$14 x 3= 42
$42 + $8=50
Answer: 2.2 miles.
Step-by-step explanation:
I guess that we want to find the distance between Lori's and Andrea's houses.
First, we have the locations:
L = (-3, 7)
A = (-3. -4)
To find the distance (in units) between two coordinate points (a1, a2) and (b1 b2) we can use the formula:
Distance = I (a1, a2) - (b1, b2)I = √( (a1 - b1)^2 + (a2 - b2)^2)
Then in this case we have that:
Distance = √( ( -3 -(-3))^2 + (7 - (-4))^2) = √( 0 + 11^2) = 11
The distance between their houses is 11 units.
And we know that each unit represents 0.2 miles, then 11 units represent 11 times that amount, the distance in miles will be:
D = 11*0.2 miles = 2.2 miles.
first make them into improper fractions 124/15 and 54/15 then subtract so it would be 70/15 then turn it into a mixed number 4 10/15
