Their distance differs by 15 miles for each hour of travel time. Thus, the travel time of interest is
.. (180 -144) miles/(15 miles/hour) = 2.4 hour
The red car's speed is 180 mi/(2.4 h) = 75 mi/h.
The blue car's speed is 144 mi/(2.4 h) = 60 mi/h.
a, b and e
a.
x + 5 = 8 ( subtract 5 from both sides )
x = 3
b
4x = 12 ( divide both sides by 4 )
x = 3
c
= 3 ( multiply both sides by 9 )
x = 27
d
x - 5 = 10 ( add 5 to both sides )
x = 15
e
= 3
note that = x, hence
x = 3
Answer:
The puppy weighed 6 pounds at birth
Step-by-step explanation:
You go from 4 to 0...seeing as the weight is changing by 2.5..you subtract 2.5 by 16, 4 times in order to get the birth weight.
16 - 2.5= 13.5 - 2.5 = 11 - 2.5= 8.5 - 2.5 =6
Answer:
Step-by-step explanation:
area of a square is just L^2 or one of the sides squared
and the perimeter is 4L
that means
Area = 5.25^2
= 27.5625 in^2
Perimeter = 4 * 5.25
= 21 in
It’s just there to be there it means nothing hope it helps!
