Answer:
X= - 2
Step-by-step explanation:
-3 (5x+6) - 3x = 6-6x
Remove the parentheses
-15x-18-3x=6-6x
Collect the like terms
-18x-18=6-6x
Move the variable to the left-hand side and change its sign
18x+6x=6+18
-12x=24
Divide both sides
X=-2
- 3(5x + 6) - 3x = 6 - 6x
- 15x - 18 - 3x = 6 - 6x
- 18x - 18 = 6 - 6x
[Transforming the like terms in same side]
- 18x + 6x = 6 + 18
- 12x = 24
x = - 24/12 = - 2.
True!
67/24
that is what my graphing calculator got, I hope its right
x > -6.
16x - 33x < -12x + 30
Add 12x to both sides:
16x - 33x + 12x < 30
-17x + 12x < 30
-5x < 30
x > 30/-5
x > -6
(Note the inequality signs flips because we are dividing by negative 5).
distance = speed x time
distance = 2.35 x time
distance = 2.35 x 5
distance = 11.75 feet in 5 minutes
