Your varible is A depends what the teacher ask if not just A it will be 8a
Answer:
<em>1 : 2</em>
Step-by-step explanation:
<u>First situation</u>
sides of triangle:-
a=x, b=2x, c=3x
then perimeter = a+b+c
perimeter = x + 2x + 3x
<em>Perimeter = 6x</em>
<u>Second situation(sides are doubled)</u>
sides of triangle:-
a=2x, b=4x, c=6x
then perimeter = a+b+c
perimeter = 2x + 4x + 6x
<em>Perimeter = 12x</em>
<u>Ratio of first situation to second </u>
Perimeter of first situation : Perimeter of second situation
6x : 12x
<em>1 : 2</em>
Answer:
(1,2)
or
x = 1
y = 2
Step-by-step explanation:
To solve the system of two linear equations by graphing, plot the graphs of both lines (linear equation represents the line).
1. The line with the equation intersects the y-axis at point (0,7) and the x-axis at point . Connect these to points with the straight line.
2. The line with the equation intersects the y-axis at point (0,4) and the x-axis at point . Connect these to points with the straight line.
he point of intersection (1,2) of these two lines is the solution to the system of two linear equations.
