Answer:

40% discount

Step-by-step explanation:

To find this remember the formula [tex]\frac{discount amount}{original price} = \frac{percent discount}{100}[/tex]

To find the discount amount subtract $36 from $60 which is $24.

[tex]\frac{24}{60} = \frac{x}{100}[/tex] next you have to cross multiply

24*100 = 2400 and 60*x = 60x

Now you have the equation 2400 = 60x

Divide both sides by 60 to isolate the variable

x = 40

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:

A. 1.4*20 quarters

B.14

Step-by-step explanation:

A: 1.you start with 20 quarters= 20*1

2.you find 40% of twenty quarters in your room= 4/100*20=0.4*20

3.20*1+20*0.4= 20*1.4

B:20*1.4=28

28*50/100=14

Step-by-step explanation:

Answer: Since the circle is open, the symbol must be < or="">, because the boundary point is not included. The arrow points left, so the solution set includes all values less than the boundary point. I would use < in="" my="">

Step-by-step explanation:

Sample Response

The information that should be selected for symboling the equality function since the boundary point is not involved.

It is the relation type where it can graph and show any kind of relationship. rather drawing the lines for linking the dots here we have to shade the large areas for the graph.

Also, there is open circle so here the symbol should be like  < or=""> since  the boundary point is not involved. Also, the point of arrow should be in left hand side, so it should be lower than the boundary point.

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.

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:

bro

Step-by-step explanation:

bro i have no idea

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:

4

Step-by-step explanation:

10+-6 is the same as 10-6.

You can see this because there is a addition and subtraction symbol in the middle. You can use the KCC (keep, change, change) method to change the symbols from 10+-6 to 10-6. (You keep the 10, change the subtraction and addition symbols).

Answer: its 4

Step-by-step explanation: Because if you put it on a number line from 0 to 10. go right 10 times. then for -6 you go back left 6 times. and get 4. or just 10 - 6 = 4

[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]
