Answer: 11
Step-by-step explanation:
From the question,
a = first term= 2
3rd term = a + 2d = 4
2 + 2d = 4
2d = 4-2
2d = 2
Commons difference = d = 2/2 = 1
10th term = a + (n-1)d = a + (10-1)d = a + 9d
= 2 + 9(1)
= 2 + 9
= 11
The 10th term is 11
Answer:
Area of land: 800 miles.
Step-by-step explanation:
Since the map is a square, you can assume that all 4 sides will equal 8 inches. (Giving you a perimeter of 32, and an area of 64.) Since each inch corresponds to 5 miles, you multiply 8 by 5 which equals 40.
Answer:
no solutions
Step-by-step explanation:
3x - 6y= -12
x - 2y= -8
Solve the second equation for x
x-2y=-8
Add 2y to each side
x-2y+2y = -8+2y
x = -8+2y
Substitute this into the first equation every place to see x
3x-6y=-12
3(-8+2y) -6y=-12
Distribute the 3
-24 +6y -6y =-12
-24 = -12
Since this is never true there are no solutions.
