Answer:

The solution of inequality as x>-\frac{5}{4}

Step-by-step explanation:

 Given inequality 0.2(x + 20) – 3 > –7 – 6.2x

We have to solve the given inequality

Consider 0.2(x + 20) – 3 > –7 – 6.2x

Multiply both side by 10, we have

0.2\left(x+20\right)\cdot \:10-3\cdot \:10>-7\cdot \:10-6.2x\cdot \:10

on simplifying, we get,

2\left(x+20\right)-30>-70-62x

Expand by multiplying 2 , we get,

2x+40-30>70-62x

2x+10>70-62x

Subtract 10 both side, we get,

2x+10-10>-70-62x-10

Simplify, we get,

2x>-62x-80

Add 62x both side, we get,

2x+62x>-62x-80+62x

Simplify , we get,

64x>-80

Divide both side by 64, we get,

\frac{64x}{64}>\frac{-80}{64}

Simplify , we get,

x>-\frac{5}{4}

Thus, the solution of inequality as x>-\frac{5}{4}

How many L of an 85% alcohol solution must be mixed with 6 L of a 55% alcohol solution to make a 65% solution?
zepelin [54]

Answer:

3 Liters of the 85% Solution

Step-by-step explanation:

You have to draw your buckets. I can't on computer so imagine the fraction bar is the bottom of the buckets.

\frac{85}{x}+\frac{55}{6}=\frac{65}{x+6}

Then we multiply the top of the buckets with the bottom:

85x+330=65x+390

Now we simplify and solve

20x=60

x=3

You need 3 liters of the 85% solution!
