Answer:
The one on the bottom right
Step-by-step explanation:
So, since there are two equations, we can substitute one of them into the other. In this case, it would be easiest to substitute 2b=6a-14 into the other equations. But first, simplify by dividing both sides by 2. You bet b=3a-1
We can now plug this into the other equation
Sine the equation b=3a-1 results in the value of b, we have to plug in for the value of b in the other equation
So this is what we get after plugging in:
3a-(3a-1)=7
Now, simplify. 3a-3a+1=7
Since 3a-3a = 0, this equation results in a no solution
Answer:
The result is a no-solution, or Ф
Hope this helped!! :D
Answer:
n<-1
Step-by-step explanation:
Distribute 5 and -5 into each parenthesis respectively: 40n+35<5-5n-15
Combine like terms: 40n+35<-5n-10
Add 5n to both sides: 45n+35<-10
Subtract 35 from both sides: 45n<-45
Divide both sides by 45: n<-1
Answer: Radius = 10 cm and Arc length = 5 cm
Step-by-step explanation:
The area of a sector with radius r and central angle 
(In radian) is given by :-
Given : A sector of a circle has area 
and central angle 0.5 radians.
Let r be the radius , then we have
Thus, radius = 10 cm
The length of arc is given by :-
Hence, the length of the arc = 5 cm
Answer:
4.9 m²
Step-by-step explanation:
Area of a Triangle = (base * height)/2
(3.5*1.4)/2 = 2.45 m² = A of CBD
(3.5*1.4)/2 = 2.45 m² = A of BCA
