Since he completes 10 minutes each day for five days, he completes 50 minutes.
The percentage of his total requirement would be 50/100 = 0.5 = 50%.
When the bases are diffenrent and the exponents of a and b are the same, we can multiply a and b first:
a n ⋅ b n = (a ⋅ b) n
Example:
32 ⋅ 42 = (3⋅4)2 = 122 = 12⋅12 = 144
When the bases and the exponents are different we have to calculate each exponent and then multiply:
a n ⋅ b m
Example:
32 ⋅ 43 = 9 ⋅ 64 = 576
Since the 1/4 of each pizza left :
Which means that :
Pizza 1 = 1/4 pizza Left
Pizza 2 = 1/4 pizza Left
i think there is no error in what's ben saying
3w-7w-12=2w-6
-4w-12=2w-6
-12=6w-6
-6=6w
w=-1
If that's an addition sign, then b=-35.
If it's a division sign, then b=-150
Sorry I can't see which it is! Hope this helped though :)
Good luck!
