Answer:

$600

Step-by-step explanation:

$450 which is 75% of the original price

75%=3/4

$450=3/4op

$450/ 3/4 =op

$450*4/3=op

$450/3=150*4=$600

Answer:

it would be 8 because l l these symbols mean absolute value

which means positive so basically 12 minus 4

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

because if you take away the absolute value signs everything becomes positive.

Answer:

1/4

Step-by-step explanation:

5*3 is 15, 6*10 is 60, so it's 15/60, which when you simplify, is 1/4

A

Why? It starts at 0,0 and It's a straight line.

Answer:

[tex]x[/tex] = 12, [tex]y[/tex] = 10

Step-by-step explanation:

Given that:

Number of pennies = [tex]x[/tex]

Total amount in pennies = [tex]x[/tex] cents

Number of nickels = [tex]y[/tex]

Total amount in nickels = 5[tex]y[/tex] cents

Number of coins are not less than 20.

i.e. the inequality can be written as:

[tex]x+y>20 .... (1)[/tex]

Total money is not more than $0.75 i.e. 75 cents

The inequality can be written as:

[tex]x+5y<75[/tex] ...... (2)

Also, the number of nickels and pennies must be in positive numbers.

Therefore,  

[tex]x > 0 ...... (3)\\y > 0 ....... (4)[/tex]

When plotted in graph, we get the image as attached in the answer area.

Solution of the graph is the area which is common to both the lines.

And one solution between them is (12, 10)

i.e. number of pennies, [tex]x[/tex] = 12

Number of nickels, [tex]y[/tex] = 10

Answer:

See below

Step-by-step explanation:

DOK 3

[tex] In\: \triangle ABC, \:\\

m\angle A + m\angle B + m\angle C = 180\degree \\\\

m\angle A + 76\degree + m\angle C = 180\degree \\\\

m\angle A + m\angle C = 180\degree - 76\degree \\\\

m\angle A + m\angle C = 104\degree \\\\

\frac{1}{2} (m\angle A + m\angle C) =\frac{1}{2}\times 104\degree \\\\

\red{\bold{\frac{1}{2} (m\angle A + m\angle C) = 52\degree}}... (1)\\[/tex]

Since, AD and DC are bisectors of [tex] \angle A \: \&\: \angle C[/tex] respectively.

[tex] m\angle DAC= \frac{1}{2}m\angle A... (2)\\\\

m\angle DCA= \frac{1}{2}m\angle C...(3) \\[/tex]

Adding equations (2) & (3), we find:

[tex] m\angle DAC+m\angle DCA= \frac{1}{2}(m\angle A+m\angle C).... (4)\\[/tex]

From equations (1) & (4)

[tex] m\angle DAC+m\angle DCA= 52\degree... (5)\\\\

In \triangle ADC, \\

m\angle ADC + m\angle DAC +m\angle DCA = 180\degree... (6)\\\\[/tex]

From equations (5) & (6), we find:

[tex] m\angle ADC + 104\degree = 180\degree... (6)\\\\

m\angle ADC = 180\degree - 52\degree \\\\

\huge\purple {\boxed{m\angle ADC = 128\degree}}

[/tex]

DOK 4:

Let the measures of the angels 1, 2 and 3 be 4x, 5x and 6x respectively.

Therefore,

4x + 5x + 6x = 180°

15x = 180°

x = 180°/15

x = 12°

4x = 4*12° = 48°

5x = 5*12° = 60°

6x = 6*12° = 72°

[tex] m\angle 1 = 48\degree \\\\

m\angle 2 = 60\degree \\\\

m\angle 3 = 72\degree \\[/tex]

Step-by-step explanation:

I did the math and 17.95+27=44.95 and

                                 18.95+18=36.95

Answer:

Linear

Step-by-step explanation:

For instance your x value is 6. So you do 6*5, which equals 30, then -3 which gives you 27. Hope this helps.

Answer:

3/4

Step-by-step explanation:

Choose two coordinates on the line and use the slope formula to figure out the slope.

For example, use coordinates (0,-1) and (4,2).

Slope formula: y2-y1/x2-x1

2--1/4-0 = 3/4

Answer:

Perimeter ratio = 2:1

Area ratio = 4:1

Step-by-step explanation:

Perimeter

Perimeter of the smaller photo = [tex]2l+2w[/tex]

[tex]=2(5)+2(4)[/tex]

[tex]=18[/tex] inches

Perimeter of larger photo = [tex]2l+2w[/tex]

[tex]=2(10)+2(8)[/tex]

[tex]=36[/tex] inches

Ratio:

Perimeter of larger photo : perimeter of smaller photo = [tex]36:18[/tex]

[tex]=2:1[/tex]

Area

Area of smaller photo = [tex]lw[/tex]

[tex]=5\times4[/tex]

[tex]=20[/tex] inches²

Area of larger photo = [tex]lw[/tex]

[tex]= 10\times8[/tex]

[tex]=80[/tex] inches ²

Ratio

Area of larger photo : area of smaller photo = [tex]80:20[/tex]

[tex]=4:1[/tex]

∴The ratio of the perimeters = 2:1, and the ratio of the areas = 4:1

Hope this helps :)
