A nature museum has 2008 specimens of early birds, some with 222 wings and some with 444 wings. The specimens have a total of 40
ludmilkaskok [199]

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,

x+y=2008

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

2x+4y=4384

we can divide both sides by 2

x+2y=2192

so, we get system of equations as

x+y=2008

x+2y=2192

we can solve for x and y

We can subtract both equations

2008-y+2y=2192

y=184

x=2008-184

x=1824

y=184,\:x=1824

so,

number of birds with 2 wings is 1824

number of birds with 4 wings is 184.............Answer

A and D

To get x on one side you have to, in this case, add 3 to both sides. This is the addition property of equality

Allen is trying to buy sneakers he has $50 to spend he finds a pair that he really likes that cost $58 if he has a 20% coupon ca
svetoff [14.1K]
First you would multiply 58 by .20 and you would receive 11.6
next you would subtract 11.y from 58 and get 46.4
so yes Allen can afford the sneakers

A superhero recently asked his nemesis how many cats she has. She answered with a​ riddle: ​"One-half of my cats plus two​."
mixer [17]
I got ten. Here's the equation. 

x = 1/2x + 5 

<span>Subtract 1/2x from both sides to get all x's on one side </span>

<span>x - 1/2x = 1/2x - 1/2x + 5 </span>

<span>1/2x = 5 </span>

<span>Now multiple the left by 2 to get x, but since it's an equation, you need to also multiply the right by 2 to keep it =. </span>

<span>2 * 1/2x = 2 * 5 </span>

<span>x = 10 cats</span>
