You just add the thickness of the 2 books which is 237+3.56=240.56
Then you round the hundredth place which is 5 and next to it is the number 6 and that’s 5+ so it’s going up by a number. The answer is 240.6 inches tall. I tried explaining it well so sorry if you didn’t understand.
Answer:
6x + 2 ( x - 4) = 8 + 4 ( x + 2)
6x + 2x - 8 = 8 + 4x + 8
<em><u>Arranging</u></em><em><u> </u></em><em><u>like</u></em><em><u> </u></em><em><u>terms</u></em><em><u> </u></em>
6x + 2x - 4x = 8 +8 - 8
8x - 4x = 8
4x = 8
x = 8/4
x = 2

Answer:
not sure!!
Step-by-step explanation:
If the mean height of 15 girls is 1.65m, the sum of the girls’ heights is 15×1.65=24.75m.
If the mean height of 10 boys is x metres, the sum of the boys’ heights is 10x m.
The sum of all 25 srudents’ heights is 25×1.682=42.05m.
Therefore, 24.75+10x=42.05, x=(42.05-24.75)/10=1.73m, the mean height of the boys.
