Answer:
Step-by-step explanation:
First you need to get like items on the same side(put the variables on one side and the non-variables on the other). Remember anything you do on one side of the equal, you have to do on the other side, too.
5X+3=7X-1 I'm going to move the -1 first, but you don't have to as long as you keep the equation equal.
5X+3+1=7X-1+1 We know that +1-1 is zero and so is -1+1. So
5X+3+1=7X We don't need to keep that zero.
5X+4=7X Now, we want to move the 5X over.
5X-5X+4=7X-5X Simplify and get rid of the zero.
4=2X Last, we have to divide to get the 2 away from the X.
4/2=2X/2 Not everyone know that slash mean divide, :-).
2=X
It spins tilted on its axis, it spins every hour that's why we have 24 hours, day to night
100 cm = 1 meter
80 cm = 0.8 meter
200 meters/.8 meters = number of boards
250
Answer:
x=1
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Try B, hope that helps :)
