Answer:
5, 7, 9
Step-by-step explanation:
Using the information given we get:
<em>Add 7 to both sides</em>
<em>Subtract 2x from both sides</em>
<em>Divide both sides by 3</em>
Using these equations:
and
We get:
Answer:
One has 4 sides and one has 3 sides
Step-by-step explanation:
a square has 4 sides and an equilateral triangle has 3 sides
The number of paychecks Jalen will have to save until he can purchase the laptop is 6
<h3>How many paychecks will Jalen have to save until he can purchase the laptop? </h3>
<u>Define your variable</u>
To do this, we use the following variables
- x represents the number of paychecks
- y represents the cost of the laptop
<u>Set up an equation, and solve it.</u>
In (a), we have:
- x represents the number of paychecks
- y represents the cost of the laptop
Using the above variables, the equation is:
y = 200 + 50x
The cost of the laptop is $500.
So, we have:
200 + 50x = 500
Evaluate the like terms
50x = 300
Divide by 50
x = 6
Hence, the number of paychecks Jalen will have to save until he can purchase the laptop is 6

Answer:
$ 1250
Step-by-step explanation:
output = 50 units per day
average total cost = $ 60
total cost = output × average total cost =50 × 60 = $ 3000
total variable cost = output × average variable cost = 35 × 50 = $ 1750
total cost = total fixed cost + total variable cost
total fixed cost = total cost - total variable cost = $ 3000 - $ 1750 = $ 1250
