Answer:
They repesent how to divied
Step-by-step explanation:
Let's assume
number of birds with 2 wings is x
number of birds with 4 wings is y
A nature museum has 2008 specimens of early birds
so,

Total of wings of 2 wings bird =2x
Total of wings of 4 wings bird =4y
The specimens have a total of 4384 wings
so, we get

we can divide both sides by 2

so, we get system of equations as


we can solve for x and y
We can subtract both equations





so,
number of birds with 2 wings is 1824
number of birds with 4 wings is 184.............Answer
Answer:
Width of the pool = 15 yards
Step-by-step explanation:
Given that:
Length of diagonal of swimming pool = 29 yards
Length of the pool = 25 yards
Let,
w be the width.
This will form a right angled triangle where the diagonal will be hypotenuse.
Using Pythagorean theorem;

Taking square root on both sides

Rounding off to nearest whole number
w = 15 yards
Hence,
Width of the pool = 15 yards
Answer:
9 6/8, 9 3/4. 9.75
Step-by-step explanation:
1 1/4 would equal 10/8 if she has 10 7/8 then you'd take 7/8 out of 10/8 which would leave you with 2/8 left which you'd take out of the whole number 10 which would leave you with 9 6/8
simplified answer is 9 3/4
or: 9.75
6(3x + 4) + 5(12-x) simplifies to
D) 13x + 84
