Answer:

90 minutes

Step-by-step explanation:

let x=amount of time it would take for Shelby to knit the scarf

\frac{15}{5} =\frac{x}{30}

cross multiply

15*30=5x

450=5x

450/5=x

x=90

It would take Shelby 90 minutes to knit a scarf that is 30 inches long.

Which expression is equivalent to 8?<br><br><br> -48 ÷ 6<br> 48 ÷ (-6)<br> 48 ÷ 6<br> -48 ÷ (-6)
V125BC [204]
Expression 3, 
because 6 and 8 are factors of 48. Since positive 6 & 8 are the two numbers of choice, the product will be positive. My answer is reasonable because if you were to multiply positive 8 and 6 you will get positive 48.
