Answer:
2.8
Step-by-step explanation:
10× X = 7× 4
X = 7×4/10 = 2.8
will she would have rode 4 3/5 miles in all.
2 3/10+2 3/10=4 3/5
that is 2 3/10 there and 2 3/10 back so you would add that together.
MILES IN ALL 4 3/5
Hope this helps
Answer:
10 units
Step-by-step explanation:
To find the length we can use the formula
d = sqrt( (y2-y1)^2 + (x2-x1)^2)
We have the two points (-5,5) and (3,-1)
d = sqrt( (-1-5)^2 + (3--5)^2)
d = sqrt( (-6)^2 + (3+5)^2)
d = sqrt( (-6)^2 + (8)^2)
d = sqrt( 36 + 64)
d = sqrt(100)
d = 10
