Amy bought 5 books for $0.50 and 7 for $.30, a total of 12
WORK
5 x .50 = 2.5
4.95 - 2.5 = 2.45
2.45 divided by .35 = 7

Step-by-step explanation:
Answer:
111
Step-by-step explanation:
if angle 8 and angle 4 are equal, then angle 8 and angle 5 are equal
so... angle 5= angle 4
Answer: x = 57
Step-by-step explanation:
Since CD = AC, triangle ACD is isosceles, therefore
ADC = DAC
ADC + DAC + 112 = 180
ADC + DAC = 180 -112 = 68
ADC + DAC = 68/2 = 34
DEB = 180 - 34 - 23 = 123 (sum of interior angles of a triangle = 180)
Therefore, x = 180 - 123 = 57 (DEB and x are supplementary angles)
