What is the correct answer?
Vedmedyk [2.9K]

Welcome to the era of LeBron. If you thought he was doing the game a disservice by being a sore loser and egomaniac, you haven’t seen anything yet. It wasn’t enough that he decided to become a pariah, he and his group of cronies have decided they want to ruin the NBA.

How? By systematically turning every superstar in the NBA into LeBron James. They are trying to turn them into spoiled, delusional, lying, quitting cowards.

Two of the biggest stories this offseason have been the drama in Denver and New Orleans. Both players, for whatever reasons, have decided that they no longer want to be the cornerstone of a franchise. Before the summer of Lebron, neither had really been asking to get out of their situations. So what is the common thread here? Well, both are represented by agent Leon Rose. Who else is represented by Rose? Why Mr. James, of course.

Answer:

ga = 14

gb = 17

Explanation:

It's just simply replacing the empty spaces (let's call those x) and doing the necessary operations. If I gave you T = 10 + x, T would be equal to 10x. Similarly, in the first problem we replace x with the given number g and then do all our operations (T = 10 + g(4)), in the second one, we also have to remember that the formula to calculate T is T = 10 + g. Knowing that, we replace the first blank (y) with 10, and the second blank with our given number g. I hope you do well :D
