Answer:
r= 1/2
Step-by-step explanation:
Subtract 7 from both sides of the equation
2 + 7 = 1 6
2 + 7 − 7 = 1 6 − 7
Simplify
2 = 1 6 − 7
Subtract 16r from both sides of the equation
2 − 1 6 = 1 6 − 7 − 1 6
-14r= -7
Divide both sides of the equation by the same term
− 1 4 = − 7
-14r=-7
− 1 4 − 1 4
=> 2r + 7 = 16
=> 2r = 16 - 7
=> r = 9/2
=> r = 4.5
5/4 hope this helps
i will try to solve the probability
