Well just plug those two numbers into the equation: 7(3) - 3(2) Which equals 15 so B) 15
Answer:
12
Step-by-step explanation:
You need to find the least common denominator (LCD) to all the denominators of the fractions present in the equation. These denominators are (writing them in their prime factor form to make our calculations easier):
Therefore, we need to include a factor of 3, and two factors of 2 (
) in our least common denominator, so this LCD will be a perfectly divided by all three given denominators, therefore eliminating all fractions in the equation.
Our LCD is = 
396 out of 2800 shirts are defected.
396/2800 * 100 = 14.1% of the shirts were defected
Answer:
1 : a set each of whose elements is an element of an inclusive set. 2 : division, portion a subset of our community.
Step-by-step explanation:
In mathematics, set A is a subset of a set B if all elements of A are also elements of B; B is then a superset of A. It is possible for A and B to be equal; if they are unequal, then A is a proper subset of B. The relationship of one set being a subset of another is called inclusion
