Step-by-step explanation:
10.99 / 28 =
.3925
Which rounded up is .40
Answer:
see below
Step-by-step explanation:
19. -9 x = -117
20. -¹/₈ x = -³/₄
21. ⁵/₆ x = -⁵/₉
---------------------
19.
x = 117 / 9
x = 13
20.
x = ³/₄ divide ¹/₈
x = 6
21.
x = -⁵/₉ divide ⁵/₆
x = -²/₃
Simply because it is a right triangle and we can prove that using the Pythagorean theorem.
![{6}^{2} + {8}^{2} = {10}^{2} \\ 36 + 64 = 100 \\ 100 = 100](https://tex.z-dn.net/?f=%20%7B6%7D%5E%7B2%7D%20%20%2B%20%20%7B8%7D%5E%7B2%7D%20%20%3D%20%20%7B10%7D%5E%7B2%7D%20%5C%5C%2036%20%2B%2064%20%3D%20100%20%5C%5C%20100%20%3D%20100)
Basically, it passes the Pythagorean test. And we have it as a right triangle, with a right angle.
The answer is B) n+6. Simply because penny is 6 inches taller than Claire, which means you would have to add 6 inches to Claire's height to reveal penny's height. Also n represents Claire height which makes the expression easier to figure out.
