Answer:
The set notation for the diagram is P-Q
Answer:
D) 2275
Step-by-step explanation:
Answer:
The number is 24
Step-by-step explanation:
Let the two digits number be ab
In real terms, this is 10a + b
So, we have that the sum of the digits subtracted from 10a + b is 18
Mathematically, we have this as;
10a + b - (a + b) = 18
10a + b - a - b = 18
9a = 18
a = 18/9
a = 2
We are also told that the digit at the units place b is double the digit at the ten’s place a
That means b = 2a
b = 2 * 2 = 4
X=2, and line AB is 15, line BC is 15, and line CA, is 19
Answer:
10*(2)^(n-1)
Step-by-step explanation:
The common ratio of the sequence is 20/10=40/20=2.
The first term is 10 so the equation is 10*(2)^(n-1)
