Answer:
Step-by-step explanation:
U is the universal set, that is, a set that contains the universe of possible sets, which is formed by 10 elements in this. Q is a subset of U formed by three elements: 3, 6, 9. (
)
represents the complement of the complement of 
. The complement of is the subset of 
formed by elements not contained in . which simbolized by 
. That is, 1, 2, 4, 5, 7, 8, 10.
The complement of corresponds to the elements contained in . Hence, the correct answer is .
Answer:
y-10=9(x+8) in standard form is 9x −y =−82
Answer:
5 of the 7 boxes are 8 inches in height
Step-by-step explanation:
Mathematically;
1 ft = 12 inches
So, 5 ft will measure 5 * 12 = 60 inches
So from what we have ,
We want to combine 8 and 10 inches to give 60 inches total
Let the number of 10 inches be x and the number of 8 inches be y
Mathematically;
x + y = 7 •••••(i)
10x + 8y = 60 ••••(ii)
From equation i, x = 7-y
Put this in equation ii
10(7-y) + 8y = 60
70-10y + 8y = 60
70-60 = 10y-8y
2y = 10
y = 10/2
y = 5
Answer:
10 feet
Step-by-step explanation:
you would just have to do 5*2 which equals 10
