Answer:
the answer is 0.
Step-by-step explanation:
1/3(21) - 1 - 1/2(12) = 7 - 1 - 6 = 0
12/3 = x/8
Cross multiply
3x = 96
Eliminate
3x/3 = 96/3
x = 32
Answer:
61,56
Step-by-step explanation:
1 = 3,24 so 3,24 x 19 = 61,56
Let X be large frames and Y be small frames.
X+Y=23
15X+5Y=195 or 3X+Y=39
Thus 2x=16
so X=8
so Y=15
