7.2x - 8 = -29.6 that is your answer wrote out in numbers.
Answer:
I would stay direct vartation
Step-by-step explanation:
For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.
Answer:
K = 3
T = 2
And
H = 12
Step-by-step explanation:
3k = 9
k = 9/3
k = 3.
3k =k + 3t
subtitute value of k
3×3=3+3t
9-3=3t
6/3=t
t=2.
2k + h =18
2×3+h=18
h=18-6
h=12...
