Solve for x :
-2x-5=4
Answers
Answer:
x= -9/2
Step-by-step explanation:
Add 5 to both sides:
-2 x -5 + 5 = 4 + 5
Simplify:
-2x = 9
Divide both sides by -2:
-2x/-2 = 9/-2
Simplify:
x= -9/2
Therefore the answer to the equation is x = -9/2. :)
The result to the equation-2 x- 5 = 4 is x = -4.5.
To break the equation-2 x- 5 = 4 for x, we will insulate the variable x by performing inverse operations.
Add 5 to both sides of the equation
- 2x- 5 5 = 4 5
- 2x = 9
Divide both sides of the equation by-2
- 2x)/-2 = 9/-2
x = -4.5
Thus, the result to the equation-2 x- 5 = 4 is x = -4.5.

Liz's age is two-thirds of Debbie's age. Debbie's age is half of Freya's age. what is the ratio of Liz's age to Freya's age?
Answers
Answer:
Let's start by using variables to represent the ages of the three people:
Let L be Liz's age.
Let D be Debbie's age.
Let F be Freya's age.
From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:
L = (2/3)D
We also know that Debbie's age is half of Freya's age, so we can write:
D = (1/2)F
To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:
F = 2D
Now we can substitute this expression for F into the equation for Liz's age:
L = (2/3)D = (2/3)(1/2)F = (1/3)F
So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.

Answers
Answer & Step-by-step explanation:
Using the clues given in the image, we can solve the logic problems as follows:
1. From clue 1, we know that Madison is either a programmer, a banker or a chemist.
2. From clue 2, we know that the programmer earns $44,700. Therefore, Alyssa and John cannot be the programmer.
3. From clue 3, we know that the banker earns more than the chemist. Therefore, Madison cannot be the chemist.
4. From clue 4, we know that Alyssa is either a programmer or a writer.
5. From clue 5, we know that the banker earns $53,600. Therefore, Madison is the banker.
6. From clue 6, we know that the chemist earns $42,200. Therefore, Christopher is the chemist.
7. From clue 7, we know that Madison earns more than the writer. Therefore, John cannot be the banker or the chemist.
8. From clue 8, we know that the programmer earns more than the chemist. Therefore, John is not the programmer.
9. From clue 9, we know that the writer does not earn $53,600. Therefore, Alyssa is the programmer and John is the writer.
10. From clue 10, we know that Christopher is either a programmer or a writer. However, we already know that Alyssa is the programmer, so Christopher must be the writer.
11. From clue 11, we know that John is not a banker or a programmer. Therefore, John is the writer.
12. From clue 12, we know that the writer earns more than the programmer. Therefore, John earns $48,100 and Alyssa earns $44,700.
Therefore:
- Madison is the banker and earns $53,600.
- Alyssa is the programmer and earns $44,700.
- Christopher is the writer and earns $53,600.
- John is the chemist and earns $48,100.
Answer:
The correct options are 3, 4, 5, 7, 9, 12, 13.
Step-by-step explanation:
3) The banker earns more than the chemist.
4) Alyssa is not a banker or a chemist.
5) The banker earns $53,600.
7) The banker earns more than the writer.
9) The writer does not earn $53,600.

two quadrilaterals that have matching angles but different side lengths.
Answers
Answer:
Step-by-step explanation:
ere are two quadrilaterals that have matching angles but different side lengths:
1.Quadrilateral ABCD:
Angle A = 90 degrees, Angle B = 60 degrees, Angle C = 120 degrees, Angle D = 90 degrees
Side AB = 5 units, Side BC = 10 units, Side CD = 5 units, Side DA = 10 units
2.Quadrilateral PQRS:
Angle P = 90 degrees, Angle Q = 60 degrees, Angle R = 120 degrees, Angle S = 90 degrees
Side PQ = 3 units, Side QR = 6 units, Side RS = 3 units, Side SP = 6 units
Both of these quadrilaterals have the same angle measures (90 degrees, 60 degrees, and 120 degrees) but different side lengths. Therefore, they are similar but not congruent.

Answers
Answer:
3/4
Step-by-step explanation:
Since (p, r) lies on the line y = x + b,
we have,
r = p + b -----eq(1)
Since (2p, 5r) lies on the line y = 2x + b,
we have,
5r = 2(2p) + b -----eq(2)
Sub the value of r from eq(1) in eq(2),
5(p + b) = 4p + b
⇒ 5p + 5b = 4p + b
⇒ 5b - b = 4p - 5p
⇒ 4b = -p
⇒ b = -p/4
sub in eq(1)
r = p + (-p/4)
= p - p/4
= 3p/4
⇒ r = 3p/4
⇒ r/p = 3/4
Answer:
3/4
Step-by-step explanation:
We have two lines:
r = p + b eq(1)
5r = 4p + b eq(2)
eq(2) - eq(1)
4r = 3p
dividing by 4p
r/p = 3/4

You are given a triangle with side lengths of 6, 9, and 12. Is the triangle a right triangle? How do you know?
Answers
Answer:
No, it's not
Step-by-step explanation:
You choose the longest side which is 12 and apply the theory of phitagors
The longest side which is the hypotenuse in a right triangle = square root the square sum for each side
So to be a right triangle it should be
\( \sqrt{ {9}^{2} + {6}^{2} } = 10.8 \: \: that \: doesnt \: equal \: 12\)
So it's not a right triangle.
Look at the famous right triangle whose side are 5(hypotenuse), 4, 3
\( \sqrt{ {4}^{2} + {3}^{2} } = 5\)
So it's a right triangle
Right triangle lengths can be checked by the Pythagorean theorem.
This states that a^2+b^2=c^2
a and b are the shorter side lengths, and they form the right angle. c is the hypotenuse, and is the longest length.
Input the values to check if the equation checks out:
6^2+9^2=12^2
36+81=144
117≠144
No, it is not a right triangle. Hope this helps!
