28 students travel on a field trip . They bring a van that can seat 12 students . Elena and Kiran's teacher asks other adults to

drive cars that seat 3 children each to transport the rest of the students . Elena wonders if she should use the inequality 12 + 3n > 28 or to figure out how many cars are needed . Kiran doesn't think it matters in this case . Do you agree with Kiran ? Explain 12 + 3n >= 28 your reasoning .
Need an answer please!! :(

Answer:

Yes, you can use this inequality to find the numbers of cars required.

Step-by-step explanation:

12  + 3n > 28     where n = the number of cars required

3n > 28 -12

3n > 16

n > 5 1/3

Greater than 5 1/3 gives 6 cars.

What’s the value of x for a-d?
patriot [66]

Answer:

a = 76 b = 22 c = 58 d = 68

Step-by-step explanation:

A. 180 - 133 = 47

so you have two angles found, which is 57 and 47. Add them together and subtract from 180. You get 76

B. 68 + 90 = 158

You subtract the 158 from 180 and get 22

C. This took some guess work, but when you multiply 58 by 2 you get 116. When subtracted from 180 you get 64. If you add 58 + 58 + 64, you get 180, so this made sense

D. There's an actual rule in trig that explains this, but I forgot it. If you look at the top angle, the other side of the line added to the 68 is a right angle. So you subtract 68 from 90 and get 12. Because there is already the right angle in the triangle, you just need the other two angles to equal 90, and because of the 68 that we found in the other triangle, this made sense.

Sorry, not the best at explanations. Hope that helped
