Answer: (1/3,2)
Step-by-step explanation:
Let O(x,y) be the circumference of the triangle PQR,
Thus, by the property of circumcenter all the vertices of the triangle are at same distance from this circumcenter.
Thus, PO = QO
By the distance formula,
---------(1)
Similarly, QO = RO
------------(2)
By adding equation (1) and (2),
24 x = - 8
x = 1/3
By putting this value in equation (1),
We get,
Thus, 4 - 8 y = -12
8 y = 16
y = 2
Answer:
y=-5x+19
Step-by-step explanation:
yeah -ya...... right?
Square root 144 = 12 so this is the rational number
Answer: 0.06x
Step-by-step explanation:
- An algebraic expression is an expression consist of integer constants, variables, and algebraic operations.
The given statement: A number is 30% of 20% of the number x.
The required algebraic expression would be:
30% of 20% of x
[we divide a percentage by 100 to convert it into decimal]
Hence, the required algebraic expression would be :
0.06x
Let us take a number x
The four consecutive numbers will be
x+1, x+2, x+3
Thus our equation will be
x + x+1 + x+2 + x+3 = 42
4x + 6 = 42
4x = 36
x= 36/4
x= 9
Thus the four numbers are (substitute)
x=9
x+1=9+1=10
x+2=9+2=11
x+3=9+3=12
9,10,11,12
