if c/d – a/b =x, a =2c, and b=5d, what is the value of c/d in terms of x?
D) 5/3 X
Answer:
d) 5/3 x
Step-by-step explanation:
You substitute a for 2c and b for 5d, so your equation will look like this:
c/d – 2c/5d = x
Then you just simplify into x by making c/d into 5c/5d so you have a common denominator.
5c/5d – 2c/5d = x
3c/5d = x
5/3 is your answer
