Question

To make the same totem pole with wood that costs y dollars Ronald would have to spend a total of $35.19. Explain which property of equality Ronald could use to solve the equation $10.50 + y = $35.19 and why that property can be used.

Answer 1

Answer:

Part 1) Subtraction Property of Equality

Part 2) This property can be used , because addition and subtraction have inverse relationships

Step-by-step explanation:

we know that

The subtraction property of equality tells us that if we subtract from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same

so

we have

$10.50+y=35.19$

Solve for y

Applying Subtraction Property of Equality

subtract 10.50 both sides

$10.50+y-10.50=35.19-10.50$

$y=\ 24.69$

Remember that this property can be used , because addition and subtraction have inverse relationships.
