Distance cycled on Monday = p km
Distance cycled of Tuesday
= 8 km less than the distance cycled on Monday
= p km - 8 km
= (p - 8) km
So, distance cycled of Tuesday is (p - 8) km.
a sample that excludes subjects that are not part of the population being measured.
Answer:
X=3
A=4
B=5
Step-by-step explanation:
12a+15b+9c=
3*4*a+3*5*b+3*3*c=
3(4a+5b+3c) then
X=3
A=4
B=5
-2x + 15y = -24
2x + 9y = 24
Adding to eliminate x:-
24y = 0
y = 0
Substitute for y in the first equation:-
-2x + 15(0) = -24
-2x = -24
x = -24/-2 = 12
Solution is x = 12 , y = 0
It should open up because the a which is 4 is positive
