<span>(12.67 + 19.2)(3.99) / (1.36 + 11.366) = 31.87(3.99) / 12.726 = 127.1613 / 12.726 = 9.992</span>
Answer:
C). 9
Step-by-step explanation:
Given: f(x) = 8(x - 4) - 18
If f(x) = 22;
8(x - 4) - 18 = 22
8x - 32 - 18 = 22
8x - 50 = 22
8x = 22 + 50 = 72
x = 72 ÷ 8 = 9
Step-by-step explanation:
So you add one over the other
3x-2y=7
-3x+5y=5
=
3y=12
Then you divide 3 from both sides
(3y)/3=12/3
y=4
Then you substitute the y=4 in to the equation of your choice
3x-2(4)=7
3x-8=7
3x-8=7
+8 +8
3x=15
x=5
Using the fundamental counting theorem, it is found that 17,576,000 different license plates can be manufactured.
Fundamental counting theorem:
States that if there are n things, each with ways to be done, each thing independent of the other, the number of ways they can be done is:
In this problem:
- Since repetition is allowed, for the 3 letters, there are 26 outcomes, hence .
- For the 3 numbers, there are 10 outcomes, hence
Then:
17,576,000 different license plates can be manufactured.
