Answer:
8
Step-by-step explanation:
base x height / 2 = the area
4 x h / 2 = 16
h = 8
so x is 8
Answer:
Step-by-step explanation:
3*2x=6x, 3*5=10
So, 6x+10+4x = 5x+15
Add 6 and 4 which leaves you with 10x+10 = 5x+15
subtract 10 from 15 and that leaves you with 5 divided by 10x
x=2
Same for second equation
2*8x=16x and 2*3= 6
So 16x-6=16x+28
Add 6 to both sides so you get 34.
Now that 6 is gone you want x on one side so subtract 16x an it leaves you with 0. so X=34
The answer is C
Hope this helped
Solution
The table below is the required sample space of the to fair die
From the above table
The sample space contain 36 outcomes
Event A: The sum is greater than 9
we will look at the table and count all the elements that are greater than 9
There are 6 elements (they are 10, 10, 10, 11, 11, 12 from the table)
The probability for event A will be

P(A) = 1/6
Event B: The sum is an even number.
We will look at the table and count the number of elements that are even
There are 18 elements (notice that there are 3 even number on each of the 6 rows of the table)
The probability for event B will be

p(B) = 1/2
It would have to be X + 8
