Answer:
A) The following are true:
2+4x=2(2x+1)
2+4x=2⋅2x+2⋅1
2+4x=4x+2
2+4x−4x=4x−4x+2
2=2
B)

Answer:
It will take Abbey 10 seconds to move 8.5 meters
Step-by-step explanation:
100 cm makes one meter
So 85 cm=85/100
85 cm. = 0.85 meter
So Abbey travels 0.85 meters every second
One second= 0.85 meters
Let the unknown time be x
X= 8.5 meters/0.85
X= 10 seconds
It will take Abbey 10 seconds to move 8.5 meters
Answer: d<−3
Step-by-step explanation:
Step 1: Subtract 8 from both sides.
−7d+8−8>29−8
−7d>21
Step 2: Divide both sides by -7.
−7d/7>21/-7

For this item, we represent the very original value or price of the given item by x such that increasing the retail price by 40 percent will give us 1.4x. Also, when the retail price of the item is reduced by 25 percent, we have.
new retail price = 1.4x (1 - 0.25) = 1.05x.
This means that the new retail price is only 5% over the manufacturer price.
