They are equal because no matter how many zeroes are the decimal point and all the numbers so 6.900000000000000 and 6.9 are equal.
It would take Adrian 4 days, if you add 3/4 four times all together you will end up with 12/4. Then you have to simplify it, getting the answer 3. Hope this helped! :)

Answer:
P = (18a+10b+13) cm
Step-by-step explanation:
Given that,
A triangle has the lengths of (10a+9) cm, (8a—3) cm and (10b+7) cm.
We need to find an expression that represents the perimeter of the triangle.
Perimeter = sum of all sides
P = (10a+9) + (8a-3) + (10b+7)
Taking like terms together,
P = (10a+8a)+10b+(9-3+7)
= 18a+10b+13
Hence, the epresssion for the perimeter is (18a+10b+13) cm.
Answer:
42
Step-by-step explanation:
Yes, you are right.
6 weeks * 7 days in a week.
so 7 days in all 6 weeks is 42 days.
