Answer:
p = -14
Step-by-step explanation:
5/7p - 2/7p + 12 = 6
Combine like terms
3/7 p +12 = 6
Subtract 12 from each side
3/7p + 12-12 = 6-12
3/7p = -6
Multiply each side by 7/3
7/3 * 3/7p = -6*7/3
p = -14
Answer:
x=-3
y=2
Step-by-step explanation:
To solve this problem you can use the elimination method:
- Multiply the second equation by -6:
- Add both equations:
- Substitute the value of x into one of the original equations and solve for y:
(a) 8(4x+3) > -1 + 7x
32x + 24 > -1 + 7x
32x - 7x > -1 -25
25x >-26
x > -26/25
(b) 167 < 6 + 7(2 - 7r)
167 < 6 + 14 - 49r
49r < 6 + 14 - 167
49r < - 147
r < - 3
(c) 8x + 40 > -8 ( 1 - 7x)
8x + 40 > -8 + 56x
56x - 8x < 48
48x < 48
x < 1
(d)5( 6 + 3r) + 7 > 127
30 + 15r + 7 > 127
15r > 127 - 37
15r > 90
r > 6
Answer:
The Subjects: The subject of this research are the drivers who were selected randomly to take part in the experiment
The Treatment: The treatment for this research will therefore be driving and also talking on a cell phone at the same time and also driving while not talking on the phone
