Answer:
X = V/(YZ)
Step-by-step explanation:
V=XYZ
Division property of equality
V/(YZ) = X
Symmetric property of equality
X= V/(YZ)
13x-6+95=180
Combine like terms
13x=91
Divide by 13
X=7
Two base angles are supplementary/equal 180

Answer:
Shopkeepers gain just by weighing is 22.22%
Step-by-step explanation:
Explanation:
Assume that the shopkeeper bought x units of goods i.e. actual weight of goods.
As the balance used to buy goods weighs 10% more, he actually bought x×110100=1.1x weight units i.e. although the shopkeeper paid for x units, he actually bought 1.1x units by weight.
Now he has 1.1x units of goods, but for selling he uses another balance, which actually measures 10% less i.e. 1−0.10=0.9 units for each unit weight of goods sold.
So while selling 1.1x becomes 1.1x0.90=1.2222... units.
Hence, shopkeepers gain just by weighing is 22.22%
