I'm only looking for an explanation, not the answer I want to find it myself. Please help a girl out! A tree is casting a shadow of 28 ft. At the same time, a 7ft statue was casting a shadow of 2ft. How tall is the tree? Remember, I don't want the answer just an explanation

Step-by-step explanation:

You have to find ratio for feet for a shadow.

In your case, a 7ft statue was casting a shadow of 2ft. You divide 7/2 and it results in 3.5 feet in real life vs. 1 foot shadow. You do the same for the tree. Since it is 3.5 feet:1 foot statue, you have to multiply 3.5 by 28 to get the full height of the tree. (In this example the shadow is smaller than the tree that's why you multiply).

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7
