Answer: 79%
Step-by-step explanation:
min —> 30 mins because half an hour is 30 mins.
(1 - 0.5)^30 = .214638..
1 - .214638 = .78536
round that to the closest percent equals 79%

so line ab is parrallel and so is xy it is asking you to prove that angle 8 + angle 9 = 180
so since they are parrallel 8 is equal to 12 or you could do 9 is equal to 5 then you can see that they sit on the same straight line so angle9 + angle8 = 180 degrees

Answer:
(13/24)
Step-by-step explanation:
let’s find a common number that we can get on the denominator
4 can be multiplied to get 48
6 can be multiplied to get 48
and 8 can also be multiplied to get 48
4(12) = 48
so for the equation (1/4) the numerator and denominator will both be multiplied by 12
(1/4)x(12/12) = (12/48)
6(8)= 48
(1/6)x(8/8) = (8/48)
8(6) = 48
(1/8)x(6/6) = (6/48)
now the fractions are
(12/48)+(8/48)+(6/48)
we can add them now because they have the same denominator and we get:
(26/48)
this can be simplified if we divide both the numerator and denominator by 2 and we get
(13/24)

Simultaneous equations can be solved by substitution, elimination, graphs and by matrices.
The values of x, y and z are:
[tex]\mathbf{x =3}[/tex].[tex]\mathbf{y = 6}[/tex].[tex]\mathbf{z = -1}[/tex]The equations are given as:
[tex]\mathbf{-x - y -z = -8}[/tex]
[tex]\mathbf{-4x + 4y +5z = 7}[/tex]
[tex]\mathbf{2x +2z = 4}[/tex]
Make z the subject in [tex]\mathbf{2x +2z = 4}[/tex]
[tex]\mathbf{2z = 4 - 2x}[/tex]
Divide by 2
[tex]\mathbf{z = 2 - x}[/tex]
Substitute [tex]\mathbf{z = 2 - x}[/tex] in [tex]\mathbf{-x - y -z = -8}[/tex]
[tex]\mathbf{-x - y -z = -8}[/tex]
[tex]\mathbf{-x - y - (2-x) = -8}[/tex]
[tex]\mathbf{-x - y - 2+x = -8}[/tex]
Cancel out common terms
[tex]\mathbf{- y - 2 = -8}[/tex]
Add 2 to both sides
[tex]\mathbf{- y = -8+2}[/tex]
[tex]\mathbf{- y = -6}[/tex]
Divide by -1
[tex]\mathbf{y = 6}[/tex]
Substitute [tex]\mathbf{z = 2 - x}\mathbf{\ and\ y = 6}[/tex] in [tex]\mathbf{-4x + 4y +5z = 7}[/tex]
[tex]\mathbf{-4x + 4 \times 6 + 5 \times (2 - x) = 7}[/tex]
[tex]\mathbf{-4x + 24 + 5 \times (2 - x) = 7}[/tex]
Open brackets
[tex]\mathbf{-4x + 24 + 10 - 5x = 7}[/tex]
Collect like terms
[tex]\mathbf{-4x - 5x =- 24 - 10 + 7}[/tex]
[tex]\mathbf{-9x =-27}[/tex]
Divide through by -9
[tex]\mathbf{x =3}[/tex]
Recall that: [tex]\mathbf{z = 2 - x}[/tex]
So, we have:
[tex]\mathbf{z = 2-3}[/tex]
[tex]\mathbf{z = -1}[/tex]
Hence, the results are:
[tex]\mathbf{x =3}[/tex]
[tex]\mathbf{y = 6}[/tex]
[tex]\mathbf{z = -1}[/tex]

solve for x 3(-x-3)+x-3=26
Answer:
[tex]\boxed {x = -19}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]3(-x - 3) + x - 3 = 26[/tex]
-Use Distributive Property:
[tex]3(-x - 3) + x - 3 = 26[/tex]
[tex]3(-x ) - 9 + x - 3 = 26[/tex]
-Combine both [tex]-9[/tex] and [tex]3[/tex]:
[tex]3(-x ) - 9 + x - 3 = 26[/tex]
[tex]3(-x ) - 12 + x = 26[/tex]
-Add [tex]12[/tex] to both sides:
[tex]3(-x ) - 12 + 12 + x = 26 + 12[/tex]
[tex]3(-x) + x = 38[/tex]
-Multiply the [tex]-1[/tex] by [tex]3[/tex]:
[tex]3(-x) + x = 38[/tex]
[tex]-3x + x = 38[/tex]
-Combine both the [tex]-3x[/tex] and [tex]x[/tex]:
[tex]-3x + x = 38[/tex]
[tex]-2x = 38[/tex]
-Divide both sides by [tex]-2[/tex]:
[tex]\frac{-2x}{-2} = \frac{38}{-2}[/tex]
[tex]\boxed {x = -19}[/tex]
Therefore, the value of [tex]x[/tex] is [tex]-19[/tex].
[tex]\bold{Hello!}\\\bold{Your~Answer~Is~Below!}[/tex]
______________________________
[tex]\bold{Solution~Steps:}[/tex]
When we have a problem with parenthesis we must use distributive property:
[tex]3[/tex] × [tex]-x-3[/tex]The [tex]3[/tex] cancels out, leaving [tex]-x[/tex]* [tex]3(-x)-9+x-3=26[/tex]
Subtract [tex]3[/tex] from [tex]-9[/tex]:
[tex]3-(-9)=-12[/tex]* [tex]3(-x)-12+x=26[/tex]
Add [tex]12[/tex] to both sides:
Since [tex]-12[/tex] is negative we do the opposite of what we see, so it cancels out. [tex]-12+12=[/tex] Cancels out[tex]26+12=38[/tex]* [tex]3(-x)+x=38[/tex]
Multiply [tex]3[/tex] and [tex]-1[/tex]:
In this case we have [tex]2[/tex] x's, so we need to get rid of one. We do this by turning [tex](-x)[/tex] into [tex]-1[/tex]. Then we multiply them together: [tex]3[/tex] × [tex]-1=-3[/tex]* [tex]-3x+x=38[/tex]
Combine like terms:
[tex]-3x+x=-2x[/tex]* [tex]-2x=38[/tex]
Divide to get [tex]x[/tex] alone:
Divide by [tex]-2[/tex] on each side by rule of opposites: [tex]-2x[/tex] ÷ [tex]-2=x[/tex] [tex]38[/tex] ÷ [tex]-2=-19[/tex][tex]\boxed{x=-19}[/tex]
