There could be five in each class.
Answer:
p = -2/5 or 3/8
Step-by-step explanation:
|5 − 3p| + 9 = 13p + 8
|5 − 3p| = 13p − 1
If 5 − 3p is positive:
5 − 3p = 13p − 1
6 = 16p
p = 3/8
If 5 − 3p is negative:
-(5 − 3p) = 13p − 1
-5 + 3p = 13p − 1
-4 = 10p
p = -2/5
Alternatively, we can square both sides of the equation:
(5 − 3p)² = (13p − 1)²
25 − 30p + 9p² = 169p² − 26p + 1
0 = 160p² + 4p − 24
0 = 40p² + p − 6
0 = (5p + 2) (8p − 3)
p = -2/5 or 3/8
Answer:
<em>16.00 grams/mole Oxygen * (1 mole/6.022x1023 atoms) = 2.66 x 10-23 grams. Any slight differences are due to the accuracy used for the atomic.</em>
<em> Step-by-step explanation:</em>
Answer: 6w^3 - 16w^7
Explanation:
2w^3(3 - 8w^4)
= 6w^3 - 16w^7
125 x .15 = 18.75
18.75 + 125 = 143.75
or
125 x 1.15 = 143.75
both work
the second method is easier (works for tax and tips)
