You find a common denominator, for example, if you want to subtract 3/4 minus 1/2 you would have to multiply 1/2 by 2/2, which equals 2/4, then you can do 3/4-2/4, which is 1/4. Sorry if it’s a bit confusing, hope it helps!
Yeah, x= 7/2 and y= -5/2

Answer:
<em>The fraction of the flour Mrs. Mannng will use for her chocolate chip cookies is 4/9</em>
Step-by-step explanation:
<u>Fraction of Portion</u>
Suppose we have a number n and another number m such as m>n. The portion or fraction of size n of m is given by the quotient n/m.
For example, 3 pieces of cake out of a total of 6 make them a fraction of 3/6 = 1/2 of the whole cake, i.e. half of the total available.
Mrs. Manning needs 1/3 cup of flour to make cookies for the bake sale. She actually has 3/4 cups of flour. Calculate the fraction of needed against the available flour:

The division can be easier performed by multiplying by the reciprocal of the denominator:


The fraction of the flour Mrs. Mannng will use for her chocolate chip cookies is 4/9
In order to answer this one, it's really really really really helpful if you know what the law of cosines says. In fact it's absolutely necessary.
The law of cosines says if you know two sides of a triangle and the angle between them then you can use that information to find the length of the third side.
In the picture you know the lengths of two sides and you know the angle between them. So you can use the law of cosines to find the length of the third sidethat. That's side AC.
