30 questions worth 2 points, and 10 questions worth 4 points.
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:
Step 1 of 5
(1). Familiarize.
<em>The energy in the slice of carrot cake is described in terms of the requirement of energy of an adult on a day.
</em>
<em>
</em>
<em>So we let x calories = the requirement of energy of an adult on a day.</em>
<em>3/4 ( x ) calories
</em>
<em>
</em>
<em>Then is the energy in the slice of carrot cake.
</em>
<em>
</em>
<em>The energy in the slice of carrot cake is 1560 calories.</em>

The y intercept is 3 because that is where the point aligns to the axis
