Answer:

(49 - 29) + 1 =(50 - 29)

Step-by-step explanation:

The 20 comes from the subtraction of 29 in both sides of the previous step equality. In the following, I transcript the complete procedure and I add the step that you need to understand why 20 appears (in bold numbers):

29+20=49

49+1=50

(49 - 29) + 1 =(50 - 29)

20+1=21

50-29=21

hence, it was only nesseraty to subtract 29

Two different 2 digit numbers round to 70 to the nearest 10.The sum of the two numbers is 136.What could the two numbers be?

belka [17]

Answer:

Step-by-step explanation:

If they can be rounded to 70 to the nearest 10s. Then they are from 65 to 74.

Their sum is 136.

If we use 136 divided by 2 we get 68.

Since they're distinct, so one can be 67 and one can be 69

We solve 6 + 4

6 + 4 = 10.

Square root of 10:

$\boldsymbol { \sqrt{6 + 4} = \sqrt{10} }\\
\\
\\
\boldsymbol { \sqrt{10}l\underline{ \ 3.16227766017}}\\
\boldsymbol { \underline{- 10}l \ 3.16227766017 \times 3.16227766017 }\\
\boldsymbol { \ \ \ 00}$

The square root of 10 is a periodic decimal (decimal that has infinite decimals, worth the redundancy)

What is that periodic decimal?

$\boxed{\textbf{3.16227766017} \boldsymbol{ \ \Leftarrow }\textbf{Square root of 10}}$

REGARDS!
