Answer:
Answer: 10.875
Step-by-step explanation:
Let the short side be x.
Then the long side is 3x.
There are two opposite sides of each length, so the perimeter is
3x + 3x + x + x = 8x
The perimeter is 29, so we get the equation
8x = 29
Solve for x by dividing both sides by 8.
x = 29/8
x = 3.625
The longer side is 3x.
3x = 3(3.625) = 10.875
Answer: 10.875
Answer: Each have to sell 91 candy bars to have the same amount of money.
Step-by-step explanation: Suppose x represents the amount of candy bars.
Team A already have $165 and they are selling each candy bar for $2. The mathematical equation that represents the amount of money they have is
A: 165 + 2x
Team B initially has $74 and will sell each candy bar for $3. Then, the mathematical equation representing their amount of money is
B: 74 + 3x
So, to have the same amount of money:
165 + 2x = 74 + 3x
x = 165 - 74
x = 91
<u>Teams A and B will have the same amount of money when each of them </u><u>sell 91 candy bars</u>.
If the total cost was 21.35, and the poster cost 8.95, then all you need to do is subtract to poster cost from the total cost to find the cost of the pencil.
21.35-8.95= $12.40
You can either make a table using any numbers you would like (I would suggest -5 to 5) and then graphing the rule
ex. (7/2)(-5)-2 = -19.5 (I multiplied (7/2) by -5 and then subtracted 2)
Or you can put the rule in a graphing calculator and check the points from there
