Evaluate 2p-3p/5r given that p=2,q=-2 and r=1
To evaluate the expression 2p - 3p / 5r, we need to substitute the given values of p, q, and r into the expression and perform the calculations step by step.
Given:
p = 2
q = -2
r = 1
Substituting these values into the expression:
2p - 3p / 5r = 2(2) - 3(2) / 5(1)
= 4 - 6 / 5
Now, let's perform the calculations based on the order of operations (PEMDAS/BODMAS):
4 - 6 = -2
Therefore, the expression simplifies to:
-2 / 5
Thus, the value of 2p - 3p / 5r, when p = 2, q = -2, and r = 1, is -2/5.
To evaluate the expression 2p - 3p / 5r, we substitute the given values of p, q, and r.
Given:
p = 2
q = -2
r = 1
Substituting the values:
2p - 3p / 5r = 2(2) - 3(2) / 5(1)
Simplifying the expression:
= 4 - 6 / 5
= -2 / 5
Therefore, the value of 2p - 3p / 5r, given p = 2, q = -2, and r = 1, is -2/5.
