We can calcualte the number of blue hats by multiplying the total number of hats (n=48) by the proportion of blue hats (p=25%=0.25).
Then:
There are 12 blue hats.
Answer: x = 4 + y
x= -2 - y/2
Step-by-step explanation:add y to both sides of the equation
Answer:
Step-by-step explanation:
Since you are doing 
squared, you have to multiply the exponents.
4 * 2 = 8
The resulting equation will be x + y = 4 and 4y =20
<h3>System of equation</h3>
GIven the system of equation given as:
x + y = 4
-3x + y = 8
If Megan multiplies the first equation by 3 then add the result to the second equation, the resulting equation will be:
3x + 3y = 12
-3x + y = 8
Adding both equation
3y + y = 12 + 8
4y = 20
Hence the resulting equation will be x + y = 4 and 4y =20
