How do I solve this equation and check all the solutions?
Answers
Answer:
10
Step-by-step explanation:
x-√2x-5=5
-√2x-5=5-x
√2x-5=-5+x
2x-5=x²-10x+25
2x-5-x²+10x-25=0
12x-20-x²=0
-x²+12x-20=0
x²-12x+20=0
x=10
Note: there is a another answer x=2 but the equality will be false if x=2 so the answer is 10

Anelle is saving to buy a guitar that costs $350. So far she has saved $105.20. She wants to buy the guitar in 18 weeks. Based on this information, which statement is true?
Answers
Answer:
Step-by-step explanation:
350-105.20= 244.80 is still needed
I don't have the statements so...
244.80/18 weeks = 13.60 She'll need to save at least $13.60 a week for 18 weeks to make up the difference.
Answer:
Step-by-step explanation:
18x + 105.2 ≥ 350
18x ≥ 244.8
x ≥ 13.6
She has to save at least $13.6 per week.

Use the following table to determine P(X>4).
Answers
Answer:
0.11
Step-by-step explanation:
To get the probability above, we simply look for the events greater than 4, then add their probabilities
That is;
P(5) + P(6) + P(7)
So the probability in this case will be;
0.07 + 0.03 + 0.01 = 0.11

Type an (x,y) ordered pair that is a solution to this
equation.
Answers
Answer:
The ordered pair is (4,6)
Step-by-step explanation:
Ordered Pairs
It's given the equation
y = x + 2
Since there are no restrictions for the values of x and y, it has infinitely many solutions, i.e. any ordered pair of values (x,y) that make true the equation is a solution.
We can pick any value for x and then calculate the corresponding value for y as follows:
For x = 4,
y = 4 + 2 = 6
The ordered pair is (4,6)

Answer:
[tex]x=155[/tex]
Step-by-step explanation:
According to the definition of a linear pair:
[tex](x-25)+(50)=180[/tex]
Solve for [tex]x[/tex].
Combine like terms on the left:
[tex]x+25=180[/tex]
Subtract 25 from both sides:
[tex]x=155[/tex]
Hence, the value of [tex]x[/tex] is 155.
Answer:
x=155, the angle is 130 degrees
Step-by-step explanation:
Assuming you want to find x:
A straight line is 180 degrees so that means
x-25+50=180 add like terms together
x+25=180 subtract 25 from both sides
x=155
If you want to find the degree angle, just replace x with 155
x-25=155+25=130
Also if you want to know, yes I edited my answer as I couldn't tell if that was a + or a - in the picture. Have a nice day and happy thanksgiving!
How do I solve this equation and check the solutions?
Answers
Answer: x = -10 or 2
Step-by-step explanation:
Given:
√20 - 8x = x
Step 1: Square √20 - 8x
(√20 - 8x)² = (x)²
20 - 8x = x²
Now we can solve the problem
Step 2: Move 20 - 8x to the other side
20 - 8x = x²
-20 + 8x - 20 + 8x
0 = x² + 8x - 20
This is a quadratic equation
Step 3: Factor the quadratic equation
10(-2) = -20 and 10 - 2 = 8
So our factors are 10 and -2
(x + 10)(x - 2) = 0
Step 4: Create a FOIL equation
For this equation to be true, x would have to make either one of the parenthysis equal to zero
(x + 10)(x - 2)
x = -10 x = 2
10 - 10 equals zero, and -2 + 2 equals zero, so those are your answers.
