Sn=n/2 (2a1 +(n-1)d)

[s5= 5/2 (2a1 +(5-1)d) = 5a1+10d]

s6=3(2a1+5d) = 6a1+15d
s4=2(2a1+3d) = 4a1+6d

6a1+15d -(4a1+6d) = 5 -----(1)

s7=7/2(2a1+6d) =7a1+21d

6a1+15d + 7a1+21d = 21 -----(2)

(1) 2a1+9d=5 -----(3)
(2) 13a1+36d=21 ----(4)

(3)*4 ; 8a1+36d=20 ----(5)
(4)-(5) 5a1 = 1
so a1 = 1/5

(3) 2a1+9d=5
2(1/5)+9d = 5
9d = 5-2/5 =23/5
d = 23/45


so [s5= 5/2 (2a1 +(5-1)d) = 5a1+10d = 5(1/5) + 10(23/45) = 1 + 5.11 = 6.11 ]

i'm not sure about the answer but the process is correct

12. A red drone is 100 feet off the ground and is rising at 8 feet per second. A blue drone is 180
Harrizon [31]

Answer:

The red drone will be at the same height as the blue drone at 33.33 seconds, therefore higher at 34 seconds.

Step-by-step explanation:

Red drone = 100 + 8*seconds

Blue drone = 180 + 5*seconds

100 + 8*seconds = 180 + 5*seconds

3*seconds = 100

seconds = 33.33

nataly862011 [7]

Answer:

1 centimeter on the map=125 meters

Step-by-step explanation:

We need to find how many meters for 1 centimeter, because that is the lowest value.

So, divide 8 by 8 to get 1 centimeter.

To get its equal distance, divide 1000 by 8 as well.

1000/8=125

Hope this helps!
