Answer:
- 30m +50 = 20m +100
- m = 5
- yes. symmetric property of equality.
Step-by-step explanation:
1. The expression for c in the first equation is (30m+50). Substituting that for c in the equation ...
c = 20m +100
gives you ...
30m +50 = 20m +100
__
2. Adding -50-20m to both sides gives ...
10m = 50
m = 5 . . . . . . . divide by 10
__
3. Doing the substitution in reverse, you would substitute (20m+100) for c in the equation ...
c = 30m +50
to get ...
20m +100 = 30m +50
This is the equation of part 1 with the expressions swapped to the other side of the equal sign. The symmetric property of equality tells you that changing sides of the equal sign does not change the value of the variable(s).
You get the same solution.

Step-by-step explanation:
y+43°= 180°( straight angle)
=>y= 180°-43°

Answer:
A percentage by definition means out of a hundred.
Anything out of a percent is anything out of a hundred.
In this case it’s 32 percent.
It’s just 32/100
When simplified you’d get 8/25
Both Ants start at the origin. Which means they will move the same distance even if they are going opposite waves
