Answer:
-1 < c < 9
Step-by-step explanation:
-6<2c-4<14
Add 4 to all sides
-6+4<2c-4+4<14+4
-2<2c<18
Divide by 2
-2/2<2c/2<18/2
-1 < c < 9
Answer: 33 mph
Step-by-step explanation:
First find out what 40% of 55 is:
= 40% * 55
= 22 mph
This means that the speed reduces by 22 mph inside the city.
The speed inside the city is therefore:
= 55 - 22
= 33 mph
Given:
are in geometric sequences.
To find:
The value of x.
Solution:
If a, b, c are in geometric sequences, then

...(i)
It is given that
are in geometric sequences. By using (i), we get




On further simplification, we get



Therefore, the value of x is 0.
Answer:
Mmm either B or D one of those two
