1) Which ratio is expressed as a unit rate? A) 15 miles/5gal
B) $8.00/hr
C) 120min/3hr
D) $4.00/per package

D.

Step-by-step explanation:

Expressing something by a unit rate means to express a value per single item. Hence, only D fits (per package, meaning per 1 package.)

Hope this helped!

D

Step-by-step explanation:

per package, meaning per 1 package.

histogram or dot plot?

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
