Answer:
Step-by-step explanation:
2x - 2 = x
Bringing like terms on one side
2x - x = 2
x = 2
Answer:
8/11
Step-by-step explanation:
Only 3 of the nickels are neither dimes nor Canadian. The other 8 of 11 coins are dimes or Canadian. The probability of choosing one of them at random is 8/11.
Answer:
a) distance = 0.5m
b) acceleration = -1.25m/s²
Step-by-step explanation:
v = d/t
d = vt
d = 10/20
= 0.5
a = v/t
= -10/8
= -1.25
a is negative because in the last 8s the care decelerate
Answer:
-2/2
Step-by-step explanation:
change in y is -2, change of x is 2
If we do it algebraically, we get
x + y = 420
This is the simplest equation. You see now this is a linear pair in two variables. Thus, there will be infinitely many solutions.
E.g - 419 + 1 = 420
42 * 10 = 420
21 * 20 = 420
etc,....
