Answer:
3 1/8
Step-by-step explanation:
25/9 * 9/8 =
9's cancel out
25/8 =
3 1/8
The answer is
2/5 = 0.4
Because
2/5 2 divide 5 = 0.4
The ratio House blend/Organic Free Trade blend is the same and must remain the same.
So, the proportion is:

Where x is the unknown amount of the Organic Free Trade blend.
So, from the proportion, we have:

Answer: 156 pounds of Organic Free Trade blend
X + 3y = 7
x = -3y + 7
2x + 4y = 8
2(-3y + 7) + 4y = 8
-6y + 14 + 4y = 8
-2y = 8 - 14
-2y = - 6
y = -6/-2
y = 3
x + 3y = 7
x + 3(3) = 7
x + 9 = 7
x = 7 - 9
x = -2
solution is (-2,3)
Answer:
12
Step-by-step explanation:
1/3 of 12 = 4
1/4 of 12 = 3
4 is 1 more than 3.
The number is 12.
_____
If this does not immediately come to mind, you can solve for the number, x:
x/3 -x/4 = 1 . . . . the difference between 1/3 of x and 1/4 of x is 1
x/12 = 1 . . . . . . . collect terms: (1/3 -1/4 = 4/12 -3/12 = 1/12)
x = 12 . . . . . . . . multiply by 12
