It can't be simplified since 29 is a prime number EDIT: it cant be simplified into whole numbers lol
Answer: 25
Step-by-step explanation: -5 x 25 + 13 = -112
2x + 4y + 2 = 3y + 5
2x + 4y - 3y + 2 - 5 = 0
2x + y - 3 = 0
Not sure however I keep getting 1
In the 7th and 8th grade combined, there 3+5 girls = 8 girls, and 7+5 boys = 12 boys. If there are only boys and girls, then there are 12+8=20 students in all.
The fraction of girls out of the total is P = 8/20 = 2/5.
