Question

Select all the statements for which y= 17/10.A.) 34/5 less than y is -51/10.B.) 21/10 more than y is 19/5C.) 18/5 less than y is -53/10D.) 15/2 more than y is 29/5.

Answer 1

A)

$-\frac{34}{5}+\frac{17}{10}=-\frac{68}{10}+\frac{17}{10}=-\frac{51}{10}$

So this is true

b)

$\frac{21}{10}+\frac{17}{10}=\frac{38}{10}=\frac{19}{5}$

So this is true

c)

$\frac{18}{5}-\frac{17}{10}=\frac{36}{10}-\frac{17}{10}=\frac{19}{10}$

So it is false

d)

$\frac{15}{2}+\frac{17}{10}=\frac{75}{10}+\frac{17}{10}=\frac{92}{10}=\frac{31}{5}$

So this is false
