Solve the system by the elimination method.
2a + 3b = 6
5a + 2b - 4 = 0
multiply thru the top equation by 2
Multiply thru the bottom equation by 3
4a + 6b = 12
15a+ 6b = 12
Subtract and solve for "a":
11a = 0
a = 0
Solve for "b" using 2a + 3b = 6
2*0 + 3b = 6
b = 2
The given sequence is a geometric sequence. The property of geometric sequence is that each term is multiplied by a specific number known as "common ratio" to get the next term. In this case the common ratio is 1/2.
2 x 1/2 = 1
1 x 1/2 = 1/2
1/2 x 1/2 = 1/4
and so on..
19 students ride bikes.
(950 x 0.02 = 19)
Hope this helped!
V=(4/3)r^3
first one
V=(4/3)(1/2)^3
V=4/24
V=1/6
V=(4/3)(3/4)^3
V=108/192
V=9/16
compare
1/6 to 9/16
16/96 compared to 54/96
well, the bigger ballon is 19/8 ft^3 bigger than smaller oe
