Answer
To find the value of T when m = -3, we substitute -3 into the equation:
T=4(−3)−11
Calculating this gives:
T=−12−11
Thus,
T=−23
Step 2
Make p the subject of the formula d = 3p + 4

Answer
We need to isolate p in the formula d = 3p + 4.
Start by subtracting 4 from both sides:
d−4=3p
Next, divide both sides by 3 to solve for p:
p=3d−4
