if 5 is subtracted form 4 times of a number gives 19 then number is ??
Answers
Answer:
Question 1:
Evaluate:
(i) 15 + (−8)
(ii) (−16) + 9
(iii) (−7) + (−23)
(iv) (−32) + 47
(v) 53 + (−26)
(vi) (−48) + (−36)
ANSWER:
(i) 15 + (−8) = 7
(ii) (−16) + 9 = −7
(iii) (−7) + (−23) = −30
(iv) (−32) + 47 = 15
(v) 53 + (−26) = 27
(vi) (−48) + (−36) = −84

Question 2:
Find the sum of:
(i) 153 and − 302
(ii) 1005 and − 277
(iii) − 2035 and 297
(iv) − 489 and − 324
(v) − 1000 and 438
(vi) − 238 and 500
ANSWER:
(i) 153 + (−302) = −149
(ii) 1005 + (−277) = 728
(iii) (−2035) + 297 = −1738
(iv) (−489) + (−324) = −813
(v) (−1000) + 438 = −562
(vi) (−238) + 500 = 262

Question 3:
Find the additive inverse of:
(i) − 83
(ii) 256
(iii) 0
(iv) − 2001
ANSWER:
(i) Additive inverse of −83 = −(−83) = 83
(ii) Additive inverse of 256 = −(256) = −256
(iii) Additive inverse of 0 = −(0) = 0
(iv) Additive inverse of 2001 = −(−2001) = 2001

Question 4:
Subtract:
(i) 28 from − 42
(ii) − 36 from 42
(iii) − 37 from − 53
(iv) − 66 from − 34
(v) 318 from 0
(vi) − 153 from − 240
(vii) − 64 from 0
(viii) − 56 from 144
ANSWER:
(i) −42 − 28 = (−42) + (−28) = −70
(ii) 42 −(−36) = 42 + 36 = 78
(iii) -53 - (-37) = (-53) - (-37) = -16
(iv) -34 - (-66) = -34 + 66 = 32
(v) 0 - 318 = -318
(vi) (-240) - (-153) = -87
(vii) 0 - (-64) = 0 + 64 = 64
(viii) 144 - (-56) = 144 +
