Answer: 1. a 2. 6+5x 3. d 4. a 5. a) 4(8+x)=52 b) 5 girls c) Each student has 4 pencils. Since the number of pencils they have all together is 52, I divided 52 by 4 and got 13. 13 minus 8 (the number of boys) equals 5 (the number of girls.) To set the equation up, I set it equal to the number of pencils, and put the number of students broken down into boys and girls (8+x, x being 5) and multiplied it by 4, the number of pencils. 6. z+12
Step-by-step explanation: Sorry for the long explination on C of 5. I tried to shorten it up as much as possible. I am taking a college math class as a sophomore in highschool, as I tested out of all the normal classes, so I hope I didn't miss anything lol. I hope this helps :)
