The answer to the question
What we know:
Lot= 21 x 30ft
Perimeter=2l+2w
Want to put 4 corner post and one post every 3 ft
What we need to find:
How many post we need.
Perimeter=2 (21)+2 (30)=42+60=102ft
102/3=34
34 posts are needed.
Answer:
x = 7
Explanation:
We are given
22 + 54x = -20 + 60x
We can add 20 on both sides using the Addition Property of Equality
42 + 54x = 60x
Subtract both sides by 54x using the Subtraction Property of Equality
42 = 6x
Divide both sides by 6 using the Division Property of Equality
x = 7
Answer:
7
Step-by-step explanation:
The two person will pay the same amount of money when they both watch 9 hockey games.
<h3>How to find the equation and use it to find cost?</h3>
A hockey season ticket holder pays $99.00 for her tickets plus $3.00 for a program for each game. Therefore,
y = 99 + 3x
where
y = total cost
x = number of game
A second person pays $14.00 for a ticket to every game but doesn't buy programs. Therefore,
y = 14x
The number of games they will have the same amount is as follows:
99 + 3x = 14x
99 = 14x - 3x
99 = 11x
x = 99 / 11
x = 9
Therefore, they will have the same amount when they watch 9 games.
