Answer:
n = 2 and a = - 4
Step-by-step explanation:
(1)
- 4n - 8 = 4(- 3n + 2) ← distribute parenthesis
- 4n - 8 = - 12n + 8 ( add 12n to both sides )
8n - 8 = 8 ( add 8 to both sides )
8n = 16 ( divide both sides by 8 )
n = 2
(2)
a - 15 = 4a - 3 ( subtract a from both sides )
- 15 = 3a - 3 ( add 3 to both sides )
- 12 = 3a ( divide both sides by 3 )
- 4 = a
Answer:The slope is -1/7
Step-by-step explanation:
2-3=-1
3-(-4)=7
-1/7
Answer:
D. Division Property of Equality
Step-by-step explanation:
Divided both sides by 0.36 to make x the subject
Answer:
x +5x-6 ≤ 12
x +5x-6+6 ≤ 12+6
6x ≤ 18
6x ÷ 6≤ 18 ÷ 6
x≤3
Step-by-step explanation:
- add 6 to both sides
- add like-terms
- divide both sides by 6 to get x
Step-by-step explanation:
Bigger -smaller
