Answer:

Step-by-step explanation: x + 1 = 9x - 3

x + 1 = 9x - 3

(minus x from both sides)

1 = 8x -3

(add 3 to both sides)

4 = 8x

(flip the equation)

8x = 4

(divide both sides by 8)

x = 4/8

x = 1/2 or 0.5

Paulo’s grandfather gave him a collection of 20 coins. Each month Paulo adds 4 coins to his collection. Which inequality can be

Phoenix [80]

Answer:

$4m+20>50$

Step-by-step explanation:

Let m represent the amount of months that has passed.

Paulo started out with 20 coins.

Each month, he adds four more coins to his collection.

Therefore, the amount of coins added after m months will be given by 4m.

So, the amount of coins Paulo has total after m months can be given by:

$4m+20$

We want to know when Paulo will have "more than" 50 coins in his collection. Therefore, we will use the "greater than" sign. Thus, our inequality will be:

$4m+20>50$
