To solve number eight, you would set it up as an equation equal to 180
72+7x+24=180
Next you would combine like terms 24 and 72 to get 96
Now the equation is 96+7x=180 Now, subtract 96 from 180 and then divide by seven to get x, so then x is equal to 12
what do you need help with?
So 4*10^7 is _ times greater then 4*10^3
So, 4000, 40000000
So 10000 times greater
Actual length of the pole and the length of the shadow cast by the pole follow the proportional relationship.
Following this rule, 20 feet tall flagpole will cast 3.33 feet shadow.
If the length of the shadow = x feet
Proportional relationship will be defined by the expression,


feet
Therefore, length of the shadow cast by flagpole will be 3.33 feet.
