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
The answer is D. The triangles have proportional sides (the triangle on the left has sides that are 4 times that of the triangle on the left). Since the triangles have proportional sides, the angles given will also be equal. Thus, we can show their similarity through both the SSS and SAS similarities.
Answer:

If we call the number "x" then:
x*25%=21
x*25/100=21
x=21*4
x=84
