answer 14

I've made a mistake reading g=2b+16. got it look there "g is 16 more than twice the number of boys"

Answer 15

yes you may have got the right answer in the and but u always should look for really understanding the problem that's the key to understand and love math
