Some birds were flying and met a bird on their way. The bird greeted them; hello hundred! They said we are not hundred, we need half of us plus you to make us hundred. Question: How many birds were flying? Possible answers A. 198 B. 49 C. 66 D. 51 E. 101 F. 199 . Please help me with the answer. 49

There were 199 birds flying ⇒ F

Step-by-step explanation:

Assume that the number of birds is x

∵ They said "we need half of us plus you to make us hundred"

- That means one-half x plus 1 equals hundred

∴ x + 1 = 100

- Subtract 1 from both sides

∴ x = 99

- Multiply both sides by 2

∴ x = 198

∵ The number of bird were flying is x + 1

∴ The number of bird were flying is 198 + 1 = 199

There were 199 birds flying

To check the answer they said we need half of them plus you to bee hundred

one-half 198 is 99 + 1 = 100, so the answer that x = 198 is correct

The number of birds were flying are 198 + the bird they met in their way, so there were 199 birds flying

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7

step-by-step explanation:

because i took test

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
