Step-by-step explanation:
25+r = -5(2+8r)+6r
25+r= -10-40r+6r
25+r= -10-34r
34r +r = -25-10
35r= -35
r= -35/35
r= -1
Answer:
[tex]\huge\boxed{r=-1}[/tex]
Step-by-step explanation:
To solve for this equation, our goal is to isolate the variable r on one side by reversing the equation.
We have the equation [tex]25 + r = -5(2+8r)+6r[/tex]. Let's simplify it.
Apply the distributive property on the right:
[tex]25 + r = (-5 \cdot 2) + (84 \cdot -5) + 6r\\\\25+r = -10 - 40r + 6r[/tex]
Combine like terms:
[tex]25 + r = -10 - 34r[/tex]
Add 34r to both sides:
[tex]25 + r + 34r = -10 - 34r + 34r\\\\25 + 35r = -10[/tex]
Add 10 to both sides:
[tex]25 + 35r + 10 = -10 + 10\\\\35 + 35r = 0[/tex]
Subtract 35 from both sides:
[tex]35 + 35r - 35 = 0 - 35\\\\35r = -35[/tex]
Divide both sides by 35:
[tex]35r \div 35 = -35 \div 35\\\\r = -1[/tex]

Answer:
15.
[tex]x = 20[/tex]
16.
[tex]\angle BFH[/tex] = [tex]100\textdegree[/tex]
[tex]\angle CBD[/tex] = [tex]100\textdegree[/tex] (if needed)
-------------------------------------------------------------------
17.
[tex]x = 7[/tex]
18.
[tex]\angle BFH[/tex] = [tex]68\textdegree[/tex]
Step-by-step explanation:
15. The two following angles, which is [tex]\angle CBD[/tex] and [tex]\angle BFH[/tex], are Corresponding Angles. Write an expression by using the following measurements from [tex]\angle CBD[/tex] and [tex]\angle BFH[/tex]. Then, solve the expression for the value of [tex]x[/tex]:
[tex]\angle CBD[/tex] = [tex]5x[/tex]
[tex]\angle BFH[/tex] = [tex]3x + 40[/tex]
[tex]5x = 3x + 40[/tex]
Solve for [tex]x[/tex]:
[tex]5x = 3x + 40[/tex]
[tex]5x - 3x = 3x - 3x + 40[/tex]
[tex]2x = 40[/tex]
[tex]\frac{2x}{2} = \frac{40}{2}[/tex]
[tex]x = 20[/tex]
16. After you have the value [tex]x[/tex] use it to find the actual measurements of both [tex]\angle CBD[/tex] and [tex]\angle BFH[/tex], by applying [tex]x[/tex] to the following expressions from both [tex]\angle CBD[/tex] and [tex]\angle BFH[/tex] and solve them:
-The value of [tex]x[/tex]:
[tex]x = 20[/tex]
-Solve for [tex]\angle CBD[/tex]:
[tex]\angle CBD[/tex] = [tex]5x[/tex]
[tex]5(20)[/tex]
[tex]100[/tex]
-The actual measurement of [tex]\angle CBD[/tex]:
[tex]\angle CBD[/tex] = [tex]100\textdegree[/tex]
-Solve for [tex]\angle BFH[/tex]:
[tex]\angle BFH = 3x + 40[/tex]
[tex]3(20) + 40[/tex]
[tex]60 + 40[/tex]
[tex]100[/tex]
-The actual measurement of [tex]\angle BFH[/tex]: (if needed)
[tex]\angle BFH[/tex] = [tex]100\textdegree[/tex]
----------------------------------------------------------------------------
17. The two following angles, which is [tex]\angle BFE[/tex] and [tex]\angle DBF[/tex] are Alternate Interior Angles .Write an expression by using the following measurements from [tex]\angle BFE[/tex] and [tex]\angle DBF[/tex]. Then, solve the expression for the value of [tex]x[/tex]:
[tex]\angle BFE[/tex] = [tex]16x[/tex]
[tex]\angle DBF[/tex] = [tex]4x + 84[/tex]
[tex]16x = 4x + 84[/tex]
-Solve for [tex]x[/tex]:
[tex]16x = 4x + 84[/tex]
[tex]16x - 4x = 4x - 4x + 84[/tex]
[tex]12x = 84[/tex]
[tex]\frac{12x}{12} = \frac{84}{12}[/tex]
[tex]x = 7[/tex]
18. After you have the value [tex]x[/tex] use it to find the actual measurement of [tex]\angle DBF[/tex], by applying [tex]x[/tex] to the expression from [tex]\angle DBF[/tex] and solve it and find the actual measurement of an angle that is not labeled, which is [tex]\angle BFH[/tex]:
-The value of [tex]x[/tex]:
[tex]x = 7[/tex]
Solve for [tex]\angle DBF[/tex]:
[tex]\angle DBF[/tex] = [tex]4x + 84[/tex]
[tex]4(7) + 84[/tex]
[tex]28 + 84[/tex]
[tex]112[/tex]
-The actual measurement of [tex]\angle DBF[/tex]:
[tex]\angle DBF[/tex] = [tex]112\textdegree[/tex]
-Since both [tex]\angle DBF[/tex] and [tex]\angle BFH[/tex] are supplementary (two angles that equals to [tex]180\textdegree[/tex]), and you want to find the actual measurement of [tex]\angle BFH[/tex], Use the measurement of [tex]\angle DBF[/tex] and subtract it from [tex]180\textdegree[/tex]:
[tex]\angle DBF - 180\textdegree[/tex]
[tex]112\textdegree - 180\textdegree = 68\textdegree[/tex]
-The actual measurement of [tex]\angle BFH[/tex]:
[tex]\angle BFH[/tex] = [tex]68\textdegree[/tex]

