Answer:
x = 7
Step-by-step explanation:
This is an isosceles triangle
This means two angles are identical
There are 2 angles with the size 9x-25
Now you should add all of the angles together
104 + 9x-25 +9x-25
Then simplify this
54 + 18x
You should know that angles in a triangle add up to 180
54 + 18x = 180
Subtract 54 from both sides
18x = 126
divide both sides by 18
x = 7

Since his score isgreater than one hundred thousand, that means that three of the balls landed in the section of 100,000 this will make the score 300,000.
If the other three balls, landed in the section of 10,000, this will make the score for the 3 balls to be 30,000
Therefore, his score will be 300,000 + 30,000 = 330,000

Answer: x=-2
Step-by-step explanation:
addition property of equality is adding the same number to both sides of an equation does not change the equation.
distributive property: a(b+c)=ab+ac
add 3 both sides of an equation.
6x-3+3=3x-9+3
simplify an equation
6x=3x-6
subtract 3x both sides of an equation
6x-3x=3x-6-3x
simplify
3x=-6
divide 3 both sides of an equation
3x/3=-6/3
simplify
-6/3=-2
the answer should be the negative sign.
x=-2
Hope this helps!
Thanks!

The numbers by writing and solving a system of equations are 50 and 105
System of equations
Let the unknown numbers be x and y
If twice a number plus twice a second number is 310, then;
2x + 2y = 310
x + y = 155
x = 155 - y
Also, If the difference of the numbers is 55, hence;
x - y = 55
155 - y - y = 55
155 - 2y = 55
-2y = 55 - 505
2y = 100
y = 50
Substitute y = 25 into 1 to have:
x = 155 - 50
x = 105
Hence the numbers by writing and solving a system of equations are 50 and 105

The difference between the numbers is 55.
Divide the first equation by 2 to get a 3rd equation:
Add the second and third equations together:
Put x=105 into the second equation to get:
So you're answers are x=105 and y=50.
