Answer:
the measure of AB =29 meters

Thats what you would use, so now 2/10 is .2 When you divide so you move the decimal so 20%
The percent increase is 20%
Let
R = Ralph's age
S = Sara's age
First statement is translated as:
S = 3R
Second statement is translated as:
S + 4 = 2(R + 4)
Use the first equation to be substituted into the second one in terms of R which is the one we are actually going to solve for Ralph's age.
Since S = 3R, then
3R + 4 = 2(R + 4)
3R + 4 = 2R + 8
3R - 2R = 8 - 4
R = 4 years old
-4.5 might be the answer im not very sure but yeah
Answer:
none of these
