Answer:
The correct answer is x = 17.
Step-by-step explanation:
If EF bisects DEG, this means that angles DEF and angles FEG are congruent, and they each make up half of angle DEG.
Therefore, we can set up the equation:
DEF + FEG = DEG
However, since we know that DEF and FEG represent the same value, we can change this equation into the following:
2(DEF) = DEG
Now, we can substitute in the expressions that we are given:
2(3x+1) = 5x + 19
To simplify, we should first use the distributive property on the left side of the equation.
6x + 2 = 5x + 19
Our next step is to subtract 5x from both sides of the equation.
x + 2 = 19
Finally, we can subtract 2 from both sides of the equation to get x by itself on the left side.
x = 17
Therefore, the value of x is 17.
Hope this helps!

Step-by-step explanation:
The sales tax rate in Virginia is 4.5%. This is 2.5% less than the sales tax rate in Rhode Island. What is Rhode Island’s sales tax rate?
Answer:
7.0%
Step-by-step explanation:
If the sales tax in Virginia is 2.5% less than Rhode Island, then the tax rate in Rhode Island is 2.5% MORE than Virginia, so we add it to Virginia’s tax rate.
4.5% + 2.5% = 7.0%

Answer:
x= 5
Step-by-step explanation:
48 = 4x – 2 + 6x
Combine like terms
48 = 10x-2
Add 2 to each side
48+2 = 10x-2+2
50 = 10x
Divide by 10
50/10 = 10x/10

Move 2 to right hand side and change it's sign
[tex] \longrightarrow{ \sf{10x = 48 + 2}}[/tex]
Add the numbers: 48 and 2
[tex] \longrightarrow {\sf{10x = 50 }}[/tex]
Divide both sides by 10

Answer:
[tex]7x(x+2y-3yz)[/tex]
Step-by-step explanation:
First we find the greatest common factor of the coefficients, 7, 14 and 21.
The greatest common factor is 7.
Factor 7 out and divide the terms by 7:
[tex]7x^2+14xy-21xyz=7(x^2+2xy-3xyz)[/tex]
-----------------------------------------------------
Next, we find the greatest common factor of [tex]x^2,xy[/tex] and [tex]xyz[/tex].
The greatest common factor is x.
Factor x out and divide the terms by x:

The coordinates of the midpoint of line GH are M(−132,−6) and the coordinates of one endpoint are G(−4, 1). The coordinates of the other endpoint are
Answer:
Since, the coordinates of the midpoint of line GH are M(\frac{-13}{2}, -6)(

−13
,−6) .
The coordinates of endpoint G are (-4,1)
We have to determine the coordinates of endpoint H.
The midpoint of the line segment joining the points (x_1, y_1)(x
1
,y
1
) and (x_2, y_2)(x
2
,y

) is given by the formula (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})(
2
x

+x

y

+y

) .
Here, The endpoint G is (-4,1) So, x_1 = -4 , y_1=1x

=−4,y

=1
Let the endpoint H be (x_2,y_2)(x
2
,y

)
The midpoint coordinate M is (\frac{-13}{2}, -6)(

−13
,−6) .
So, \frac{-13}{2} = \frac{-4+x_2}{2}

{-13} = {-4+x_2}−13=−4+x

{-13}+4 = {x_2}−13+4=x

{x_2}=9x

Now, -6 = \frac{1+y_2}{2}−6=

-12 = {1+y_2}−12=1+y

y_2= -13y
