Answer:
X= 5/12 + 1/24y
Y= -10 + 29x
Step-by-step explanation:
2(10- 24x)+ 2y 2(10- 24x)+ 2y
20 - 48x +2y 20 - 48x +2y
48x =20 +2y -2y = 20- 48x
/48 /48 /48 /-2 /-2 /-2
x= 5/12 + 1/24y y= -10 +29x
Ralph's height is y
Ben's height is x
Ben's height is 1/20 of Ralph's height. How tall is Ralph?
Answer: Choice D
b greater-than 3 and StartFraction 2 over 15 EndFraction
In other words,
b > 3 & 2/15
or

========================================================
Explanation:
Let's convert the mixed number 2 & 3/5 into an improper fraction.
We'll use the rule
a & b/c = (a*c + b)/c
In this case, a = 2, b = 3, c = 5
So,
a & b/c = (a*c + b)/c
2 & 3/5 = (2*5 + 3)/5
2 & 3/5 = (10 + 3)/5
2 & 3/5 = 13/5
The inequality
is the same as 
---------------------
Let's multiply both sides by 15 to clear out the fractions

---------------------
Now isolate the variable b

Side note: Another way to go from 47/15 to 3 & 2/15 is to notice how
47/15 = 3 remainder 2
The 3 is the whole part while 2 helps form the fractional part. The denominator stays at 15 the whole time.
