So 20 plus g if it makes 25 then we already know that g is 5 because 20 plus 5 makes 25
Answer:
66 HR
Step-by-step explanation:
We can set up an equivalent proportion and cross-multiply like this:
22/7=x/21
Cross multiply.
7x=462
Divide by 7 on both sides.
x=66

Answer: 10
Explanation:
n(A × B) represents the number of elements of set A × B, the cartesian product of set A and set B.
Note that the number of elements of the cartesian product of two sets is the product of the number of elements of each of the two sets.
In the problem, n(A × B) is equal to the product of the number of elements of set A and number of elements of set B. Since the number of elements in set A is 5 and the number of elements in set B is 2,
n(A × B) = 5 × 2 = 10
The greatest common factor of 18 and 54 is 18
One way to determine the greatest common factor is to find all the
factors of the numbers and compare them.
The factors of 18 are 1, 2, 3, 6, 9, and 18.
The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54.
The common factors are 1, 2, 3, 6, 9, and 18. Therefore, the
greatest common factor is 18.
The greatest common factor can also be a calculated by identifying
the common prime factors and multiplying them together.
The prime factors of 18 are 2, 3, and 3.
The prime factors of 54 are 2, 3, 3, and 3.
The prime factors in common are 2, 3, and 3, so the greatest common
factor is 2 x 3 x 3 = 18.
hope this help
