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

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153

he answer is x=1x3 because x=1 to x=3
