- 12x - 2(x + 9) = 5(x + 4) ← distribute parenthesis on both sides )
- 12x - 2x - 18 = 5x + 20 , that is
- 14x - 18 = 5x + 20 ( subtract 5x from both sides )
- 19x - 18 = 20 ( add 18 to both sides )
- 19x = 38 ( divide both sides by - 19 )
x = - 2 → A

Answer:
175
Step-by-step explanation:
find three consecutive odd integers with a sum of 75
Answer:
23, 25, 27
Step-by-step explanation:
first integer will be X, second will be (X+2), and the third will be (X+4). They will all be summed up and set equal to 75.
[tex](x) + (x + 2) + (x + 4) = 75[/tex]
combine like terms:
[tex]3x + 6 = 75[/tex]
subtract 6:
[tex]3x = 69[/tex]
divide by 3 to find value of X:
[tex] \frac{3x}{3} = \frac{69}{3} [/tex]
[tex]x = 23[/tex]
plug in X in o red der to finger the rest of the integers.
(X+2)= (23+2)=25
(X+4)= (23+4)=27

The product of a number and 7 decreased by 2
Answer:
(x× 7) -2
Step-by-step explanation:
(x× 7) -2
product of # = x
and 7 means to multiply
decreased by two means -2
Answer:
the product of a number and seven decreased by two is 7x-2
Step-by-step explanation:
a "product" is the answer to a multiplication problem. instead of writing a multiplication symbol (x) we can simply put the variable next to the number it is being multiplied to. (7x) so, a number (which can be written as any letter, since we don't know the exact number- it's a variable.) 7x decreased by 2 means subtracting. so, we get 7x-2.
hope this helps! best of luck <3
The definition of parallel lines requires the undefined terms line and plane, while the definition of perpendicular lines requires the undefined terms of line and point. What characteristics of these geometric figures create the different requirements?
Answer:
Parallel lines requires the terms line and plane because line and plane that are parallel cannot cross each other therefore they will never make a point of intersection. The characteristics of that parallel lines consists of lines and planes. Perpendicular lines requires the terms line and point because whenever two lines intersect, it creates a point and whenever two planes intersect, it creates a line. The characteristics of that perpendicular lines are points and lines.
The characteristics of the geometric figures that create the different requirements are;
Parallel lines are lines on the same plane and that are equidistant from each otherPerpendicular lines are lines that form a 90 degree angle at the point of their intersection.Reasons:
The characteristics of parallel lines are;
The shortest distance between the lines that are parallel is the same at all points along the lines.The lines are on the same plane.As the plane is extended indefinitely, the lines do not intersect.The characteristics of perpendicular lines are;
Perpendicular lines are lines that intersect at a point.Where two lines are perpendicular, the slope of one line is the negative reciprocal of the other, such that the product of the slopes of two lines that are perpendicular is -1.The angle formed at the intersection of perpendicular lines is 90°.An horizontal and a vertical line on the same plane are perpendicular to each other.Therefore, the characteristics of the geometric figures that create the different requirements are;
Parallel lines are lines on the same plane.Perpendicular lines are lines that form a 90 degree angle at the point of their intersection.Learn more about parallel and perpendicular lines here:

Step-by-step explanation:
A spinner with 8 equally sized slices has 2 yellow slices, 3 blue slices, and 3 red slices. The dial is spun and stops on a slice at random. What is the probability that the dial stops on a yellow or blue slice?
The probability that the dial stops on a yellow or blue slice will be 5/8.
What is mean by Probability?The term probability refers to the likelihood of an event occurring.
Given that;
A spinner with 8 equally sized slices.
It has 2 yellow slices, 3 blue slices, and 3 red slices.
Now,
Since, The dial is spun and stops on a slice at random.
Here, Number of yellow and blue slice = 2 + 3
= 5
And, Total number of slices = 8
So, The probability that the dial stops on a yellow or blue slice = 5 / 8

Latoya created a factor tree and wrote the prime factorization of 90 shown below. A factor tree of 90. 90 branches to 9 and 10. 9 branches to 3 and 3. 10 branches to 2 and 5. The equation is 90 = 2 times 3 times 5. What is Latoya's error? She should not have found the factors of 9. She should have included an exponent of 2 on the 3. She should have included 9 and 10 in the prime factorization. She should have started the tree with 2 times 45.

3x + 2y=11 // 2x - 2y = 14 solve I substitution method
Hey there! I'm happy to help!
To solve by substitution, rearrange one of the equations for one of the variables.
3x+2y=11
Subtract 2y from both sides.
3x=11-2y
Divide both sides by 3.
x=11/3-2/3y
Now we plug this value of x into the second equation to solve for y.
2(11/3-2/3y)-2y=14
We use distributive property to undo the parentheses.
22/3-4/3y-2y=14
We combine like terms.
22/3-10/3y=14
We subtract 22/3 from both sides.
-10/3y=20/3
Divide both sides by -10/3.
y=-2
We plug this value into one of the equations to solve for x.
3x+2(-2)=11
3x-4=11
Add 4 to both sides.
3x=15
Divide both sides by 3.
x=5
So, the solution is x=5 and y=-2 or (5,-2).

Step-by-step explanation:
3(x=4) = (3x+12) The (3x+12) is being multiplied by (x+7) and the 3 should only be distributed to (x+4) which meant the the equation when simplified should have become (3x=12)(x+7).

14F and by 10 PM, dropped 12. Plot points and draw arrows on the number
line below to model this situation.
What was the temperature at 10 PM? Explain how the number line helped you
find your answer.
Answer: - 1°F
Step-by-step explanation:
Given that:
At 8a.m:
Temperature = 3°F below 0
By 1p.m ; Temperature rose by 14F ;
By 10pm ; temperature dropped by 12F
Temperature at 10 pm:
3°F below 0 = - 3°F
Temperature at 1pm: temperature increased by 14°F
-3°F + 14°F = 11°F
Temperature at 10pm: temperature dropped by 12°F
11°F - 12 = - 1°F
