The property used is B: addition property
Step-by-step explanation:
The addition property of equality states that if you add the same number to both sides of an equation, the equation balances.In this case;
5x-9<91------------performing addition property of equality

A = k/R where A = acceleration and R = radius of the turn and k is a constant to be found.
Substituting the given values:-
10 = k / 70
k = 10*70 = 700
So the equation of the motion is A = 700 / R
When the radius is 140 the acceleration is 700 / 140 = 5 ft/sec/sec ( answer)
