18.96 / 12 = 1.58
1.58 = the cost of 1 rose
1.58 X 5 = $7.9
Step-by-step explanation:
1. 2x - x + 7 = x +3 + 4
Collecting like terms;
2x - x - x = 3 + 4 - 7
2x = 0
x = 0
2. -2(x + 1) = -2x + 5
Expanding the bracket;
- 2x - 2= - 2x + 5
Collecting like terms;
- 2x + 2x = 5 + 2
0 = 7
It has no solution
3. 4x + 2x + 2 = 3x - 7
Collecting like terms;
4x + 2x + 3x = - 7 -2
9x = -9
x = -1
4. 4(2x + 1) = 5x + 3x + 9
Expanding the bracket
8x + 4 = 5x + 3x + 9
Collecting like terms
8x - 5x - 3x = 9 - 4
0 = 5
It has no solution
5. X + 2x + 7 = 3x - 7
Collecting like terms
x + 2x - 3x = - 7 - 7
0 = - 14
It has no solution
Answer: 5:15:23 pm
Step-by-step explanation:
There are different time zones in the world due to the Earth's rotation as this results in different parts of the Earth receiving sunlight at different times.
GMT is used as a basis to find the times of other zones.
In this instance, EDT time is -4 that of GMT.
This means that EDT is 4 hours behind GMT.
Time in GMT is therefore:
= 1:15:23 + 4 hours
= 5:15:23 pm
