10. 23
11. -17
12. 0
13. -4
14. -6
15. 4
Explanation:
10. 8+15= 23
11. -8-9= -17
12. 8-8= 0
13. -8+4= -4 (same as 4-8)
14. -10+4= -6 (same as 4-10)
15. 12-8= 4
s=x/3+10/3
x =
using the ' laws of exponents '
• × =
• ÷ =
• ()^n =
× = ÷ =
=
equating the exponents since bases on both sides are 7
4x = 5 - 3x
7x = 5 ⇒ x =
