9) What 2 numbers have a total of 28 and a difference of 6?
Answer:
Sum: 17 + 11 = 28
Difference: 17 - 11 = 6
Step-by-step explanation:
The sum of x and y is 28. In other words, x plus y equals 28 and can be written as equation A:
x + y = 28
The difference between x and y is 6. In other words, x minus y equals 6 and can be written as equation B:
x - y = 6
Now solve equation B for x to get the revised equation B:
x - y = 6
x = 6 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 28
6 + y + y = 28
6 + 2y = 28
2y = 22
y = 11
Now we know y is 11. Which means that we can substitute y for 11 in equation A and solve for x:
x + y = 28
x + 11 = 28
X = 17
Summary: The sum of two numbers is 28 and their difference is 6. What are the two numbers? Answer: 17 and 11 as proven here:
Sum: 17 + 11 = 28
Difference: 17 - 11 = 6
Answer:
17 +11 = 28

Answer:
P = 3.6 + 6 + 3.6 + 6 = 19.2 units
Step-by-step explanation:
distance between (-3,-2) and (-5,-5) =
Sqrt[(-5-3)^2+(-5 - -2)^2]
Sqrt (4+9) = 3.6
d = (-5,-5) and (1,-5) =
Sqrt[(1 - - 5)^2 + (-5 - - 5)^2]
= sqrt (36 + 0) = 6
d = (1,5) and (3,-2)
Sqrt[(1 - - 3)^2 + (-5 - - 2)^2]
Sqrt(4+9) = 3.6
d = (3,-2) and (-3,-2)
Sqrt[(-3-3)^2 + (-2 - - 2)^2]
Sqrt (36+0) = 6

b) The total paid is the sum of the down payment and the monthly installments:
10815 = down + 1150×6
10815 -6900 = down . . . . . . . . . . subtract 1150×6 from both sides
down = 3915 . . . . . . . . . evaluate
The deposit paid was sh 3915.

What is a scatter plot?A Scatter Plot has points that show the relationship between two sets of data. The points are plotted on horizontal and vertical axes.
We have,
A positive linear association between two quantities variables.
Positive linear association means:
If one variable increases as the other variable increases.
Negative association means:
If one variable increases and the other variable decreases.
No association means:

whats 4(-2-9.2x)=3(2-7.6x) solve for x
Answer:
x = -1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
[tex](4)(-2) + (4)(-9.2x)=(3)(2)+(3)(-7.6x)[/tex] [tex]-8 - 36.8x = 6 - 22.8x[/tex] [tex]-36.8x - 8 = -22.8x + 6[/tex]Step 2: Add 22.8x to both sides.
[tex]-36.8x - 8 + 22.8x = -22.8x + 6 + 22.8x[/tex] [tex]-14x - 8 = 6[/tex]Step 3: Add 8 to both sides.
[tex]-14x - 8 + 8 = 6 + 8[/tex] [tex]-14x = 14[/tex]Step 4: Divide both sides by -14.
[tex]\frac{-14x}{-14}=\frac{14}{-14}[/tex] [tex]x = -1[/tex]Therefore, x = -1.
The solution to the equation 4( -2 - 9.2x ) = 3( 2 - 7.6x ) is x = -1.
What is the solution to the equation?Given the equation in the question:
4( -2 - 9.2x ) = 3( 2 - 7.6x )
To solve the equation 4(-2 - 9.2x) = 3(2 - 7.6x), distribute the constants and then isolate the variable x:
4( -2 - 9.2x ) = 3( 2 - 7.6x )
4 × -2 + 4 × -9.2x = 3( 2 - 7.6x )
-8 - 36.8x = 3( 2 - 7.6x )
-8 - 36.8x = 3 × 2 + 3 × -7.6x
-8 - 36.8x = 6 - 22.8x
Collect like terms:
-8 = 6 - 22.8x + 36.8x
-8 - 6 = - 22.8x + 36.8x
Add like terms:
-14 = 14x
14x = -14
Divide both sides by 14:
x = -14/14
x = -1
Therefore, the value of x is -1.

Given the graph of a proportional relationship, if the (2,7) lies on the graph, what is the value of k? What is the equation of the line?
Answer:
k=3.5, and y=3.5x is the equation of the line
Step-by-step explanation:
y and x are proportional means that y = kx for some constant k.
Thus, when y=7 and x=2, we have that 7 = k * 2, so that k = 7/2 = 3.5,
and the equation of the line is y = 3.5x
A raindrop fallsat a rate of 4/50mile in 1/20hour. At this rate, how far will the raindroptravelin 1 hour?(60 minutes)
Answer:
Step-by-step explanation:
1/20 hour = 5 minutes
(We can now call 1/20 of an hour 5 minutes)
If it falls 4/50 of a mile in 5 minutes (1/20 of an hour),
we do 4/50 * 12 because there are 12 5-minute intervals in an hour/
4/50 * 12 = 48/50 = 24/25 of a mile
Therefore, the raindrop will travel 24/25 of a mile in an hour.
The distance of the raindrop in an hour will be 24/25 miles.
What is speed?The speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is a scalar quantity and is described by its magnitude only.
Given that A raindrop falls at a rate of 4/50 mile in 1/20 hour. The distance in an hour will be calculated as:-
If it falls 4/50 of a mile in 5 minutes ( 1/20 of an hour ),
Distance = 4/50 x 12
Distance = 4/50 x 12
Distance = 48/50
Distance = 24/25 of a mile
Therefore, the distance of the raindrop in an hour will be 24/25 miles.
