Answer:
[4*(4+3)]-3 = 25
[(7-5)-: 1/2]*2 = 8
((5.4+3)*(6-2)) = 33.6
(9)/(3)+6)*3 = 27
(4+3.2)*[(9-2)+2.5] = 68.4
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
To check if (2,3) is a solution to the system of equations, we simply have to plug the coordinate points into the two equations and see if it is valid.

(2,3) belongs in the first equation.

(2,3) does not belong in the second equation.
<u>Therefore, (2,3) is not a solution to this system of equations.</u>

The ratio of circumference to diameter is independent of the radius.
Defining C=circumference, r=radius, D=diameter = 2r
Circumference = C = 2 π r = π D
=>
ratio of circumference / diameter
= C/D = π
