Answer:
c = $1.4
p = $2.8
Step-by-step explanation:
two equations can be derived from the question
6p + 5c = 23.80 equation 1
7p + 6c = 28 equation 2
p = plates
c - cups
multiply equation 1 by 7 and equation 2 by 6
42p + 35c = 166.60 equation 3
42p + 36c = 168 equation 4
subtract equation 3 from 4
c = 1.4
substitute for c in equation 1
6p + 5(1.4) = 23.80
p = (23.80 - 7) / 6
p = 2.8
Answer:
6m
Step-by-step explanation:
9m - (5m-2) =

D = 5/6 sqrt(h)
7 = 5/6 sqrt(h)
42/5 = sqrt(h)
h = (42/5)^2 = 1,764/25 = 70.56
The height of the mast is 70.56 miles
