Explain how you would use estimation to solve this problem. be sure to include the number sentence you would
use to solve the problem.
51 + n=106

N= 55

Step-by-step explanation:

Adding 50 to 51 would equal 101.

51 + 50 = 101

So the answer is close to 50.

Now to solve:

51+N = 106

To solve for N, we want it by itself.

To do this, we want to get rid of 51. We can do this by subtracting 51 from both sides of the equation.

51+N = 106

-51         -51  

N      = 55

The 51 on the left side of the equation cancels out, so that only N is left.

On the other side of the equation, 106 - 51 is 55.

We can check this answer by plugging in 55 for N.

51+ N = 106

51+55 = 106

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
