The density is 4, and the mass is 12.
So we just plug this into the equation
d = m/v
4 = 12/v
We know that the volume must be 3 to make the equation true, because 12/4 = 3.
Therefore, the answer is F. 3 cm ^3
Answer:
C - 8
Step-by-step explanation:
153 - 81 = 72
72 ÷ 9 = 8
Answer:
x = -70
Step-by-step explanation:
x+47=−23
Subtract 47 from both sides.
x+47−47=−23−47
x = −70
Answer:
15x^2 - 14x - 8 = 0.
Step-by-step explanation:
(x - 4/3)(x + 2/5) = 0
Converted to integer values by multiplying the first bracket by 3 and the second by 5:
(3x - 4)(5x + 2) = 0
Expanding the brackets:
15x^2 + 6x - 20x - 8 = 0
15x^2 - 14x - 8 = 0.
