Solve for x.2 1/4x = 8 1/2

lorasvet [3.4K]

Answer:

$\large\boxed{x=3\dfrac{7}{9}}$

Step-by-step explanation:

$2\dfrac{1}{4}x=8\dfrac{1}{2}\qquad\text{convert the mixed numbers to the improper fractions}\\\\\dfrac{2\cdot4+1}{4}x=\dfrac{8\cdot2+1}{2}\\\\\dfrac{9}{4}x=\dfrac{17}{2}\qquad\text{multiply both sides by 4}\\\\4\!\!\!\!\diagup^1\cdot\dfrac{9}{4\!\!\!\!\diagup_1}x=4\!\!\!\!\diagup^2\cdot\dfrac{17}{2\!\!\!\!\diagup_1}\\\\9x=(2)(17)\\\\9x=34\qquad\text{divide both sides by 9}\\\\x=\dfrac{34}{9}\\\\x=3\dfrac{7}{9}$

Answer all question for brainliest

Neporo4naja [7]

Answer:

this shows that the height of 13 year old females in one class is less variable than the other class.
this means that the height of students in class with range 6 may vary from person to person while that in class with range 3 maybe clustered around one another.
we're expected to see students of almost same height in class ,with range 3, more than the students in class with range 6.

arranging the values in ascending order

2, 2, 4, 4, 4, 5, 6, 6, 6, 8, 8, 9

$mean = \frac{ sum \: of \: all \: observations}{total \: number \: of \: observations}$
