Answer:

C.

Step-by-step explanation:

5/4x-2=3/2x-4

5/4x-3/2x = -4+2

(multiply both sides by 4)

5x-6x=-16+8

-x=-8

(multiply by -1)

x=8

Answer:

C

Step-by-step explanation:

[tex]\frac{5x}{2} +\frac{7}{2} =\frac{3x}{4} +14\[/tex] isolate the terms with the variable x

[tex]\frac{5x}{2} -\frac{3x}{4} =14-\frac{7}{2}[/tex] get the same denominator and combine like terms

[tex]\frac{10x-3x}{4} = \frac{28-7}{2}[/tex] solve

[tex]\frac{7x}{4} =\frac{21}{2}[/tex] crossmultiply and solve for x

[tex]x=\frac{4*21}{7*2} =6[/tex] so is not the first option

try second

[tex]\frac{5x}{4} -9=\frac{3x}{2} -12[/tex] same steps as before

[tex]\frac{5x-6x}{4}=9-12\[/tex]

[tex]\frac{-x}{4} =\frac{-3}{1}[/tex]  so  x=12 not the second option

try third option

[tex]\frac{5x}{4} -2=\frac{3x}{2} -4[/tex]

[tex]\frac{5x-6x}{4} =2-4[/tex]

[tex]\frac{-x}{4} =\frac{-2}{1}[/tex] so x=8

Answer:

y = 3

Step-by-step explanation:

Given that,

TW = VW = 23,

TU = y + 24,

UV = 9y

∆TWU and ∆VWU are congruent by SAS Congruence Theorem.

Therefore:

TU = UV

y + 24 = 9y (substitution)

Subtract y from each side

24 = 9y - y

24 = 8y

Divide both sides by 8

24/8 = 8y/8

3 = y

y = 3

Answer:

A. 100 degrees

Step-by-step explanation:

Given:

[tex] m\angle ABC = 3y + 5 [/tex]

[tex] m\angle ADC = 5y - 45 [/tex]

Required:

[tex] m\angle BCD [/tex]

SOLUTION:

✍️First, create an equation that you will use to find the value of y.

[tex] m\angle ABC = m\angle ADC [/tex] (opposite angles of a parallelogram are congruent to each other)

[tex] 3y + 5 = 5y - 45 [/tex] (substitution)

Collect like terms

[tex] 3y - 5y = -5 - 45 [/tex]

[tex] -2y = -50 [/tex]

Divide both sides by -2

[tex] y = 25 [/tex]

✍️Next, find [tex] m\angle ABC [/tex] and [tex] m\angle ADC [/tex].

[tex] m\angle ABC = 3y + 5 [/tex]

Plug in the value of y

[tex] m\angle ABC = 3(25) + 5 = 75 + 5 = 80 [/tex]

[tex] m\angle ADC = 5y - 45 [/tex]

Plug in the value of y

[tex] m\angle ADC = 5(25) - 45 = 125 - 45 = 80 [/tex]

✍️Next, find [tex] m\angle BCD [/tex].

[tex] m\angle BCD + m\angle ADC = 180 [/tex] (consecutive angles in a parallelogram are supplementary)

[tex] m\angle BCD + 80 = 180 [/tex] (substitution)

Subtract 80 from each side

[tex] m\angle BCD = 180 - 80 [/tex]

✅[tex] m\angle BCD = 100 [/tex]

Answer:

20 inches by 28 inches

Step-by-step explanation:

The current size of the picture is 5 inches by 7 inches

If we want to enlarge the picture by a factor of 4, the perimeter will also increase by the factor of 4.

New dimension = 4(old dimensions)

= 4(5 inches by 7 inches)

= 20 inches by 28 inches

Hence, the size of the enlarged picture is 20 inches by 28 inches.

Answer:

7 %   $94.50(SALES TAX)   Question only asks for the SALES TAX THOUGH

Step-by-step explanation:

$1350.00 x .07 =$94.50

$94.50 is your sales tax on B

$1444.50 (total) x 15% gratuity  is $1444.50 x .15 = $216.68

$1444.50 + $216.68 =$1661.18  

$1661.18 x .02 =$33.22

$1661.18 + $33.22 = $1694.40 Total cost of your computer repair

Answer:

C.

Step-by-step explanation:

let the f(x) be x

2x-3/5=y

or,2x-3= 5y

or, x= 2y-3/5

inter changing the relation of x and y

x= 2y-3/5

:. f(x)= 2x-3/5

Step-by-step explanation:

2y-3/5 is the inverse of f(x)

Answer:

YES

Step-by-step explanation:

Find the equation of the line written as, y = kx. The graph shows a proportional relationship between y and x.

Constant of proportionality/unit rate/slope (k) = rise/run = ⁵/4.

Substitute ⁵/4 in y = kx

We would have:

y = ⁵/4x.

Using the equation of the line, we can know if a given point is on the line by plugging the value of x and y coordinates of the point into the equation. If it makes the equation true, then it is a point on the line. If it doesn't make the equation true, then it isn't a point on the line.

Let's plug in (16, 20) into y = ⁵/4x.

Thus substitute x = 16 and y = 20, we have:

[tex] 20 = \frac{5}{4}(16) [/trex]

[tex] 20 = (5)(4) [/trex]

[tex] 20 = 20 [/trex]

It makes the equation true. Therefore, the point, (16, 20) is a point on line l.

Answer:

[tex]\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}[/tex]

[tex]x=2,\:y=1[/tex]

Step-by-step explanation:

Given the equations

[tex]-5x-18y=-28[/tex]

[tex]-10x+9y=-11[/tex]

solving the system of the equation by elimination method

[tex]\begin{bmatrix}-5x-18y=-28\\ -10x+9y=-11\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}-5x-18y=-28\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:-10x-36y=-56[/tex]

[tex]\begin{bmatrix}-10x-36y=-56\\ -10x+9y=-11\end{bmatrix}[/tex]

[tex]-10x+9y=-11[/tex]

[tex]-[/tex]

[tex]\underline{-10x-36y=-56}[/tex]

[tex]45y=45[/tex]

[tex]\begin{bmatrix}-10x-36y=-56\\ 45y=45\end{bmatrix}[/tex]

solve 45y=5 for y:

[tex]45y=45[/tex]

[tex]\frac{45y}{45}=\frac{45}{45}[/tex]

[tex]y=1[/tex]

[tex]\mathrm{For\:}-10x-36y=-56\mathrm{\:plug\:in\:}y=1[/tex]

solve [tex]-10x-36\cdot \:1=-56[/tex] for x:

[tex]-10x-36\cdot \:1=-56[/tex]

[tex]-10x-36=-56[/tex]

Add 36 to both sides

[tex]-10x-36+36=-56+36[/tex]

[tex]-10x=-20[/tex]

[tex]\frac{-10x}{-10}=\frac{-20}{-10}[/tex]

[tex]x=2[/tex]
