Question

what is the value of the the expression x+5/y^2 for x = 2/3 and y= 1/3. A. 17/27 B. 17. C.34. D.51

Answer 1

Answer:

Step-by-step explanation:

x + 5/y^2

x = 2/3

y = 1/3

2/3 + 5 / (1/3)^2            Expand (1/3)^2

2/3 + 5 / (1/9)                Put a 1 underneath the 5

2/3 + 5/1 / (1/9)             Invert and multiply the second expression

2/3 + 5/1 * 9                 Simplify 5/1

2/3 + 5* 9                     Combine

45 2/3

I'm not getting any of these. It's possible I'm misreading the question, but what you've given is the result I got. All I can suggest is that you ask your teacher how this is done.
