Answer:
3+6n=
Step-by-step explanation:
If you would like to solve the following system, you can calculate this using the following steps:
y = x - 20
y = 6 * x
_________
6 * x = x - 20
6 * x - x = -20
5 * x = -20 /5
x = -4
y = 6 * x = 6 * (-4) = -24
If you would like to solve the following system, you can calculate this using the following steps:
y = x + 20
y = 6 * x
_________
6 * x = x + 20
6 * x - x = 20
5 * x = 20 /5
x = 4
y = 6 * x = 6 * 4 = 24
Answer:
80%
Step-by-step explanation:
home work = 10%
project grade = 50%
final exam = 40%
so
<u>homework = 72</u>
100=10
72=? cross multiply and get 7.2%
<u>project grade = 80</u>
100 = 50
80 = ? cross multiply and get 40%
<u>final exam = 82</u>
100 = 40
82 = ? cross multiply and get 32.8%
then add them altogether getting a total of 80%.
