Answer:
6t = -21
Step-by-step explanation:
To find the 6t, we would first have to find t. To find t, we can solve for t in the equation 3t - 7 = 5t.
3t - 7 = 5t
Subtract 3t from both sides to get rid of the 3t on the left side.
-7 = 5t - 3t
Simplify.
-7 = 2t
Divide both sides by 2 to get rid of the coefficient of 2 on the right side.
-7/2 = t
t = -7/2
Now we found that t = -7/2. To find 6t, plug in -7/2 for t.
6(-7/2) = -21
So 6t = -21.
I hope this helps. :)
Answer:
6t = -21
Step-by-step explanation:
3t-7 = 5t simplifies by subtracting 5t on both sides, then adding 7 on both sides:
3t -5t -7 +7 = 5t-5t+7
-2t = 7
t = -7/2
Then 6t = 6*-7/2 = -21

Answer:
Step-by-step explanation:
V = L*w*h
L = 3
w = 2
h = ?
V = 24
24 = 2*3 * h Combine the right
24 = 6* h Divide both sides by 6
24/6 = 6h/6
4 = h
Answer: Both plants grow at same rate ie., 4/3 cm per day
Step-by-step explanation:
8 cm = 6 days
1 day = 1/6 x 8 = 4/3 cm
12 cm = 9 days
1 day = 1/9 x 12 = 4/3 cm
