Answer:
Firstly, rewrite the equation:
⅓ (18 + 27) = 81
Substitute x for the given number of it's supposed equivalent.
In this case x = 12.
⅓ (18(12) + 27) = 81
Solve using PEMDAS and simplify what is in the parenthesis first. Then, multiply.
(18 x 12) + 27 = 243
Now, solving using PEMDAS, multiply the total of what you got that was originally in the parenthesis by ⅓ .
⅓ (243) = 81
When you multiple these number they are equivalent to 81.
81 = 81
Since the equation given, when substituted x for 12, is equivalent to 81, this proves that substituting x for 12 makes this equation true.
Yes he has enough inches of wire
Answer:C
Step-by-step explanation:
Daily team meeting is 20 minutes
=> total meeting time = 20 / 20% = 20/20 * 100 = 100 minutes
=> total working time = 100 / 20% = 100/20 * 100 = 500 minutes = 7 hours and 10 minutes
So if he starts at 7:30 am, he would be done at 14:40, which is 2:40 pm
Final result :
7b • (2a - 1) all over 6
