Answer:
12
Step-by-step explanation:
Answer:
16x
Step-by-step explanation:
Subtract the numbers: 9 - 5 = 4
Multiply the numbers: 
=16x
Let the weight of the first alloy will be x grams.
Weight of gold will be 0.1x grams, weight of lead will be 0.15x grams.
Let the weight of the second alloy <span>will be y grams.
</span><span>Weight of gold will be 0.3y grams, weight of lead will be 0.4y grams.
</span>Summarizing:
0.1x+<span>0.3y=60 - gold
</span><span>0.15x+0.4y=88 - lead
</span>
0.1x+<span>0.3y=60 * 10
</span><span>0.15x+0.4y=88 * 100
</span>
x+3y=600 * 15
15x+40y=8800
15x+45y=9000
<span>15x+40y=8800
</span>
<span>15x+45y=9000 /15
</span>45y-40y=9000-8800
x+3y=600
5y=200
x+3y=600
y=40
y=40
x=600-3*40=480
y=40
<span>x=480</span>
