That is correct
Step-by-step explanation:
Answer:
3rd option
Step-by-step explanation:
The range are the values covered on the y- axis
The lowest value is - 2
The highest value is 6
Both points have a solid circle on them indicating y can equal those values
range { y : - 2 ≤ y ≤ 6 }
First we define variables:
x = first card original value
y = second card original value
z = third card original value
We write the system of equations:
Andrew bought 3 baseball cards for $ 240:
x + y + z = 240
the first card (at its original value) along with the second card (at its original price) and got $ 320:
2x + y = 320
the first card (at its original value) card along with the third card (at its original price) would have only got him $ 280:
2x + z = 280
Solving the system we have:
x = 120
y = 80
z = 40
Answer:
The original prices for each of the 3 baseball cards is:
(120, 80, 40)
Answer:
(a) 1km
(b)80 fence panels
Step-by-step explanation:
(a) perimeter = 300+300= 600
200+200= + 400
=1000m
1km = 1000m
(b).
1panel = 2.5 m 1× 200÷2.5 = 80
=200m
Answer:
I think that the answer is A.
