Here's how to solve
Step-by-step explanation:
Okay so 13 -5
What can you add to 5 to get 13?
5+5=10
5+6=11
5+7=12
5+8=13
8 would be your answer.
There is decrease of 35% in the price of silver in the past 6 months.
<u>
Solution:
</u>
Given that
Price of silver went from $26.40 a troy ounce down to $17.16 a troy ounce during past 6 months need to represent this decrease in percentage
Price of silver before 6 months = initial price = $26.40
Price of silver now = current price = $17.16
Difference in price in 6 months = 26.40 – 17.16 = $9.24
Hence there is decrease of 35% in the price of silver in the past 6 months.
A-b=21
5a-2b=18
We can use substitution here. Take the first equation and solve for A. (Picking this one because it's easy)
a = 21+b
Plugin to the second equation:5(21+b)-2b=18
Simplify: 105 + 5b - 2b = 18
Simplify: 105 + 3b = 18
Subtract both sides: 3b = 18-105
Simplify: 3b = -87
Divide: b = -29
Plug back into the first: a=21+b
a = 21 - 29
a = -8
