It is 7 1/6 hope this helps
Answer:
The bags would weigh 27lbs. multiply 4 1/2 and6 and you get 27lbs.
Hello,
3/5x+19−3/20x−7/35x+19−3/20x−7;
(3/5-3/20-7/35-3/20)x+(19+19-7);
(3/5-3/20-1/5-3/20)x+31;
(12-3-4-3/20)+31;
2/20x+31;
1/10x+31;
Bye :-)
1)
x^2 + 4 = 0 Subtract 4 from each side
x^2 = -4
You cannot square a number to get a negative number. No real solution. (If you have learned about imaginary numbers, answer is 2i)
2)
<span>x^2+x-6=0 Factor. 3 and -2 add up to 1, and multiply to -6
(x+3)(x-2) = 0
Zero Product Property: Which numbers would put a zero in one of the parentheses?
x = -3 or x=2
3) </span><span>x^2-6x+7=0
Completing the Square:
Take half of b (-6), square it, and add/subtract that coefficient
x^2 - 6x + 9 - 9 + 7 = 0
(x -3)^2 - 2 = 0 Add 2 to both sides
(x-3)^2</span> = 2 Take the square root of both sides
<span>(x-3) = </span>√2 or -√2 Add 3 to both sides
<span>x = 3 + </span>√2 or 3 - √2<span>
