The area of the trapezoid is (1/2)(4+14)(10) = (5)(18) = 90.
The area of the triangle is (1/2)(14)(8) = 56.
Adding these, we get 56 + 90 = 146.

Whenever you have a decision tree like this, the probability of reaching a specific leaf is the multiplication of the probabilities of each step you have to reach the leaf.
So, in order to reach the "hardcover and nonfiction" leaf, we have to take the "buys hardcover" branch (probability 0.35), and then the "buys nonfiction" branch (probability 0.55).
Given what we said above, the probability for "hardcover and nonfiction" is
Answer:
a) 4(x - 2) = 100
4x - 8 = 100
4x = 92
x = 23
b) 2(x - 2) = 50
2x - 4 = 50
2x = 46
x = 23
Step-by-step explanation:
When solving for x in both equations, we get the same value of x which makes that statement true.
Answer:
The excluded value is x = 5/6
Step-by-step explanation:
Here, we want to calculate the excluded value
The excluded value is simply the value of x that will make the denominator of the fraction equals zero
We have this as;
6x -5 = 0
6x = 5
x = 5/6
Answer:
-28
Step-by-step explanation:
Let the number be x
Given that,
3( x+ 8) = 2x - 4
3x + 24 = 2x -4
3x-2x = -4-24
x= -28
