Answer:
243 ways
Step-by-step explanation:
Calculating the number of posible outcomes:
We have n trials.
Each trial has m possible outcomes.
The total number of outcomes is:

In this question:
5 questions, that is, 5 trials, so 
Each question has 3 options(True, false or unanswered). So 
How many ways?

area is found by multiplying length by width
so
26.4 times 12.25 =
and the answer is feet squared
Answer:
y = -6/5x +4
Step-by-step explanation:
6x+5y=20
Subtract 6x from each side
6x -6x+5y=20 -6x
5y = 20 -6x
Divide each side by 5
5y/5 = 20/5 -6x/5
y = 4 - 6/5x
We usually write the variable first
y = -6/5x +4
Answer:
x=4 y=8
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation
450 * 0.3 = 135 = money taken off the original price
