Answer:
Depends on the starting number
Step-by-step explanation:
Answer:
We can use linear system of equation with one variable.
Step-by-step explanation:
It is given that,Nina is 10 years younger than Deepak.
Deepak is 3 times as old as Nina.
<u>To solve this using linear equation</u>
Let d be the age of Deepak and n be the age of NIna
we can write,
n = (d - 10) ---(1)
d = 3n
d = 3(d - 10) --------(2)
d = 3d - 30
3d - d = 30
2d = 30
d = 30/2 = 15
n - d - 10 = 15 - 10 = 5
Therefore the age of Deepak = 15 and age of Nina = 5
You can only buy 1 CD using $12 because $12 minus $8 is $4 and $4 is not enough for another CD.
<em>From the information given above, </em><u><em>D is the answer</em></u><em> which has a constant proportionality equal to 1. </em>
