Answer:
1. x-15
2. [tex]\frac{12}{t}[/tex]
3. 4y
4. z+7
5. eight groups of p
6. the sum of s+7
7. 8(8)+3 = 67
8. 3(7+4)= 33
9. (4)-5(-1)+[tex](4)^{2}[/tex]=> 4+5+16 = 25
10. (-7)-[tex](3)^{2}[/tex] = -7 -9= -16
11. [tex]\frac{1}{2}[/tex](8)(4+6) => [tex]\frac{1}{2}[/tex](8)(10) = 40
12. No, 7+7x ≠ 7x +1
13. Yes, 2.5(3+x) = 2.5x + 7.5 => 7.5+ 2.5x = 2.5x + 7.5
14. [tex]m^{2}[/tex]-2m-5
15. 13x-24
16. [tex]3b^{2}[/tex]
17. 14p+7
