Can someone show me how to get the answer of -8 - 12 / (-4) step by step?
Answer:
-5
Step-by-step explanation:
12 ÷ -4 = -3Plug -3 in: -8 - -3Simplify: -8 + 3-8 + 3 = -53-x=5x+21
A: The solution set is (_) Simplified
B: There is no solution
Pick one and if A then simplify the answer
Answer:
[tex] \boxed{ \sf{ \bold{- 3}}}[/tex]Step-by-step explanation:
[tex] \sf{3 - x = 5x + 21}[/tex]
Move 5x to left hand side and change it's sign
⇒[tex] \sf{ - x - 5x + 3 = 21}[/tex]
Move 3 to right hand side and change it's sign
⇒[tex] \sf{ - x - 5x = 21 - 3}[/tex]
Collect like terms
⇒[tex] \sf{ - 6x = 21 - 3}[/tex]
Subtract 3 from 21
⇒[tex] \sf{ - 6x = 18}[/tex]
Divide both sides of the equation by -6
⇒[tex] \sf{ \frac{ - 6x}{ - 6} = \frac{18}{-6}} [/tex]
Calculate
⇒[tex] \sf{x = -3}[/tex]
Hope I helped!
Best regards!!
Answer:
x = - 3
Step-by-step explanation:
3 - x = 5x + 21
- x + 3 = 5x + 21
(- x + 3) + (- 3 - 5x) = (5x + 21) + (- 3 - 5x)
(- x + 3) + (- 5x - 3) = (5x + 21) + (- 5x - 3)
- x + 3 - 5x - 3 = 5x + 21 - 5x - 3
- x - 5x + 3 - 3 = 5x - 5x + 21 - 3
- 6x = 18
x = - 18/6
x = - 3

Step-by-step explanation:
BD is the altitude of the right ∆ which divides the hypotenuse to create two line segments, CD, and AD.
According to the right triangle altitude theorem,
[tex] BD = \sqrt{CD*AD} [/tex]
CD = 3, AD = 7, therefore,
[tex] BD = \sqrt{3*7} [/tex]
[tex] BD = \sqrt{21} [/tex]
Find x using Pythagorean theorem
[tex] x^2 = BD^2 + CD^2 [/tex]
[tex] x^2 = (\sqrt{21})^2 + 3^2 [/tex]
[tex] x^2 = 21 + 9 [/tex]
[tex] x^2 = 30 [/tex]
[tex] x = \sqrt{30} [/tex]

Which ordered pairs are in the relation {(x, y) | x > y 1} on the set {1, 2, 3, 4}?
Answer:
R = { ( 3 , 1 ) , (4 , 1) , (4 , 2) }
Step-by-step explanation:
Which ordered pairs are in the relation {(x, y) | x > y + 1} on the set {1, 2, 3, 4}
Assuming that:
R should be the set of real numbers such that:
R = { (x,y) | x > y + 1} on the set {1, 2, 3, 4}
Then:
The ordered pairs for the relation can be computed as:
R = { ( 3 , 1 ) , (4 , 1) , (4 , 2) }
A force of 150N is applied at an angle of 60° to the horizontal to pull a box through a distance of 50m. Calculate the work done
Answer:
Work done = 3750 Joules
Step-by-step explanation:
The force acting in the body should be resolved to it's horizontal component before we can use ut to solve for the problem
Horizontal component= 150 * cos 60
Horizontal component= 150*0.5
Horizontal component= 75N
Work done= Force * distance
Work done= 75*50
Work done= 3750 Nm
Work done = 3750 Joules

what is the rate of change of the linear function that has a graph that passes through the points (2, 9) and (-1, 3)
Answer:
Slope= 2
Step-by-step explanation:
Rate of change can simply be called slope
So the rate of change or slope of the linear function that passes through the points (2, 9) and (-1, 3) is
Slope = (y2-y1)/(x2-x1)
Where y2= 3
Y1= 9
X2= -1
X1= 2
Slope = (y2-y1)/(x2-x1)
Slope= (3-9)/(-1-2)
Slope= -6/-3
Slope= 2

Convert the following to slope-intercept form.
4x + 3y = 24
Answer:
y = -4/3x +8
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
4x+3y = 24
Subtract 4x from each side
3y = -4x+24
Divide each side by 3
y = -4/3x +24/3
y = -4/3x +8
Answer: y = -4/3x +8

