Jack scored a mean of 15  points per game in his first 3  basketball games. in his 4th  game, he scored 27  points. what is his mean score for the first  4  games?

His mean score for the first 4 games will be 18 points.

Explanation

In the first 3 games, the mean of the scores is 15 points . Mean is the simple average of some numbers.

So, the total score in first 3 games = points

Now, in the 4th game, he scored 27 points. So, the total score in the first 4 games = points

Thus, the average of scores in first 4 games = points

So, his mean score for the first 4 games will be 18 points.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
