Answer:
let w = amt of water required
:
An equation based on the the percent water, an 80% solution is 20% water.
.20(320-w) + w = .50(320)
64 - .2w + w = 160
.8w = 160 - 64
w = 96%2F.8
w = 120 gal of water to produce 320 gal of 50% antifreeze
:
320 - 120 = 200 gal of 80% solution
Water: _120___ gallons
Premium Antifreeze: __200___ gallons
Step-by-step explanation:
Answer:No it is not proportional
Step-by-step explanation:
The reason non proportional is not proportional is bc it's not proportional.
Answer:
see below
Step-by-step explanation:
Putting each equation in standard form is a good start.
1. Divide the first equation by 2. Divide the second equation by -5.
2. Divide the first equation by 2; multiply the second by -1.
3. Divide the first equation by 2.
4. Divide the first equation by 2.
5. Divide the first equation by 2.