Answer:
[tex][P(X_{1})\times P (X_{2})]>[\frac{9}{4}\times P (H_{1})][/tex]
Step-by-step explanation:
Let the candy "Honey Bunny" be labelled as H and the other candies as X.
It is provided that the machine is running out of "Honey Bunny".
So, Lisa wants to program it so that the probability of getting a candy other than "Honey Bunny" twice in a row is greater than 9/4 times the probability of getting "Honey Bunny" in one try.
Probability of getting a candy other than "Honey Bunny" twice in a row,P (X₁) × P (X₂)
Probability of getting "Honey Bunny" in one try,P (H₁)

Write a multiplication sentence to show how 10 gallons and 300 miles are related. How are 5 gallons ad 150 miles related? How are 1 gallon and 30 miles related?
Answer:
It shows for each gallon consumed, we multiply by 30 to get the amount of miles
This applies for the three questions
Step-by-step explanation:
10 gallons and 300 miles are related in such a way that you divide the number if miles by number of gallons.
300/10 = 30 miles per gallon.
It shows for each gallon consumed, we multiply by 30 to get the amount of Miles.
5 gallons ad 150 miles related in such a way that you divide the number if miles by number of gallons.
150/5 = 30 miles per gallon.
It shows for each gallon consumed, we multiply by 30 to get the amount of Miles.
1 gallon and 30 miles related in such a way that you divide the number if miles by number of gallons.
30/1= 30 miles per gallon.
It shows for each gallon consumed, we multiply by 30 to get the amount of Miles.

Ms. Ironperson and Mr. Thoro are making Avenger posters to give children when they visit Avenger Academy. Ms. Ironperson has completed 12 posters and will complete 6 more per day. Mr. Thoro has not started yet but can make 12 per day. At some point Mr. Thoro will catch up and both will have finished the same number of posters. When this does happen, how many posters will each Avenger have completed? If x denotes the number of days and y denotes the number of posters, what are the equations needed to solve this problem? Group of answer choices
Answer:
The equations needed to solve this problem are:
y = 12 + 6x
y = 12x
The number of posters completed by each Avenger will be 24.
Step-by-step explanation:
The information provided are:
Ms. Ironperson has completed 12 posters and will complete 6 more per day.
Mr. Thoro has not started yet but can make 12 per day.
The variable x denotes the number of days and y denotes the number of posters.
So, after x day the number of poster completed by Ms. Ironperson will be:
y = 12 + 6x
And after x day the number of poster completed by Mr. Thoro will be:
y = 12x
Thus, the equations needed to solve this problem are:
y = 12 + 6x
y = 12x
Compute the value of x as follows:
12x = 12 + 6x
6x = 12
x = 2
The number of posters completed by each Avenger is:
y = 12x = 12 × 2 = 24
Thus, the number of posters completed by each Avenger will be 24.

Kendrick is using a compass and straightedge to copy angle M. The figure shows the portion of the construction that he has already completed. Where should Kendrick place the center of the compass to do the next step of the construction?
Answer:
The question is not complete, but I found a similar question (image) that applies to this case:
The correct answer is:
Point N ( or where the arc cuts the horizontal line)
Step-by-step explanation:
From the figure attached to this answer, to copy angle in the first image on the left onto the inage in the right, Kendric first of all places tha centre of the compass at point M, and extends it to point N, to draw the first arc, which has already been done.
1. Next, the center of the compass should be placed at point N, and extended to the point where the arc touches the inclined line.
2. This measurement is then transferred to the new line, and the center of the compassed placed at point D, and a second arc drawn to cut the first arc.
3. Finally a line is drawn through the point where the two arcs meet to touch point C.
Consider the linear equation, 2.5n + 5.2 = 35.2.
What property will be used to complete the first step in solving for n?
Answer:
Subtraction Property of Equality
Step-by-step explanation:
When solving an equation for a variable (in this case n), we want to move all of the n-terms to 1 side and the non-n terms to the other side. To do this, we can subtract 5.2 from both sides to leave 2.5n by itself. The property we used to do this is the Subtraction Property of Equality which states that if you subtract a quantity from one side of an equation, you must also subtract that same quantity from the other side of the equation.
Answer: A is the right one
Step-by-step explanation:
Consider the linear equation, 2.5n + 5.2 = 35.2.
What property will be used to complete the first step in solving for n?
subtraction property of equality
multiplication property of equality
division property of equality
distributive property

Each of the sides of a square $S_1$ with area $16$ is bisected, and a smaller square $S_2$ is constructed using the bisection points as vertices. The same process is carried out on S_2 to construct an even smaller square $S_3$. What is the area of $S_3$?
Answer:
4 sq. units
Step-by-step explanation:
Because the vertices of S₂ are the midpoints of S₁, the area of S₂ will be half of that of S₁ which is 16 / 2 = 8. Similarly, because the same process is carried out on S₂ to make S₃, the area of S₃ is 8 / 2 = 4 sq. units.
