One canned juice drink is 20% orange juice, another is 5% orange juice, how many liters of each should be mixed together in orde

gavmur [86]

Answer:

11 L of 20% juice and 4 L of 5% juice

Step-by-step explanation:

Let

x L = amount of 20% juice

y L = amount of 5% juice

20% juice:

Amount = x L

Amount of juice $=0.2x$ L

5% juice:

Amount = y L

Amount of juice $=0.05y$ L

16% juice:

Amount = 15 L

Amount of juice $=0.16\cdot 15=2.4$ L

We mixed x L of 20% juice with y L of 5% juice to get 15 L of 16% juice, so

$x+y=15$

and

$0.2x+0.05y=2.4$

From the first equation:

$x=15-y$

Substitute it into the second equation:

$0.2(15-y)+0.05y=2.4\\ \\20(15-y)+5y=240\\ \\300-20y+5y=240\\ \\-20y+5y=240-300\\ \\-15y=-60\\ \\15y=60\\ \\y=4\ L\\ \\x=15-4=11\ L$

X+5.6+6.3+8.4=27.4 What’s the answer and how do I solve this equation?

adoni [48]

Answer:

X= 7.1

Step-by-step explanation:

x+5.6+6.3+8.4=27.4

Step 1: Simplify both sides of the equation.

x+5.6+6.3+8.4=27.4

(x)+(5.6+6.3+8.4)=27.4(Combine Like Terms)

x+20.3=27.4

Step 2: Subtract 20.3 from both sides.

x+20.3−20.3=27.4−20.3

x=7.1
