What kind of question is this lol ? i don’t even understand it
B = g + 12
g + b = 124
Replace the b in the second equation with
g+ 12
g+ g+12=124
2g + 12 = 124
Subtract 12 from both sides
2g = 112
Divide by 2
g = 56
b= 56 + 12
b= 68
This problem is an example of an arithmetic series.
The common difference of the second term (15) with the first term (9) and the third term (21) with the second term (15) [15-9=6; 21-15=6] is 6.
The formula for solving this is:
An= A1 +(n-1)*d where An is the nth term, A1 is the first term, n is the number of terms and d is the common difference.
An=9+ (31-1)*6 = 189
The answer is 189.
The bigger box will have a volume 2^3 greater than the smaller box. That is 8 times larger.
So number of mugs it can hold is 8*8 = 64 mugs.
