Answers

Find the common denominator:

7/8+6/8
= 13/8 or $1 (5)/(8)$

On a coordinate map,a pizzeria is located at (9,3).A pizza is being delivered to a house located at (9,-3).Each unit represents 1 mile.How far is the pizzeria from the house?

Answers

Given two points (x₁,y₁) and (x₂,y₂) its distance will be:
distance=√[(x₂-x₁)²+(y₂-y₁)²]

In this case:
(9,3)
(9,-3)

distance=√[(9-9)²+(-3-3)²]=√36=6

Answer: The distance between the house and the pizzeria is 6 miles.
