So, the question on my test was a pair of in line skates is on sale for 90. if this price represents a 9% discount from the original price, what is the original price to the nearest cent. My teacher got 98.90, but i got 98.10. which is mathematically correct?

Answer:

x = - 6

Step-by-step explanation:

A line with a slope of zero is a horizontal line parallel to the x- axis with equation

x = c ( where c is the value of the x- coordinates the line passes through )

The line passes through (- 6, - 7 ) with x- coordinate - 6 , then

x = - 6 ← equation of line

Answer:

y-1= -3/4(x-1)

Step-by-step explanation:

find the slope then put it in the format: y2-y1=m(x2-x1)

y-1= -3/4(x-1)

Answer:

y = -3/4x + 7/4

Step-by-step explanation:

So we have 2 points:

(-3, 4) & (1, 1)

The formula for point-slope is:

y - y1 = m (x - x1)

First, we need to find the slope between the points

The formula for this is

(y2 - y1) /(x2 - x1)

1 - 4 / 1 - (-3) ->

-3 / 4

Our slope is -3/4 (m)

y = -3/4 (x + 3) + 4

I've done this using a simplified formula for point slope which is

y = m(x - x1) + y1

we can simplify this equation more

y = -3/4x + 7/4

is our final equation.

Answer:

g(x)=3

Step-by-step explanation:

Answer:

26

Step-by-step explanation:

g(x) = 3x-1

f(x)= x+5

g(f(4)

plug 4 into f

f(4)

now apply x+5

f(4)=4+5=9

plug 9 into g

g(9)

now apply 3x-1

g(9)=3(9)-1

3 ×9= 27

27-1=26

hence the answer is 26

Answer:

135 onions

Step-by-step explanation:

bc

7 1/2 = 15/2

15/2 x 3 = 45/2

45/2 = 22.5

bc its only 1 of 6 pieces, you have to multiply 22.5 by 6

22.6 x 6 = 135

Answer:

Riley restoration rotators

Answer:

Step-by-step explanation:

first put 6:4

6 is 3 by 2

4 is 2 by 2

the 2 in 4 and 6 is gone

so we will have in the 6 3 left and in the 4 2 left

so what is 3 by 2

Answer: 9

Step-by-step explanation:

-3 1/3 x (-2 7/10)

-3  = -3*(3/3) = -9/3

-3 1/3 = -10/3

(-2 7/10)

-2  = -2(10/10) = -20/10

-2 7/10 = -27/10

(-10/3)*(-27/10) = (270/30) = 9

Answer:

3. W=4, L=10

4. W=4, L=8

Step-by-step explanation:

3.

L = 3W-2

W = W

P = 2L + 2W

P = 2(3W-2)+2W

P=28

2(3W-2)+2W=28

8W-4=28

8W=32

W=4

L=3W-2, or 10

Check: 2(4)+2(10) = 28? Yes

4.

L=2W

W=W

P=24

2L+2W=24

2(2W)+2W=24

6W=24

W=4

L=8

Check: 2(8)+2(4)=24 ? 16+8 = 24 Yes

Answer:

41 inches of wire will cost 164 cents.

Step-by-step explanation:

1st Method

Use proportions!

18/ 72 = 41/ c

Cross multiply

18 * c = 72 * 41

18c = 2952 divide both sides by 18

c = 164

2nd Method.

Find the rate of the costs. r = rate

18*r = 72

r = 4 cents/inch

Now that you've found the rate you can multiply it by 41 inches to find the cents the wire costs!

41 inch * r (cents/inch)          inches cancels out.

41 * 4 = 164

164 cents

Answer:

c and d are monomial because they have only one term

Answer:

the answer would be 11 hours and 25 minutes

Step-by-step explanation:

Answer:

4.42 hours

The reason why is by adding, 8:45 can round up to 9, and 1:10 can round down to 1, this make it simpler. 8:45+15 1:10-10

9AM to 1PM

9AM+3=12PM, add 1 and you get 1 pm=4 hrs, add 15+10, and you get somewhere close to it.

(I think you need a-e, if not let me know and I will edit accordingly)

a: Divide both sides by 4

cm -> 12:8

3:2

b: Convert and divide both sides by 3

cm -> 150:9

50:3

c: Convert and divide both sides by 20

cm -> 100:80

5:4

d: Convert and divide both sides by 4

months -> 4:12

1:3

e: Convert and divide both sides by 250

g -> 2000:250

8:1

Hope this helps, have a nice day :)

Answer:

x = 6

Step-by-step explanation:

110 and 19x - 4 are alternate exterior angles and are congruent, then

19x - 4 = 110 ( add 4 to both sides )

19x = 114 ( divide both sides by 19 )

x = 6

Answer:

There were 200 Questions on the Final.

Step-by-step explanation:

Answer:

$306

Step-by-step explanation:

Adult cost = no of adult × adult cost

no of adult = 12

adult tickets cost = $8

= 12 x $8

= $96

kids cost = no of kids x kids tickets cost

no of kids = 42

kids tickets cost = $5

= 42 x $5

= $210

total sales for the theatre =$96 +$210

= $306

Step-by-step explanation:

Answer:

15

The answer is 15 (if 3/5 is a fraction)

Queremos ver que fracción de la finca se ha destinado a plazas de aparcamiento.

La solución es:

La fracción de la finca que se destina a plaas de aparcamiento es 3/56

Sabemos que originalmente se iba a destinar 3/14 del total de la finca a plazas de aparcamiento, pero finalmente se destino 3/4 de lo previsto a zonas ajardinadas.

Es decir, se destino 3/4 de los 3/14 del total de la finca a zonas ajardinadas, entonces el 1/4 restante se dedico a plazas de aparcamiento, esto da:

(1/4)*3/14  = 3/56

La fracción de la finca que se destina a plaas de aparcamiento es 3/56
