: 3 = 5 : 30
Answer:
7.31 and 0.685
Step-by-step explanation:
x^2 -8x +5 = 0
use the quadratic formula
- (-8) + √(-8^2 -4(1)(5) / 2(1(
(8 + √(64 -20))/2
(8+√44)/2
8+6.63 / 2
14.63/2= 7.31
+7.31
(8- √44)/2 = 0.685
If you have to write the equation then it would be "5k + 6.7"
1 7/9 - 4/9
Convert 1 7/9 to an improper fraction:
16/9 - 4/9
Subtract the numerators together:
12/9
Convert to a whole number:
1 1/3
It is between 3.1 and 3.17 or 3.2 if you want it by hundredths.
This is because 3.16 is 3.1600000 and many more zeros but 3.16227766 is slightly over that so it would be between 3.1 and 3.17.
