The answer is A, 651. You would first start by multiplying the number of students, 1,860, by 45%, or .45. You'd come out with the answer of 837. You would then add 837 and 372 together to get a sum of 1,209. Finally, you would subtract 1,209 from the total number of students, which was 1,860 and get an answer of 651. I hope this helped you understand how a problem like this should be worked out!
Answer:
8 child tickets and 4 adult tickets.
Step-by-step explanation:
8c + 11a = 108
8x + 11y = 108
Lets graph it.
When we graph, we find that there it crosses at 2 whole numbers: (8, 4).
So there were 8 child tickets and 4 adult tickets.
We can check our work by doing 8(8) + 4(11) = 108
We find that this is true, so our answer is correct.
Answer:
-1.4f - 24
Step-by-step explanation:
First combine like terms
-2.3f + 0.9f - 15 - 9
-1.4f -24
So, simplified it is
-1.4f - 24
Answer: 30
Step-by-step explanation: To solve this problem, we're going to have to use the Pythagorean theorem...
a² + b² = c²
24² + 18² = c²
576 + 324 = c²
c² = 900
30
30 = c
I hope this helps!
8 times 4 and 8 times x
so 32 + 8x
