Answer:
x = 2
y = 1
Step-by-step explanation:
2x - 3y = 1
y = x - 1
2x - 3( x - 1 ) = 1
y = x - 1
2x - 3x + 3 = 1
y = x - 1
-x + 3 = 1
y = x - 1
-x = -2
y = x - 1
x = 2
y = 1
Yes 0 is a positive number ! :)
Set up a proportion and then cross multiply to solve. OR. 15/5 = $3 per bag is the unit rate per 1 bag.
Multiply 27*3=$81
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:
