step 1
Convert pint to cups
Divide 4/5 pint by 1/2 to convert to cups
so
step 2
Convert to mixed number
therefore
Joy is correct
Answer:
8x^2 - 10x = 0
Step-by-step explanation:
Standard format of a quadratic equation :
ax^2 + bx + c = 0
Y + 4 + 3(y+2)
y + 4 + 3y + 3*2
4y + 4 + 6
4y + 10
z^2 + z+ 4z^3 + 4z^2
5z^2 + z + 4z^3
1/4 (16 + 4p)
16/4 + 4p/4
4 + p
First let's start with the relationship between grams and centigrams and grams and milligrams.
1 gram = 100 centigrams
1 gram = 1000 milligrams
Because these two equations are equal, we can rewrite our equation as 100 centigrams = 1000 milligrams.
Now we divide by 100 to simplify our equation to 1 centigram = 10 milligrams.
With this simplified equation we see that we multiply the number of centigrams by 10 to find the equal number of milligrams.
So, I would set this up as a system of equations problem. x=y+8 and x=3y Then, you can substitute one equation for x. y+8=3y Next, you’ll want to solve for y.
