13t-13t=0
so your left with
6=12
which is a false statement which makes this equation have no solutions
Answer:
52 feet apart
Step-by-step explanation:
20 + 32 = 52
We have 60% and 85% antifreeze
We need 140 gallons of 70% antifreeze
x + y = 140
.60x + .85y = .70 * 140
X = 84 gallons 60%
Y = 56 gallons 85%
