For this case we must find the unit cost of the dresses Sara bought taking into account that I spend a total of $ 80.34. To do this, we must divide the total cost by 3.
Let the variable "x" be the unit cost for each dress.
Thus, each dress cost Sara 26.78 $
Answer:
Each dress cost Sara 26.78 $
80.34 / 3 = 26.78
Combine like terms.
6x + 5z + 4
m = 35°
Step-by-step explanation:
Supplementary angles, sum = 180°
m + 145° = 180°
m = 180° -145°
