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)

$220.5 is the answer.
= 70(1+2.15)=70×3.15=220.5
Answer:
i think its y = 2.5x ?
Step-by-step explanation:
for every 5 units of black paint, there are 2 units of white paint,, this can be represented as
2y = 5x
divide everything by 2 to isolate y and you get
y = 2.5x
