Answer:
Aaron's bowling score is 30
David's bowling score is 54
Step-by-step explanation:
The variable representing Aaron's score is = a
The variable representing David's bowling score = d
The sum of their scores is 84.
= a + d = 84...... Equation 1
David's bowling score is 6 less than 2 times Aaron's score.
d = 2a - 6
Substituting 2a - 6 for d in Equation 1
a + 2a - 6 = 84
3a - 6 = 84
3a = 84 + 6
3a = 90
a = 90/3
a = 30
Hence, Aaron's bowling score is 30
d = 2a - 6
d = 2(30) - 6
d = 60 - 6
d = 54
David's bowling score is 54
Always start with what’s in the parentheses:)
Answer:
2) $25.01 3) $25.98
Step-by-step explanation:
2) 23.6 x 7% = 23.6 x .07 (move the decimal 2 places to the right) 23.6 x .07 = 1.652 but its money so round to $1.65 + 23.36 = $25.01
3) 24 x 8.25 = 24 x .0825 (again to the right twice) 24 x .0825 = 1.98+24 = 25.98
