The first one is the right answer
Answer:
After 5.6 weeks they will have the same number of comic books.
Number of books = 61
Step-by-step explanation:
Tom currently has 5 comic books in his collection and has subscribed to receive 5 new comic books each month.
Again, his uncle has 145 comic books but sends five to each of his 3 nieces each month.
As Tom is one of his nieces so, in every week the collection of tom gets increases by (5 + 5) = 10
Therefore, after w weeks tom's collection will have C₁ = 5 + 10w ......... (1)
And Tom's uncle will have after w weeks C₂ = 145 - 15w ............ (2) comic books in his collection.
If C₁ = C₂ , then
5 + 10w = 145 - 15w
⇒ 25w = 140
⇒ w = 5.6 weeks.
Therefore, after 5.6 weeks they will have the same number of comic books. (Answer)
And the number of books it will be
C = 5 + 10 × 5.6 = 61. (Answer)
Explanation
The sum of the three angles of a triangle has to be equal to 180 degrees.
So...
180-(75+50)
180-125
=55 degrees
X equals 55 degrees
Step-by-step explanation:
3(4 *to the power of 2* - 3*to the power of 2*)
24-23 x 3
3*to the power of 3* - 3*to the power of 2
(6*to the power of 2* - 3) (9*to the power of 2* - 70)
- (6²-3)(9²-70)
- (36-3)(81-70)
- (33)(11)
- 363
Hence, Option d. is the correct answer because it gives answer 3 when it is solved.
