The correct question is
<span>Mama Mia restaurant used start fraction, 1, divided by, 2, end fraction of their mozzarella cheese making pizza and the remaining 64 ounces making pasta.
How many pounds of mozzarella cheese did Mama Mia start with?
Let
x---------------> total </span>ounces of mozzarella
<span>
we know that
making pizza-----------> (1/2)*x------> x/2
therefore
making pasta-------> [x-x/2]--------> (2x-x)/2-----> x/2
making pizza=making pasta=x/2
(x/2)=64---------------> x=64*2-----------> x=128 ounces
remember that
1 ounces----------------> 0.0625 pounds
then
128 ounces*0.0625=8 pounds
the answer is 8 pounds

Answer:
x = 3
y = -2
Step-by-step explanation:
x + 2y = -1
2x – 3y =12
Using substitution means that in one equation you solve for a variable. In this case, the first equation would be easier to solve for x since there are no coefficients.
x = -2y - 1
Now, we plug in the value of x into the second equation, and solve for y.
2 (-2y - 1) - 3y = 12
-4y - 2 - 3y = 12
-7y - 2 = 12
-7y = 14
y = -2
Since we have a numerical value of y, we can use it to solve for x by plugging it into one of the original equations.
x + 2(-2) = -1
x - 4 = - 1
x = 3
If you'd like to check the answer, plug in both values you got to the original equations!
I hope this helps!
The x-intercept of an equation is the value of x when y is set to be equal to zero. On the other hand, the y-intercept is the value of y when x is set to be equal to zero. From the equation,
x-intercept : <span>3x - 9y = 10.8
3x - 9(0) = 10.8
x = 3.6
y-intercept: </span>3x - 9y = 10.8
3(0) - 9y = 10.8
y = -1.2
Answer:
a) 4x+5=y
1=5
2=13
3=17
4=21
5=25
b) no because at x=4 y equals 21 not 16.
