Decimals- do i move the decimal when adding or multiplying
EastWind [94]

Answer:

when adding you just line the decimals up like this, let's say you had to add 1 to 2.58.

2.58

+ <u> 1 .00</u>

3.58

when multiplying you might have to move it, say you had to multiply 1.5 by 2.2. (you don't have to line up the decimals like with addition)

1 .5

<u> </u><u>×</u><u> 2.2</u>

30

<u> </u><u>+</u><u> 300</u>

3.30

1.5 has one decimal place and 2.2 also has one decimal place so you put those 2 decimal places in your answer.

sorry if this is a bit confusing lol

What is the Angles of the triangle?

The sum of the two interior angles that are not adjacent to it equals the exterior angles of a triangle, but the interior angles of a triangle always add up to 180°. Subtracting the angle of the desired vertex from 180° is another method for determining a triangle's exterior angle.

<h3>Suppose point C is where lines DE and AB converge.</h3>

∠ACE = (2x+2)°

∠ECB = (5x+ 3)°

Angles ACE and ECB are additional angles according to the linear postulate, as seen in the attached diagram.

Therefore:

∠ACE+∠ECB = 180°

(2x+2)+(5x+3) = 180

2x+ 5x+ 2+ 3 = 180

7x + 5 = 180

7x = 175

x= 175/7

x = 25

Thus the value will be  = 25

Tania measured the growth of her plant each week. The firstt week, the plant's height measured 2.65 Decimeters. During the secon
Evgesh-ka [11]

Answer:

3.35 decimeter.

Step-by-step explanation:

We have been given that the first week, the plant's height measured 2.65 Decimeters. During the second week, Tania''s plant grew 0.7 Decimeter.

To find the height of Tania's plant at the end of second we will add 0.7 to 2.65.

\text{The length of Tania's plant at the end of 2nd week}=2.65+0.7

\text{The length of Tania's plant at the end of 2nd week}=3.35

Therefore, Tania's plant was 3.35 decimeter tall at the end of 2nd week
