Answer:
x =5
Step-by-step explanation:
transfer -2 to the other side it turns to +2
|2x-1|=7 +2
2x-1 =9
transfer -1 to the other side it turns to +1
2x=10
Divide both sides by 2
2x /2 = 10/2
x= 5
So 4 hours
1 hour=60 minutes
1 minute=60 seconds
1 hour=60 times 60 seconds=3600seconds
4 hours=3600 seconds times 4=14400seconds
so 8 out of 14400
8/14400=2/3600=1/1800
percent means parts out of100 so
x%=x/100
the reatios are equal to
1/1800=x/100
mulitply both sides by 100
100/1800=x
1/18=x
divide out
0.055555555=x
round
0.06%
Answer:
A =256 cm^2
Step-by-step explanation:
The perimeter of a square is 64 cm
P = 4s where s is the side length
64 = 4s
Divide by 4
64/4 = 4s/4
16 =s
The side length is 16 cm
The area of a square is
A = s^2
A = 16^2
A =256 cm^2
