Answer:
x for the first one is equal to-4
X=7 because 7-3 = 4, 7+8= 15,15x4=60.
2,6,18,54 because they have a common ratio of 3
Answer:
Area = 30
Step-by-step explanation:
Add the two sides
8 + 4 = 12
Multiply that number by the height
12 × 5 = 60
Divide that number by 2
60 ÷ 2 = 30
This is a ratio.
12 km : 3 h
simplify to-
4km : 1 h
which means the hiker traveled 4 km per 1 hour.
