2: With P being the photographs, the equation is P= $242.73/ 27 copies
5: I’m just guessing that it’s asking for you to say it aloud so “a number minus 13 equals 15”
6: Same for 6, 8 times a number (or you can replace “a number” with its respective letter) plus 1
7: To set up the equations, we can call the pencils “x” and the stacks of paper “y”. The equation would be 5x+y=18. Since the paper is worth $9, we can substitute the y value for 9, giving us 5x+9=18. Simplifying this through subtracting 9 from both sides gives us 5x=9. And finally, you divide by 5 on both sides to give us the absolutely disgusting rational number of $1.80 a box (9/5=1 4/5= 1.8).
If you need any more help, just ask the ninth grader! Unless you’re past geometry or it’s about social studies that is
