Yolanda’s bowling average for 2 games was 138. Her second game score was 8 points lower than her first game score. Which system of equations will determine Yolanda’s scores for her first game, f, and her second game, s?

Answer:

║⊕║Hello Wonderful Person║⊕║

This should be your answer:

So first let us solve 138 divided by 2. Which equals 69. So right now, each game Yolanda did was 69 points. But, it says her second game score was 8 points lower. But it still has to be 138 points. So, you take away 8 points from S-69 (second game) and add 8 to F-69(First game) Which will equal 61 for S and 77 for F. So the answer is,

Yolanda's first game (F) was 77 points.

Yolanda's second game (S) was 61 points.

In total she scored 138 points.

Step-by-step explanation:

(brainliest appreciated!)

Yolanda’s scores for her first game, f is 73, and her second game, s is 65

Two or more expressions with an Equal sign is called as Equation.

Yolanda’s bowling average for 2 games was 138.

f+s=138....(1)

Her second game score was 8 points lower than her first game score.

s=f-8....(2)

Substitute 2 in 1.

f+f-8=138

2f-8=138

Add 8 on both sides

2f=138+8

2f=146

Divide both sides by 2

f=73

s=73-8

s=65

Hence, Yolanda’s scores for her first game, f is 73, and her second game, s is 65
