Step-by-step explanation:
Answer: N=3
Step-by-step explanation:
Let's represent notebooks with "N" and pencils with "P".
Then,
N + P = 4.50
Since N =2P, we can substitute that directly into the equation:
(2P) + P = 4.50
3P = 4.50 (divide both sides by 3)
P = 1.50
Now that we have P, we can in turn substitute that into the equation.
N + (1.50) = 4.50
N = 3.00
Answer:
Step-by-step explanation:
(2x-5)(x+6)=0
either 2x-5=0 Or, x+6=0
2x-5=0
2x=0+5
x=5/2
x+6=0
x=0-6
x=-6
so x=5/2 , x=-6
