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)

`-(34)/(5)+(17)/(10)=-(68)/(10)+(17)/(10)=-(51)/(10)`

So this is true

b)

`(21)/(10)+(17)/(10)=(38)/(10)=(19)/(5)`

So this is true

c)

`(18)/(5)-(17)/(10)=(36)/(10)-(17)/(10)=(19)/(10)`

So it is false

d)

`(15)/(2)+(17)/(10)=(75)/(10)+(17)/(10)=(92)/(10)=(31)/(5)`

So this is false
