Answer:
8:14, 12:27, 40:70
Step-by-step explanation:
Answer:
A=12
B=54
C=18
Step-by-step explanation:
A=first
B=second
C=third
A+B+C=84
B=3C
A=C-6
C-6+3C+C=84
5C-6=84
5C=90
C=18
A=C-6
=(18)-6
=12
B=3C
=3(18)
=54
Answer:
graphing : Find the intersection points
substitution method : If you have e.g. x+2y=9 and x=3+2y, we can substitute it, (3+2y)+2y=9
elimination method : Make two variables the same, minus them and solve the equation
Step-by-step explanation:
Answer:
B. (x, y) --> (x, y + 5)
Step-by-step explanation:
Y is up and down
X is left and right
So assuming that Y is north she needs to go 5 units up Y
(x, y + 5) = (x, 5y)
