Answer:
The number 3 is the stem.
The number 4 is the leaf.
Step-by-step explanation:
The Stem and Leaf Plot is a mathematical table used for the graphical representation of a data set. It involves splitting each data value into a stem (typically the first number, on the left) and a leaf (the last number, on the right).
The stem list is used for grouping data value downwards while the leaf values move rightward from its respective stem values and it's used for showing each data value within a group.
Also, the key of a stem and leaf plot is used as a guide on how to read the data set.
For example, the key for a stem and leaf plot is 3|4. Thus, the number 3 is the "stem" and the number 4 is the "leaf."
1 kilometer is 1000 meters
so, 5 times 1000 = 5000
5 kilometers is 5000 meters
it is 5000 meters from Kenny's house to Violet's house
Answer:
Step-by-step explanation:
By the triangle inequality theorem, the sum of the length of the two smaller sides must be greater than the length of the largest side. If 12 cm was the length of the largest side, notice that 
. Similarly, if x was the length of the largest side, we'd get the inequality 
. Combining these inequalities, we get 
.
7x + 4 = x - 2 -- (1)
To rewrite the equation above as a system, we simply let (1) be equal to y, i.e.
7x + 4 = x - 2 = y -- (2)
Recall from the rule of transitivity: If a = b = c, then this implies that a = c & b = c. From this, we have (2) to be expressed as
y = 7x + 4 -- (i)
y = x - 2 -- (ii)
Note: (i) & (ii) are both regarded as a system of linear equation which can be evaluated simultaneously.
