You can put this solution on YOUR website! let a = C's age
;
Using the given formula
100 + = 127
subtract 100 from both sides = 27
multiply by 2
a = 54 yrs is C's age
You can put this solution on YOUR website! 100+(age/2)=systolic Subtract 100 from each side.
age/2=systolic-100 Multiply each side by 2.
age=2(systolic-100) For systolic=127
age=2(127-100)
age=2(27)
age=54 ANSWER: She is 54 years old.
