Answer:
x=4
Step-by-step explanation:
Because we know that PQ = RS, we can use the transitive property to replace PQ in the first equation with 29:
9x-7=29
1) Add 7 to both sides:
9x=36
2) divide by 9 on both sides:
x=4
18 - 2 = 16
8n = 16
Divide
N = 2
Determine whether the value is from a discrete or continuous data set. Number of coins in a jar is 78 number of coins in a jar is 78
Answer: Number of coins in a jar is from a discrete data set. Because the given variable is countable in a finite amount of time.
If a variable can take on any value between two specified values, it is called a continuous variable; otherwise, it is called a discrete variable.
Conversion factor is the term that is to be multiplied to a variable when converting between units. The conversion factor is: 
Given that:
From standard unit of conversion:
So, we have:
Cross multiply
Divide both sides by 1kg
Rewrite as:
Hence, the conversion factor is:
