6 3/4 - 1 2/3
We can convert the fractions to decimals, and if the decimals are bigger than .5, we can round up to the nearest whole number.
3/4= .75 <== we can round up to the nearest whole number
6.75= 7
2/3= .66666 <=== we would also round this up to the nearest whole number
1.66666= 2
7-2 <=== estimated expression
I hope this helps!

Answer:
The value of r is 105
Step-by-step explanation:
Quadratic equation helps us to solve any quadratic equation. The formula is:
(-b ± √b² - 4ac) ÷ 2a
For the quadratic equation ax²+bx+c
For the equation: X² - 9x - 6:
a = 1, b = -9 and c = -6
Replacing in the quadratic formula:
(-(-9) ± √(-9)² - 4(1*-6)) ÷ 2*1
= 9 ± √105 / 2
<h3>That means, the value of r is 105</h3>
