Question

Mrs. Brown has 7 more boys than girls in her class and has a total of 29 students. Which of the following systems of equations could be used to solve this problem?
B = G – 7 and B + G = 29
G = B + 7 and B + G = 29
B + 7 = G and B + G = 29
B = G + 7 and B + G = 29

Answer 1

Answer:

B = G + 7 and B + G = 29

Step-by-step explanation:

Let B = boys and G = girls. There are 7 more boys then girls. Set the equation:

B = G + 7

There are 29 students in total. Set the boys and girls equal to the total amount:

B + G = 29

B = G + 7 and B + G = 29 is your answer.
