Charge of the electrons. the electric current is produced when electron move from one position to another position.
We have to find out the number of trees planted per unit rate of time.
Kyla can plant 300 trees in 1 hour, so she can plant 300 trees in 3600 seconds. This implies that she can plant
trees per second.
On the other hand, Mia can plant 1 tree in 13 seconds, so she can plant
trees per second.
Working together they can plant
trees per second, i.e. it takes them 156/25 seconds to plant a tree.
We conclude that they plany 100 trees in
seconds
Answer:
x= - 35 over 89
Step-by-step explanation:
Step 1: Simplify both sides of the equation.

x−23=18x−18
Step 2: Subtract 18x from both sides.

x−23=−18
Step 3: Add 23 to both sides.

x=5
Step 4: Multiply both sides by 7/(-89).

Answer:
In 4 months
Step-by-step explanation:
If you keep subtracting 140nfrom 3440 u will get 2880 after you do that 4 times. If you keep adding 220 to 2000 you will get 2880 after you do it 4 times.
