-3 2/3 I just changed the mixed number into a improper fraction
<span>2 Li(s) + O2(g) = 2 LiO is the balanced equation</span>
A-2b=-10
add 2b on both sides
a=2b-10
add 10 to both sides
a+10=2b
divide both sides by 2
a/2+10/2=a/2+5=b
b=5+a/2
Ordered pairs that work for this direct variation are (4, 3), (8, 6) and (12, 9).
In order to find these, we must first find the value of the direct variation coefficient. We can do that using the base equation y = kx and then by plugging in to find k.
y = kx
12 = k(16)
3/4 = k
Now that we have k, we can model the equation as y = 3/4x. We can also find any number of ordered pairs by using the x value and finding the y value. All of the above answers work.
Andrew walked for 3/4 miles after his break
<h3>
How to calculate the number of miles Andrew walked after the break ? </h3>
Andrew went for a walk
The trail he took is 1 1/4 miles long
He walked for 1/2 miles before stopping for a water break
After the break, he continued the journey
He continued the journey without stopping
The distance Andrew walked after his break can be calculated as follows
5/4 - 1/2
= 5-2/4
= 3/4
Hence Andrew walked for 3/4 miles after taking the break
