5 pounds for 6.65 because you will get more pounds for a good amount of money.
A. 2x3=6 and 6x12=72 so 78 is greater than 36
6+72=79 which is less than 90
Substitute 8 for x in the function.
y=50(8)=400
He would travel 400 miles
Answer:
The answer to your question is: x = 7; y = 6
Step-by-step explanation:
2x+y=20 ( 1 ) Multiply by 5
6x−5y=12 ( 2 )
5 (2x+y=20) = 10x + 5y = 100
10x + 5y = 100
6x − 5y = 12 Eliminate y
16 x = 112
x = 112 / 16
x = 7
2(7) + y = 20 Substitution
14 + y = 20
y = 20 - 14
y = 6
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
