Tim began with 40 comics
Further explanation:
The equation involve linear equation as there is only one object i.e. comic books
So,
Let x be the number of comic books Tim began with
Then after selling half comics Tim will have x/2 comics remaining
Now when he buys 16 more the expression will be:
He has total 36 books, then
Subtracting 16 from both sides
Multiplying 2 on both sides
<u>We can recheck, if he had 40, half of them will be 20 and adding 16 makes them 36.</u>

Lily has saved $ 7
<em><u>Solution:</u></em>
Given that bracelet costs $30
The bracelet Lily would like to buy costs $5 less than 5 times the amount she has saved
Cost of bracelet = $ 30
From given statement,
Cost of bracelet = 5 times the amount she has saved - 5
Let "x" be the amount saved by lily
Cost of bracelet = 5 times x - 5
Here "times" represents multiplication
30 = 5(x) - 5
30 = 5x - 5
30 + 5 = 5x
5x = 35
On dividing 35 by 5 we get 7
x = 7
Thus Lily saved $ 7
Answer:
118.1 meter
Step-by-step explanation:
by definition,
1 meter = 39.37 inches

3 meters = 39.37 x 3 = 118.11 = 118.1 meters (nearest tenth)
Answer:
Step-by-step explanation:
ahh this is a really tough one :D Does this happen to be an AP math class, Pineapple .. you are in advanced math :O.... good for you :)
sooo what can we set equal
note the lines have the same lenght, therefore the arc length will also be the same, then they give us the other two lengths to make the entire circle , yay
so then just set all the arc lengths equal to 360 °
(3x+ 30) + (3x + 30 ) + 2x + 4x = 360 ( put like terms together )
12x + 60 = 360 ( subtract 60 from both sides )
12x = 300 ( divide both side by 12 )
x = 25
nice we now know X :)
