Answer:
The answer is 0.1x-16
Step-by-step explanation:
-3.4x+3x+.5x=0.1x and -25+9 is -16 which is 0.1x-16
Lets x = # pounds of coffe
70 - 8.06x = 37.76
- 8.06x = - 32.24
x = 4
Answer
4 lbs
The volume of titanium is 20.86 cubic inches
<em><u>Solution:</u></em>
The volume is given by formula:

From given,
Density of titanium = 4.51 
Mass = 3.4 lb
Let us convert the mass to grams
1 pound = 453.592 grams
Therefore, 3.4 pound is equal to:

Now substitute the values into formula:

Let us convert cubic centimeter to cubic inches
1 cubic centimeter = 0.0610237 cubic inches
Therefore,

Thus volume of titanium is 20.86 cubic inches
3 and 2/3 hours.
Multiply the number of hours Dominic spent by the scale factor.
