Okay so
If there are 28 white ducks, and twice as many brown ducks thats
28x2=56
So the total amount of ducks is 56(brown)+28(white)=84
Then, if half the amount of while ducks fly away thats
84-14=70 (You get 14 by diving the amount of white ducks by 2 28/2=14)
Therefore, there are 70 ducks in the pond after half the amount of white duckies fly away.
Answer:
x ≈ 3.4 cm
Step-by-step explanation:
Using the sine ratio in the right triangle
sin57° = 
= 
( multiply both sides by 4 )
4 × sin57° = x , thus
x ≈ 3.4 cm ( to 1 dec. place )
Answer:
Pretty sure the answer would be x=6
Step-by-step explanation:
The number (x) in: "3 more than twice a number is 15" is what we are solving here.
In other words, you are looking for a number (x) that if you multiply it by two (same as twice) and then add 3, you get 15.
To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 15
Then you solve the equation by subtracting 3 from both sides, and then divide both sides by 2. Here is the math to illustrate better:
2x + 3 = 15
2x + 3 - 3 = 15 - 3
2x = 12
2x/2 = 12/2
x = 6
