the number of girls and boys in math class totals 27. how many girls are there if the of girls is 3 more than twice the number boys?
Answers
Answer: 15 girls
Step-by-step explanation:
27 - 3 = 24
24/2 = 12
12 boys
12 + 3 = 15
15 girls
15+ 12 = 27
Answer: 15
Step-by-step explanation: Personally, I would try finding the number of boys first and then subtract the number of total students by the number of boys. To find the boys, you need to subtract three from 27 since those 3 are girls which leaves you with 24. It says there is half the number of boys than girls when you subtract 3 so 24 divided by 2 is 12. The number of boys is 12 so now all you have left to do is subtract 27-12 to find the number of girls, which is 15. I hope this helped you and sorry if it’s really long :)

Now you move the 4 onto the other side of the equal bars.
4-4-7x=18-4
Do the total.
-7x=14
Now you divide 14 by -7.
x=-2
There you have it.

Final answer:
The drivers in the race at Talladega Superspeedway cover a distance of approximately 803.63 kilometers in a 188-lap race.
Explanation:
The total distance covered in the race in miles can be computed by multiplying the length of a single track (2.66 miles) by the number of laps (188 laps). That gives 499.68 miles. This value is then converted to kilometers by using the fact that 1 mile is approximately equal to 1.60934 kilometers. Therefore the total distance in kilometers is computed as 499.68 miles * 1.60934 km/mile which is approximately 803.63 kilometers.
To convert miles to kilometers, we can use the conversion factor 1 mile = 1.60934 kilometers. Therefore, the total distance covered in one race at Talladega Superspeedway is 2.66 miles x 1.60934 kilometers/mile = 4.28 kilometers. Since the race is 188 laps long, we can multiply the distance covered in one lap by 188 to find the total distance covered in one race. So, the drivers cover a total of 4.28 kilometers/lap x 188 laps = 805.04 kilometers in one race.
