Let x = pounds of $12 per pound coffee
then
20-x = pounds of $9 per pound coffee
.
12x + 9(20-x) = 10(20)
12x + 180 - 9x = 200
3x + 180 = 200
3x = 20
x = 20/3
x = 6 and 2/3 pounds of $12 per pound coffee
.
Amount of $9 per pound coffee:
20-x = 20-20/3 = 60/3 - 20/3 = 40/3
or
13 and 1/3 pounds of $9 per pound coffee

Answer:
x = 5/2 & x = 1/3
Step-by-step explanation:
Create two equations and solve
1) 2x-5 = 0 & 2) 3x-1 = 0
1) 2x = 5
x = 5/2
2) 3x = 1
x = 1/3
You create two equations as you want the left hand side (LHS) to equal 0 (RHS), thus if one of the brackets becomes 0 it will result in the whole LHS beocming 0 as the brackets are being multiplied (anything multiplied by 0 = 0)
Hey there.
If the decimal point is .500 and up, we will be rounding up. If it is .499 and lower, we will be rounding down.
Now let’s look at the numbers.
2.500 g can be rounded up, so we’ll make that 3.000 g.
5.000 g is going to stay the same, since the decimal point is .000
2.268 g will be rounded down, making it 2.000 g
5.670 will be rounded up and will become 6.000 g
And finally, 11.340 g will be rounded down to 11.000 g.
Hope this helps!
