Question 637596: What is the solution of x+3 divided by 6= 18?
What is the solution of 2b+4=30
A tank currectly holds 10 gals of water. It is being filled at the rate of 1/2 gal per min. How long will it take for the tank to hold 15 gal of water?
What is the solution of 6+2a=12? Justify each step.
SOLUTION
X+3/6=18
X+3=6*18
X+3=108
X=108-3
X=105

2) 2b+4=30
2b=30-4
2b=26
b=26/2
b=13
3) tank to hold 15 gal of water require 5 gal of water(15-10=5)
to fill 1/2 gal of water time require = 1 min
to fill 1 gal of water time require =1*2=2 min
therefore to fill 5 gal of water time require = 2*5= 10 min
4) 6+2a=12
2a=12-6
2a=6
a=6/2
a=3

X+3/6=18
X+3=6*18
X+3=108
X=108-3
X=105

2) 2b+4=30
2b=30-4
2b=26
b=26/2
b=13
3) tank to hold 15 gal of water require 5 gal of water(15-10=5)
to fill 1/2 gal of water time require = 1 min
to fill 1 gal of water time require =1*2=2 min
therefore to fill 5 gal of water time require = 2*5= 10 min
4) 6+2a=12
2a=12-6
2a=6
a=6/2
a=3
