Answer:
d = 3 meters
Step-by-step explanation:
d = rt where d is the distance t is the time and r is the constant of proportionality
d = 18t
Changing 10 minutes to hours
10 minutes * 1 hours / 60 minute = 1/6 hour
d = 18 * 1/6 hour
d = 3 meters
Answer:
(4,4)
Step-by-step explanation:
y = 2x - 4 -------eqn 1
4y = x + 12 ------eqn 2
From eqn 1 y = 2x - 4; insert in eqn 2
4 (2x-4) = x + 12 (open the bracket)
8x - 16 = x + 12 (taking like figures to the same side, sign changes)
8x - x = 12 + 16
7x = 28
x = 28/7
x = 4
From eqn 1
y = 2x - 4
y = 2(4) - 4
y = 8 - 4
y = 4
(x,y) = (4,4)
