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
B,C,D are all equivalent.
I believe that the answer is A
Answer:
3/49
Step-by-step explanation:
The area of a rectangle is found using A = l*w. At the park, it measures A = 49*25 = 1,225 yards².
On the map the area is A = 3*25 = 75 inches².
The ratio of the area of the map to the area of the park is found by placing 75 ovre 1,225. Then simplify if possible.
