Answer:
The T-shirts cost $10 and the jeans cost $20.
Step-by-step explanation:
I guess you want to find the cost of the T-shirts and jeans at his first buy,
Let the cost be $t and $j for T-shirts and jeans respectively.
Then we have the system:
2t + j = 40...................(1)
and a month later:
0.5*2t + 0.5*5j = 60
t + 2.5j = 60................(2)
Multiply by - 2:
-2t - 5j = -120.............(3)
Adding equations (1) and (3):
-4j = -80
j = -80 / -4
j = $20.
Substituting j = 20 into equation (2):
t + 2.5(20) = 60
t = 60 - 50
t = $10.
t = $55
Answer:natural number that you can not get by multiplying two natural numbers
Step-by-step explanation:
Answer:
Domain: {4,5,7,10}
Range: {2,4,8}
Not a function
Step-by-step explanation:
The domain is all the x-values.
The range is all the y-values.
However, this isn't a function because two different inputs have the same output. If it were a function, there would be one unique output for every input.
Answer:
12y-282+8y=218
Step-by-step explanation:
3(4y-94)+8y=218
Distribute the parenthesis
12y-282+8y=218
Answer: The average annual rate of appreciation of the land over this 5-year period is 12%
Step-by-step explanation:
Calculating the amount of appreciation, we say,
$96,000 - $60,000 = $36,000
Then, $36,000/5 years = $7,200 per year.
Finally, $7,200/$60,000 = 0.12
0.12 x 100% = 12%
