Answer:
9.7 %
Step-by-step explanation:
Step 1
The formula for Percentage increase = increase/Original Amount × 100
Increase = Current amount - Original Amount
= 5 feet 8 inches - 5 feet 2 inches
= 6 inches
Increase = 6 inches
Step. 2
Before calculating Percentage increase, convert original amount to inches for easy calculation
Hence:
Original amount = 5 feet 2 inches
1 foot = 12 inches
5 feet = x
Cross Multiply
x = 5 × 12 inches = 60 inches
Original amount = 60 inches + 2 inches = 62 inches
Percentage increase
= 6 inches/62 inches × 100
= 9.6774193548%
Approximately = 9.7 %
The percent increase in her height = 9.7%

Since the second equation gives a value for a, we can substitute it into the other equation to find a value for B.
Let's substitute b-2 into the first equation wherever there is an a.
a - 3b = 4
(b-2) - 3b = 4
b - 2 - 3b = 4
-2 - 2b = 4
-2b = 6
b = -3
Now let's find a by substituting -3 into either of the equations to find the value of a.
a = b - 2
a = -3 - 2
a = -5
So your solution set is (-5, -3)
