A group of church members chartered a bus for $832. After making the arrangements, 6 more members decided to join the excursion
g100num [7]
Let x = # of original members
Cost per person (originally) = 832/x
Cost per person after 6 more people = 832/(x+6)
Solve 832/x=832/(x+6) +6  (because the cost was reduced by 6 
Solve for x.
x = 26 or -32 (but x is number of members, so it can't be negative)
# of original members is 26.
Original cost is 832/26 = $32 per person.

Miguel plots points A, B, and C in the coordinate plane.
serg [7]

Answer:

part a: 5

part b: no, ABC is not an equilateral triangle

Step-by-step explanation:

part a: if you do the distance formula for points A and B, you get 5

part b: using the distance formula again, points A to B and points A to C are both 5, but points B to C is 6, therefore it's not equilateral because all the sides have to be the same length

I need help with this math problem!!
Vesnalui [34]
In order to find which one is or isn't, you need to solve for the value of 'x'. 
2x + 15 = 35 
2x = 20
x = 10 

Substitute x =10, into equation. If each side are not the same (i.e. 0=2), then that's the equation that is not equivalent,

Answer is B
Double check this. Chur! :)

Hope this makes sense.

The total number of ants is

(total number of sections)(ants in each section).

let x be the total number of ants.

Substitute the given values.

x = (9^2)(9^6)

x = 9^(2+6)  <= exponent rule: when multiplying exponents with the same base, add the exponents.

x = 9^8
