First we divide 102 by 12.75 to get the hours which is 8 hours. So it would take 8 hours
Your answer is 9 is in the hundred thousands place because it is 9 hundred and sixty eight thousand and six hundred and foutry six.
Let x represent the number of pounds of $10.75/lb coffee used in the mix.
.. 10.75x +3.25(100 -x) = 5.65*100 . . . . . . total cost of coffee blend
.. x(10.75 -3.25) = 100*(5.65 -3.25) . . . . . .separate x-terms from non-x terms
.. x = 240/7.5 = 32
32 pounds of $10.75/lb coffee should be used
68 pounds of $3.25/lb coffee should be used
Answer:
True
Step-by-step explanation:
a x ( b + c ) = a x b + a x c Substitute
-5 x ( 11/8 + c ) = -5 x 11/8 + -5 x c
-5 ( c + 11/8) = - 5c - 55/8
- 5c - 55/8 = - 5c - 55/8
True
