What can you do when the unit prices for two comparable items are listed using different units of measures
a. the secondary units don't affect the cost. as long as both prices are in dollars or cents, you can
compare the two
b. the unit prices are based on the cost of the whole package, so divide each base cost by each unit
price to get comparable units.
c. use conversion rates to change one unit into the other unit, so that both prices are listed using like
units
d unit prices are ratios, so you can add the two prices together and divide by the smaller unit price to
get a usable number

the answer is d

step-by-step explanation:

so, converting firstly the mixed fractions to improper fractions and then "adding".

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
