Complete Question

In the first half of a basketball game, a player scored 9 points on free throws and then scored a number of 2-point shots. In the second half, the player scored the same number of 3-point shots as the number of 2-point shots scored in the first half. Which expression represents the total number of points the player scored in the game?

a) 2x + 3x + 9

b) 2x + 3 + 9

c) 2x + 3x + 9x

d) 2 + 3x + 9

Answer:

a) 2x + 3x + 9

Step-by-step explanation:

Let the number of points shots a player scores = x

In a free throw, the player scored 9 points = 9

The player also scored a number of 2-point shots = 2x

In the second half, the player scored the same number of 3-point shots as the number of 2-point shots scored in the first half = 3x

The expression represents the total number of points the player scored in the game =

2x + 3x + 9

Answer:

X=75

Y=110

Step-by-step explanation:

A straight line is 180, so add the equations that make a line and set them equal to 180

x+20+x+10=180

Combine like terms

2x+30=180

Subtract 30 from both sides

2x=150

Divide by 2

X=75

Same for y

y+y-40=180

2y-40=180

Add 40 to both sides

2y=220

Divide by 2

Y=110
