Answer: 11
Explanation:
Solve 5 + squrt(36)
Since 6x6 is 36, the square root of 36 is 6.
5+6
Result: 11
8/9 because there are 36 inches in a yard and you need to convert all the yards to inches and turn it into a fraction. The original fraction is 192/216 but it simplifies to 8/9.
First you have to find slope (m)
m = (y2 - y1) / (x2 - x1)
m = (-1 - 4) / (2 - 3)
m = (-5) / (-1)
m = 5
now you have to use point-slope
y - 4 = 5 (x - 3)
y - 4 = 5x - 15
y = 5x - 11 is your answer
68/50 because you need to find a common denominator which in this case would be 50, then multiply the second fraction add up the two then that is your answer.
X= grade on next test
Add up all scores, divide by 6 and this equals the average of 84
(86 + 91 + 86 + 61 + 87 + x)/6= 84
add in parentheses
(411 + x)/6= 84
multiply both sides by 6
411 + x= 504
subtract 411 from both sides
x= 93
ANSWER: 93 is needed on the next test to have an average of 84
Hope this helps! :)
