Answer:
im pretty sure it's D
Step-by-step explanation:
Answer : 3, 360 ways
Total number of people running the race = 16
We have three slot to be filled for first, second and third
Any person can take the first position irrespective of the arrangement
one out of the 16 people can come first
out of the 15 people remaining , one person can also come second remaining 14
out of the 14 people, one person can also come third
The number of ways the gift can be awarded = 16 x 15 x 14
The nummber of ways the prizes can be awarded = 3360 ways
5 consecutive even integers: n, n+2,n+4,n+6,n+8
n+(n+2)+(n+4)+(n+6)+(n+8)=1310
combine like terms
5n+20 = 1310
subtract 20 from each side
5n = 1290
divide by 5
n=258
n+2 = 260
n+4=262
n+6=264
n+8=266
Answer: 258,260,262,264,266
I think the answer for this is B
Placed them equal to each other.
3x + 6 = 4x - 2
6 (+2) = 4x (-3x)
8 = x
plug in x to both of the expressions
3(8) + 6 = 24 + 6 = 30
4(8) - 2 = 32 - 2 = 30
True
x = 8
hope this helps
B is wrong, because you do not set them equal to 180 ( you set them equal to each other). Next, it is wrong, because they messed up the end too.
hope this helps
