Input (x) while output (y)
Plug it into the equation
1. y = 2/2 + 1. Output = 2
2. y = 4/2 + 1 Output = 3
3. y = 7/2 + 1 output = 4.5
4. y = 9/2 + 1 Output = 5.5
2x + 8 = 16
2x = 16 - 8
2x = 8 (divide both sides by 2 to get x)
2x/2 = 8/2
x = 4
3x-26=10
3x=10+26
3x=36
X=12
Solve for x over the real numbers:
x^2 - 4 x - 5 = 0
The left hand side factors into a product with two terms:
(x - 5) (x + 1) = 0
Split into two equations:
x - 5 = 0 or x + 1 = 0
Add 5 to both sides:
x = 5 or x + 1 = 0
Subtract 1 from both sides:
Answer: x = 5 or x = -1
Answer:
33.3333333333
Step-by-step explanation:
we see that there are 6 candies in total
we also see that there is a 50% chance that someone will take out 3 candies of the same color,
50/3 = 16.66666666666667
so the chance of getting 2 marbles of the same color is 16.66666666666667 + 16.66666666666667 which is 33.3333333333
I hope I could help
Answer:
x = 16
Step-by-step explanation:
vertical angles are equal
3x = 2x+16
x = 16
