Question

Which expression has a value of 5?

(30+3)⋅5÷15−7open paren 30 plus 3 close paren times 5 divided by 15 minus 7,

30+3⋅5−(15+20)30 plus 3 times 5 minus open paren 15 plus 20 close paren,

30+(3⋅5−5)÷830 plus open paren 3 times 5 minus 5 close paren divided by 8,

30+3⋅5−(75÷5−10)

Answer 1

Explanation:

Option 1

`((30+3)5)/(15)-7=(33* 5)/(15)-7`

`=(165)/(15)-7`

`=11-7`

= 4

Option 2

`30+3* 5-(15+20)=30+3* 5-35`

= 30 + 15 - 35

= 45 - 35

= 10

Option 3

`30+((3* 5)-5)/(8)=30+(15-5)/(8)`

`=30+(10)/(8)`

`=30+(5)/(4)`

`=30+(4+1)/(4)`

`=30+(4)/(4)+(1)/(4)`

`=31+(1)/(4)`

`=30(1)/(4)`

Option 4

`30+3* 5-((75)/(5)-10)=30+15-(15-10)`

= 30 + 15 - 5

= 45 - 5

= 40

Therefore, None of the given expressions has a value of 5.
