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

7

step-by-step explanation:

the answer would be 7

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
