3-|4-n|>1
Subtract 3 from both sides:
-|4-n| > -2
Multiply both sides by -1:
|4-n| < 2
Apply the absolute rule:
-2<4-n <2
4-n > -2
n < 6
4-n < 2
N >2
Combine the intervals:
2<n<6
(2,6)
Answer:
D
Step-by-step explanation:
Answer: a. 9:5
b: 14:9
Step-by-step explanation:
if there are 14 people in a class given 5 boys, then there are 9 girls. The values needed are boys (5), girls (9), and total students (14). Ratio Girls : Boys is 9 : 5 and Ratio All Students : Girls is 14 : 9
Question 2 is b.48
Question 3 is a.20 L
Step-by-step explanation:
We need to choose all the expressions that are equal to 61.
(i) |−61| : It is true. Modulus of any negative number gives positive number. |-61|=61.
(ii) The opposite of −61 ; It is true. Opposite of negative is positive.
(iii) The opposite of 61 : It is false. The opposite of 61 gives -61.
(iv) distance from zero to −61 : It is true. Distance is positive always.
(v) −|61| : False. It remains negative.
(vi) −|−61| : False. It remains negative.
(vii) -(-61) : True. Double negative makes positive
.
Hence, the correct options are : (i), (ii), (iv), (vii).
