Answer: a) 4 b) you could make up to 8 liters
Step-by-step explanation:
Since you need an isolated variable to use the substitution method, we need to re-arrange one of the equations. This will probably be easiest to do with the first one.
Add 5y to both sides of the first equation.
x=10+5y
Now, in the second equation, put in 10+5y in any spot that has an x.
2(10+5y)-10y=20
Distribute the 2 to both numbers in the parenthesis.
20+10y-10y=20
Combine like terms.
20=20
This means that the two equations are actually the same. You can see this if you multiply the whole first equation by 2
2(x-5y=10)
2x-10y=20, which is the same as the second equation. Therefore, the two equations are actually the same one.
Answer:
There are 40 milliliters of fruit juice in the bottle
Step-by-step explanation:
we know taht
20%=20/100=0.20
To find out the milliliters of fruit juice, multiply the volume of the bottle by the percentage of fruit juice in decimal form
so

therefore
There are 40 milliliters of fruit juice in the bottle
