___
0
- 5 = 3x
solve for x (division)
- 5 = 3x
___
3
-5/3 = x OR x = -5/3
Answer: C, because it is the only one that makes sense.
Divide both sides by eight
Answer:
y=x² +6
Step-by-step explanation:
This is the only 2nd-degree equation in the group: y = x² + 6. The others are linear equations.
Answer: 1 1/4 (1 whole and 1/4)
6 1/4 = 25/4
5 = 5/1
(25/4)/(5/1) = (25/4)*(1/5)
(25/4)*(1/5)
25/20
1 5/20 = 1 1/4