A loss of yardage is generally considered to be a negative gain. That is the total gain in yardage for the two plays is
-3 + (-4) = -7= 7 total yards lost.
The total yards in these 2 plays is -17..
What is gain and loss?A gain is an increase in something whereas a loss is when something is decreased.
Since,A loss of yardage is generally considered to be a negative gain.
Now it is given that,
The first play of a game the eagles running back lost 3 yards.
Therefore, Lost in the first play of a game = -3
The next play the quarterback was sacked for afor a loss of 14 yards

Find the slope of the line that passes through the two points.
(12,-5) and (10,-4)
Given parameters:
First point = (12, -5)
Second point = (10, -4)
Unknown:
Slope of the line = ?
Slope is simply the vertical rise divided by the horizontal distance.
Slope = [tex]\frac{Rise }{horizontal distance}[/tex]
Simply to find slope;
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
First point = (12, -5), x₁ = 12 and y₁ = -5
Second point = (10, -4), x₂ = 10 and y₂ = -4
Input the parameters:
Slope = [tex]\frac{-4 -(-5)}{10 - 12}[/tex]
= [tex]\frac{-4 + 5}{-2}[/tex]
= - [tex]\frac{1}{2}[/tex]
The slope of the line is -[tex]\frac{1}{2}[/tex]

A man walks (12x^2+11x+2) km for (3x+2) hours. What is his speed per hour?
Step-by-step explanation:
Hey there!
Distance = 12x^2+11x+2.
And Time = 3x+2 hours.
Now;
[tex]speed = \frac{distance}{time} [/tex]
Put all values.
[tex]s = \frac{12 {x}^{2} + 11x + 2}{3x + 2} [/tex]
Use mid term factorization is numerator and simplify them to get answer.
[tex]s = \frac{12 {x}^{2} + (8 + 3) x+2 }{3x + 2} [/tex]
[tex]s = \frac{12 {x}^{2} + 8x + 3x + 2 }{3x + 2} [/tex]
[tex]s = \frac{4x(3x + 2) + 1(3x + 2)}{(3x + 2)} [/tex]
[tex]s = \frac{(4x + 1)(3x + 2)}{(3x + 2)} [/tex]
[tex]s = (4x + 1)[/tex]
Therefore the speed is (4x+1)/hr.

What is the equation of the line that has a slope of -4 and goes through (-1,6)?
Answer:
y = - 4x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 4, thus
y = - 4x + c ← is the partial equation
To find c substitute (- 1, 6) into the partial equation
6 = 4 + c ⇒ c = 6 - 4 = 2
y = - 4x + 2 ← equation of line

Answer:
Two collinear rays are parallel to each other.
Step-by-step explanation:
Two collinear rays parallel to each other, and they are on the same plane. Thus they do not meet even when extended till infinity.
An example of collinear rays is when you draw two parallel rays on a plain paper placed on an horizontal surface.
Your drawing should look like what is attached to this answer.
Yes, two collinear rays that do not intersect along with the figure attached at he end.
To draw two collinear rays that do not intersect, you can follow these steps:
1. Start by drawing a straight line segment. This will be the common line for the collinear rays.
2. Choose a point on one end of the line segment. This will be the starting point of the first ray.
3. Draw a line extending from the chosen point, in the same direction as the line segment, but do not let it intersect the line segment.
4. Choose another point on the other end of the line segment. This will be the starting point of the second ray.
5. Draw a line extending from the second point, also in the same direction as the line segment, but make sure it does not intersect the line segment or the first ray.

A bank manager makes $95,000 per year. If she is paid bi-monthly, what are her gross wages each paycheck
Answer:
gross wages each paycheck = $3,958.33 .
Step-by-step explanation:
Given that
she is paid bi-monthly.
it means that She is paid wages twice in the month.
Since there are 12 months in a year ,
she is paid = 12 month * twice in 1 month = 24 times in a year
___________________________________________
Given that she get $95,000 in a year
let here each bimonthly wage be x
thus, if she paid 24 times in a year
total wages [paid to her = 24* each bimonthly wage = 24x
24x should be equal to t $95,000
24x = $95000
x = $95000/24 = $3958.33
Thus, her gross wages each paycheck is $3,958.33 .
