Answer: x = -7/2
Step-by-step explanation:
10x+ 30 = 20 +8x+ 3
10x+ 30=23+8x
10x-8x = 23-30
2x=-7

The answer is 9 because half of 14 is 7, and 7+2=9
Answer:
All options
Step-by-step explanation:
If two coins are flipped, there are following possibilities
1. Both coins show heads
2. First coin shows heads and second shows tails
3. First coin shows tails and second shows heads
4. Both coins show tails
Let H denote heads and T denote tails
Then the sample space can be translated from the above events as:
Sample Space for Flipping Two Coins = {HH, HT, TH, TT}
which means that all the options are correct ..
The permutation shows that when one has been cast yet, the different ways that are there to cast Fantine from the 28 women is 28.
<h3>How to calculate the value?</h3>
The different ways that are there to cast Fantine from the 28 women will be:
= 28!/(28 - 1)!
= 28!/27!
= 28
When Fantine has already been cast, the number of ways that are there to cast adult Cosette from the remaining women will be:
= 27!(27 - 1)!
= 27!/26!
= 26
When Fantine and adult Cosette have already been cast, the different ways that are there to cast Éponine from the remaining women is:
= (28 - 2)!/(28 - 2 - 1)!
= 26!/25!
= 25

Answer:
26.75
Step-by-step explanation:
There are two ways to do this. You can use the base*height/2 formula for the area of the triangle, or use the complex formula of determining triangle area without height.
The first is A=(b*h)/2
In this case you need to find the height using a²+b²=c²
Take your base (7.6) and divide it by 2 this will give you the bottom side of your triangle (3.8) now plug this, and the side value of 8 into the formula. Remember c is the hypotenuse (diagonal side) and x is the height.
3.8²+x²=8²
14.44+x²=64
x²=49.56
x=7.039 -now you have the height for the triangle and can use this to find the area
A=b*h (in this case we dont have to divide by two since we need two triangles because we split the original in two to find the base of 3.8)
so it's 3.8*7.039=26.75
(If you need more help look up Silicon Valley High school's video titled, "How to find the area of a triangle (without the height)"
It will teach you the formula 
which teaches you to find the area of any triangle when all you are given is three sides
