Answer:
1 day and 8 hours
Step-by-step explanation:
Adan does 1/3 work each day,
Bernie does 1/4 work each day, and
Cynthia does 1/6 work each day
combined they accomplish 3/4 each day
therefore it would take them 1 day and 8 hours
Combine like terms (terms with the same variable (letter)). Remember to bring the sign.
4c - 4d + 8c - 3d
4c + 8c = 12c
-4d - 3d = -7d
12c - 7d is your answer
hope this helps
I think u have to multiply 4 times .07 then that get you .28 cents
To make ∠ADC is a right angle, value of x will be 7.
From given figure, it is observed that Angle ADC is combination of two angles ADB and BDC.
∠ADC=∠ADB+∠BDC
Since, ∠ADC is right angle.
So, ∠ADC=90 degree
90=∠ADB+∠BDC
