1.) The answer is 21
SOLUTION:
→ 15a - 9
15(2) - 9
→ 30 - 9
= 21
2.) The answer is -178
SOLUTION:
→ -18c + 2
-18(10) + 2
→ -180 + 2
= -178
3.) The answer is -40
SOLUTION:
→ x - 4y
(-4) - 4(9)
→ -4 - 36
= -40
4.) The answer is 40
SOLUTION:
→ abc - ab
(2)(4)(6) - (2)(4)
→ 48 - 8
= 40
5.) The answer is -11
SOLUTION:
→ 12/x+y - x+y
12/4+8 - (4+8)
→ 12/12 - 12
1 - 12
= -11
