Answer:
5/2 kg
Step-by-step explanation:
The ratio here is 2:6. 2 plus 6 is 8.
Then (2/8) times 10 kg represents the amount of compost needed; that comes to 20/8 kg, or 10/4 kg, or 5/2 kg.
The smallest the absolute value will ever be is zero so the left side won't ever be smaller than -2 so won't ever be less than -3.
D. No solution

To factor -1/8 out you need to find a number that multiply by -1/8 be equal to each term in the expression.
To find those numbers you divide each term into -1/8:

Then, the factors are:
Uh... What diagram? I cant understand what you are tryimng to ask if i dont even know where the diagram is. Just saying.
Answer:
7
Step-by-step explanation:
[(1/3 – 1/9)² + (1/3)³] : (1/3)⁴
Next, we shall simplify (1/3 – 1/9)². This is illustrated below:
(1/3 – 1/9)² = ((3 – 1)/9)² = (2/9)²
[(1/3 – 1/9)² + (1/3)³] : (1/3)⁴
= [(2/9)² + (1/3)³] : (1/3)⁴
= [4/81 + 1/27] : 1/81
= [(4 + 3)/81 ] : 1/81
= 7/81 : 1/81
= 7/81 ÷ 1/81
Invert
= 7/81 × 81/1
= 7
