Johnny must learn more than 10 New Pl. Before the big game you're already learned for writing and recording that represents how
Ghella [55]

Question is Incomplete; Complete question is given below;

Johnny must learn more than 10 new plays before the big game. He has already learned 4. Write and solve the inequality that represents how many more plays he needs to learn to reach his goal?

Answer:

The Inequality representing the more plays he needs to learn to reach his goal is x+4>10.

Johnny should learn more than 6 games to reach his goals.

Step-by-step explanation:

Given:

Number of plays to be learn > 10

Number of plays already learned = 4

we need to write an inequality that represents how many more plays he needs to learn to reach his goal.

Solution:

Let the number of plays needed to learn more be 'x'.

So we can say that;

Number of plays already learned plus number of plays needed to learn more should be greater than total Number of plays to be learn.

framing in equation form we get;

x+4>10

Hence the Inequality representing the more plays he needs to learn to reach his goal is x+4>10.

On solving the equality we get;

Subtracting both side by 4 we get;

x+4-4>10-4\\\\x>6

Hence Johnny should learn more than 6 games to reach his goals.
