Answer:
16
Step-by-step explanation:
Let the unknown number be x
2x - 7 = 9
2x = 9 + 7
2x = 16
2x÷2 = 16÷2
x = 8
8x2
=16
Answer:
65 adult tickets and 135 student tickets were sold.
Step-by-step explanation:
4s + 6a = 930
s + a = 200
s = -a + 200
4(-a + 200) + 6a = 930
-4a + 800 + 6a = 930
2a + 800 = 930
2a = 130
a = 65
There were 65 adult tickets sold.
200 - 65 = 135
There were 135 student tickets sold.
Check:
4(135) + 6(65) = 930
540 + 390 = 930
930 = 930
Sounds like you're more interested in being given answers than you are in receiving help and guidance towards finding your own answers.
I will give you one answer and ask you to find the other two.
First, rearrange the given data 3 2 6 4 5 3 4 2 7 5 3 in ascending order. Since you have 11 data points, merely choose the point in the exact middle (that is, the 6th point). That's your "median" for this data set.
Your turn: look up "mean" and share the definition you find. Do the same for "mode."
Supposing you sum up the 11 data points and divide that sum by 11. What would this give you? What's its name?
Write a proportion
centimeters / kilometers
1.5 / 45 = 0.8 / x
cross multiply
(1.5 * x ) = (45 * 0.8)
1.5x = 36
divide both sides by 1.5
x = 24
The actual distance between the two points is 24 kilometers.
Hope this helps
Answer:
218
