Paranthesis and Exponents
(20 / 2^2 * 5 / 5) = 5
Multiplication
5*8= 40
Division
10 / 40 = 0.25
Subtraction
0.25 - 2 = −1.75
Therefore,
The answer is -1.75
The correct answer I would think would be C but I would try A because B does no have a proportion of 3/4.
Answer:
A(1,1)
Step-by-step explanation:
the system is :
2x-y=1
x+2y=3
so :
y = 2x-1 .....the line color : red
y= (-1/2)x+3/2......the line color : blue
the pair solution is the intersection point for this line : A(1 ; 1)
