What should be added to the product of 2 , 4 by 7 (a mixed fraction ) to 3 to get 21, 5 by 14 (a mixed fraction). Pls give me a answer

Answer»

rong>Answer:

18 ¹¹/14

Step-by-step EXPLANATION:

Here you should not have mention 3. Because it is is BECOMING a mistake in the question. so excluding the 3, I am solving the problem.

Let us TAKE the number that should be added as x

Now, 2 ⁴/7 = ¹⁸/7

i.e

  • ¹⁸/7 + x = 21 ⁵/14
  • ¹⁸/7 + x = ²⁹⁹/14
  • x = ²⁹⁹/14 - ¹⁸/7
  • x = ²⁶³/14
  • x = 18 ¹¹/14

Ans :- The number that should be added is 18 ¹¹/14.

In the following figure, find the value of ∠BOC, if points A, O and B are collinear.

Answer» ONG>ANSWER:

⟹∠AOD+∠DOC+∠BOC=180∘

⟹(x−10)∘+(4x−25)∘+(x+5)∘=180∘

⟹(6x−30)∘=180∘

⟹6x−30=180

⟹6x=210

⟹x=6210

⟹x=35

∠BOC=(x+5)∘=(35+5)∘=40∘
