Why/How to Get Answer: Both the typing time and the printing time are per page.
This means that the typing plus printing time is:
30 x 13 + 3 x 13 = (30 + 3) x 13 or 429 minutes.
Converting to hours:
Total Time = 429 minutes x 
=
If you divide 40 by 8
40 ÷ 8 = 5
Multiply 5 by 7
5 × 7 = 35
35 is 7/8 of 40.
To get from 12 smores to 3 smores, you divide by 4. Therefore, you divide the amount of ingredients by 4 also, which is 12 ÷ 4 = 3 and 8 ÷ 4 = 2. So she needs 3 marshmallows and 2 Graham crackers for 3 smores. Hope this helped!
The answer is
c - 5 : 1
5m = 500 cm
Let the weight of the full Volume of nails in the box be W.
Let the weight of the box be B.
2/3 W + B = 130 ........i From the first statement.
3/8 W + B = 74 ......ii From the second statement.
Equation (i) Minus (ii)
2/3 W - 3/8 W + B - B = 130 - 74
(16W - 9W) / 24 = 56
7W / 24 = 56.
W = 56 * 24 / 7
W = 192 Pounds.
Substituting V = 64 in equation (i)
2/3 W + B = 130
2/3 * 192 + B = 130
2 * 64 + B = 130
128 + B = 130
B = 130 -128 = 2.
Therefore, weight of box, B = 2 pounds.
