Answer:
1/6 x + 27 combine like terms to get the answer :)
Step-by-step explanation:
(85 + 84 + 78 + x) / 4 = 86
(247 + x) / 4 = 86
247 + x = 86 * 4
247 + x = 344
x = 344 - 247
x = 97 <=== her score was 97
<span>3√96 * √98 = </span><span>12√6 * 7√2 = 84</span>√12 = 168√3
The estimate would be 430000
___-1=10-3
x-1=10-3
x-1=7
x=8
therefore the blank is 8
