Let x = baby dinosaurs
y = adult dinosaurs
equation 1
total paintings = 15 painting x + 7 paintings y
equation 2
baby dinosaurs = 3 times adult
x= 3y
substitute x= 3y to equation 1
y = 4
x = 12
There are 12 baby dinosaurs and 4 adult dinosaurs in a herd with 208 total paintings
Answer:
19 5/8 miles
Step-by-step explanation:
First you convert all fractions into improper fraction which are
