8 2/3
because 6 1/2 divided by 3/4 is 8 2/3
Well i havent read the story but from context clues id say its B
Answer:
Step-by-step explanation:
1. 10² + 7² = x²
149 = x²
x = √149
2. x² + 19² = 21²
x² = 21² - 19² = 80
x = √80 = 4√5
3. x² + 16² = 27²
x² = 27² - 16² = 473
x = √473
4. 5.3² + 12.8² = x²
191.93 = x²
x = √191.93
5. 9² + 20² = x²
481 = x²
x = √481
6. 31 = x + 2√(19²-17²) = x + 2·6√2 = x + 12√2
x = 31 - 12√2
The answer is B.
14 + 15x
14 + 15(5)
14 + 75
89
Uh it can really be anything. You should try and be more specific: see if you did the whole problem.
