Answer:
t=-2
Step-by-step explanation:
(t+9)20=140
Distribute the 20
20t +180 = 140
Subtract 180 from each side
20t +180-180 = 140-180
20t = -40
Divide by 20
20t/20 = -40/20
t=-2
Answer:
One solution x = 2
Step-by-step explanation:
Given the equation:
Multiply this equation by 2:
Use distributive property:
Combine the like terms:
Thus, this equation has one solution x = 2
16r^2+ 2r -4r
16r^2 - 2r
2r ( 8r -1)
Answer: x > 6
Step-by-step explanation: -4(2x+2) < -40
-8x - 8 < -40
+8 +8
-8x < 48
/-8x /-8x
x > 6 *The less than sign got flipped to a greater than sign because we divided by a negative.
