Answer:
9 1/3
Step-by-step explanation:
1. Make 4 2/3 into a improper fraction
4 2/3= 14/3
2. Keep, change, flip
14/3 x 2/1
3. Multiply
14/3 x 2/1= 28/3
4. Simplify
28/3= 9 1/3
(btw keep, change, flip basically means to keep the first fraction the way it is, change the division sign to a multiplication sign, then flip the second fraction so the original denominator is the new numerator, and vise versa.)
Both Ants start at the origin. Which means they will move the same distance even if they are going opposite waves
There is a special kind of substitution which some books call it by comparison.
When the two equations are both
y=some function of x
y=some other function of x, then
we can substitute the second equation into the first giving
some function of x = some other function of x and start solving.
For example,
<span>y = –2x + 8
y = x – 1
substitute second into first
x-1=-2x+8
isolate x on left,
3x=9
x=3
second step is to substitute x=3 into second equation to get
y=x-1=3-1=2
Therefore the solution is (3,2)</span>
