Spencer would be the correct one because it's easier to keep your variables positive when trying to solve. Therefore, in order to keep the variable positive, one would have to add 4x to both sides.
Volume = 2 x 6 x 1 + 1 x 2 x 2
Volume = 16 cubic feet
Shipping Cost = 20 + 1 x 6 = $26
Answer:
y = 3x
y = 18
Step-by-step explanation:
Let :
Distance walked by Jena = x
Distance walked by Karla = y
x = 6
y = 3x ;
y = 3(6)
y = 18 miles
5) k/35=3/7 : cross multiply
35*3=7k : simplify
105=7k : divide both sides of the equation by 7
k=15
6) 3/t=18/24 :cross multiply
18t=24*3 :simplify
18t=72 : divide both sides of the equation by 18
t=4
7) 10/8.4 = 5/m :cross multiply
10m=5 * 8.4 :simplify
10m=42 :divide both sides by 10
m=4.2
