What property was applied to solve the equation below? 0.36 x = negative 1.8
0.36 (divided by 0.36) x = negative 1.8 (divided by 0.36)
x = negative 5

Division property

Step-by-step explanation:

The property which states that we can divide both side of the equation by the same non-zero number is called the division property of equality.

The goal of dividing an equation is to isolate the unknown variable on one side.

For example, let the equation be:

2×x=10

Since the unknown variable x is being multiplied by the number 2, to isolate the variable an inverse operation needs to be applied - division:

2×x÷2=10÷2

Careful! Never forget to write the same operation on both sides of the equation! When doing so, the solution of the equation stays the same, i.e. we get an equivalent equation.

answer:

c. the third graph

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
