Answer:
<em>Riley has 72 tokens</em>
Step-by-step explanation:
<u>System of Equations
</u>
We have two conditions for the tokens Riley and Erik have earned. Let's call x and y to the number of tokens of Riley and Erik respectively. The first condition states that
Solving for y
The second condition is that the ratio of the number of tokens that Riley had to the number of tokens that Erik has is 8 to 7. It's written as
Or equivalently
Replacing y from the first equation
Operating
Simplifying
Riley has 72 tokens
Answer:
1.) C. 32
2.) Stem-and-leaf plot
Step-by-step explanation:
This is a stem-and-leaf plot. The stem represents tens and the leaves represent units. To make it easier to look at, it is equivalent to this:
- 20, 28, 29, 29, 31, 32, 36, 41, 42
Now, to find the mean, add up all the numbers and divide the sum by the number of values.
(20 + 28 + 29 + 29 + 31 + 32 + 36 + 41 + 42)/9 = 288/9 = 32
Answer:
find below
Step-by-step explanation:
7x-6 = 3x-14
4x = -8
x = -2
-2*7-6 = -14-6 = -20
-2*3-14 = -6-14 = -20
Answer:
the answer is 13. 6 is the correct answer
Volume/V=length x width x height
So, V=4.5 x 2 x 2
V =18
