Answer:

<h2>x = 6</h2><h2 />

Step-by-step explanation:

How many grams of an alloy containing 25% silver should be melted with 50 grams of an alloy containing 60% silver in order to ob
Kipish [7]

Answer:

20 grams of an alloy containing 25% silver has to be melted with 50 grams of an alloy containing 60% silver to obtain a final alloy containing 50% silver

Step-by-step explanation:

Hi

We define

A_{a}=50g @ 60\%, wich means alloy a has 50 grams containing 60% silver.

A_{b}=xg @ 25\%, wich means alloy b has x grams containing 25% silver.

So we can build an equiation 50 \times 0.60+x \times 0.25=\frac{1}{2}(50+x), as half of the final alloy has to be silver. Then solving for x

30+0.25x=25+0.5x\\30-25=0.5x-0.25x\\5=0.25x\\x=\frac{5}{0.25}=20

Wich means 20 grams of an alloy containing 25% silver (A_{b}) has to be melted with 50 grams of an alloy containing 60% silver (A_{a}) to obtain a final alloy containing 50% silver.

Solve for x.<br> −7≥13−5x
Sergio039 [100]

Answer:

\[=>x\geq 4\]

Step-by-step explanation:

Given inequality is \[−7\geq13−5x\]

Simplifying:

\[5x\geq13+7\]

\[=>5x\geq20\]

\[=>x\geq \frac{20}{5}\]

\[=>x\geq 4\]

Hence the solution for the given inequality is represented by  \[=>x\geq 4\]

This means that the original inequality will be true only for those values of x which are greater than or equal to 4.
