Answer:
There is NO solution
Step-by-step explanation:
Considering 'y' be the number
Considering x be the smaller number
As 'y' is equal to twice a smaller number plus 3.
so
also
y is equal to twice the sum of the smaller number and 1.
so
so the system of equations become
solving
Therefore, there is NO solution.
230 because i think 20% is 200 and 23% is 230. hope this is right, if its wrong i,m sorry.
We know that
the area A of the circular cross section of the pipe is
A=pi*r²
D=20 cm------------- > r=D/2=20/2=10 cm
then
A=pi*10²=100*pi cm²
the answer is A=100*pi cm²
Answer:
2+i or 2-i (D)
Step-by-step explanation:
First you use the quadratic formula. X= (-b +/- 
)/2a
a=1
b=-4
c=5
X= (4 +/- 
)/2
X=(4 +/- 
)/2
The square root of -4 is 2i. i=√-1. Therefore 2i= 2√-1 .If you simplify that, it becomes √-4i.
X= (4+/- 2i)/2
X= 2+/-i
X= 2+i or 2-i
