If a statue that is 12 ft tall casts a shadow that is 15 ft long. find the length of the shadow that is 8 ft cardboard box casts

10 ft

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
