Distance equals velocity times time.
d=vt
v=d/t
v=(3*2/5)km/5min
v=(6/5)/5
v=6/25 km/min
v=0.24 km/min
X=61 is your answer, hope this helps
Answer:
slope is 9
Step-by-step explanation:
use the formula y=mx+b wherein m is the slope and b is the y-intercept
to solve for m, use formula (y2-y1)/(x2-x1):
= 
(you add 5 and 9 together because negative + negative is positive)
126/14 = 9
(3c^2 − 5cd + d^2) − (7c^2 + 4cd − 9d^2) =
1. Drop the parentheses around the first polynomial since they are not needed.
= 3c^2 − 5cd + d^2 − (7c^2 + 4cd − 9d^2)
2. To drop the parentheses around the second polynomial, every sign inside changes.
= 3c^2 − 5cd + d^2 − 7c^2 - 4cd + 9d^2
3. Combine like terms. Like terms have the same variables and exponents.
= 3c^2 - 7c^2 - 5cd - 4cd + d^2 + 9d^2
= -4c^2 - 9cd + 10d^2
Answer:
a = 1/2
Step-by-step explanation:
a - 3/10 = 1/5
Add 3/10 to each side
a - 3/10 +3/10 = 1/5+3/10
a = 1/5+3/10
Get a common denominator
a= 1/5*2/2 +3/10
a = 2/10 +3/10
a = 5/10
Divide the top and bottom by 5
a = 1/2
