Apack of cardinal flower seeds costs $4, and a pack of petunia flower seeds costs $2.50. you buy the same number of packs of each type of flower and spend $39. how many packs of each do you buy?

6 packs of each flower type

Step-by-step explanation:

4 * 6= 24

2.50*6=15

24 + 15 = 39

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
