Answer:

145 + 33n

Step-by-step explanation:

Let

n = number of members in the club

Day 1:

Cost = 50 + 18n

Day 2:

Cost = 95 + 15n

Total cost two-day field trip = day 1 + day 2

= (50 + 18n) + (95 + 15n)

= 50 + 18n + 95 + 15n

= 145 + 33n

Total cost two-day field trip = 145 + 33n

An expression that represents the total cost in dollars for two days for the n members of the club is given by 145 + 33n

Answer:

  (1, 5)

Step-by-step explanation:

The midpoint of a line segment has coordinates that are the average of the end-point coordinates.

  M = (X + Y)/2 = ((-3, 4) +(5, 6))/2 = (-3+5, 4+6)/2 = (2, 10)/2

  M = (1, 5)

The midpoint is (1, 5).

How do i solve for this and find the missing one?
kompoz [17]

Answer:

your answer is 65 for the two missing angles

you take 50 and subtract it from 180 to get 130 then divide that by 2 you get 65

Step-by-step explanation:

or you can use the line which also equals 180 in all it has 115 on it so u would subtract 50 from it to get one of the angles then u would add 65 and 50 to get 115 and subtract 115 from 180 to get 65
