the answer is a bc it just makes sense
Answer:
Step-by-step explanation:
Given that:
Batting average = 0.25 after 160 times at bat;
Batting Average = Number of hits / number of times at bat
0.25 = number of hits / 160
Number of hits = 0.25 * 160 = 40
He want batting average to improve to 0.333 ; if he makes hit the next x times at bat ; number of hits is needed to improve batting average
Hence,
New average = number of hits / number of times at bat
0.333 = (number of hits + x) / (160 + x)
0.333 = (40 + x) / (160 + x)
Answer:
x2 − 14x + 49 = 0

Answer:
1. 1
2. 5/8
3. 3/4
4. 7/8
5. 5/8
Step-by-step explanation:
1. The denominators are the same, so just add the top numbers (the numerator), 1/7 + 6/7 = 7/7, which is 1.
2. The denominators are the same, so just add the top numbers (the numerator), 7/16+3/16=10/16. 10/16 can be divided by 2 to get 5/8.
3. 1/6=2/12. So, the new problem is 2/12+7/12. Add the numbers, and you get 9/12. Divide the top and bottom by 3, and your answer is 3/4.
4. 3/4=6/8. The new problem is 6/8+1/8. This is 7/8.
5. 1/4=2/8. The new problem is 2/8+3/8. 2+3 is 5, so your answer is 5/8.
