1) If P = 45 - [5 + (60 - (39 - 8)}] and Q = -12 + [25-2 {16 - 9}] then (p) + (Q) is equal to(i) 10(ii) - 10(iii) 12(iv) none of these.
Answers
Answer: (iv) none of these
Step-by-step explanation:
P = 45 - [5 + (60 - (39 - 8)}] and Q = -12 + [25-2 {16 - 9}]
= 45 - [5 + (60 - 31)] = -12 + [25 - 2(144)]
= 45 - (5 + 29) = -12 + (25 - 288)
= 45 - 34 = -12 + ( -263)
P =11 = -12 - 263
Q = -275
∴ P + Q = 11 + (-275)
= 11 - 275
P + Q = -264
Answer:
-10
Step-by-step explanation:
P = 45 - [5 + (60 - (39 - 8)}] and
= 45 - [5 + (60 - 31)]
= 45 - (5 + 29)
= 45 - 34
P =11
Q = -12 + [25-2 {16 - 9}]
= -12 + [25 - 2(7)]
= -12 + (25 - 14)
= -12 + ( 11 )
Q = -1
| P | + | Q |
as per additive inverse,
| 11 | + | -1 |
-11 + 1
-10
Hope it helps.
