NEED HELP PLEASE !!!

Answer:

21.5 dollars

Step-by-step explanation:

Suppose the original price is x, then it became x+ x/100*20=1.2x

1.2x=25.8

x=21.5

Answer:

According to question, we get the following equation:

n-35% = 117

n-35/100 = 117

(100n-35)/100 = 117 ........... Took LCM

100n-35 = 117*100

100n-35 = 11700

100n = 11700-35

100n = 11665

n = 11665/100

n = 116.65 .......... ANSWER

Answer:

50,27

Step-by-step explanation:

let the parts be x and y

x+y=77

x=2y-4

substitute

2y-4+y=77

3y=77+4

3y=81

y=81/3=27

x=2×27-4=54-4=50

Answer:

n=-1

Step-by-step explanation:

Writing out the problem

8=-6n-2n

Simplifying "-6n-2n," which is -8n

8=-8n, or -8n=8

-8n=8

Divide both sides by -8

-8n/-8=8/-8

So, therefore, you get n=-1.

Answer:

write the expression for the perimeter of the 1st rectangle 6x

write the expression for the perimeter of the 2nd rectangle 4x + 30

write the equation 6x = 4x + 30

x= 15

perimeter = 90

Step-by-step explanation:

The perimeter is adding up all the sides of the rectangle.

So for the first one, we know two of the sides: x and 2x. The opposite sides have the same values. So the other two sides are x and 2x.

Therefore, the perimeter is

2x + x + 2x + x

or

6x

Similarly with the second rectangles:

(x+12) + (x+3) + (x+12) + (x+3)

Combine like terms

x + x + x + x + 12 + 3 + 12 + 3

4x + 30

Set these two equal to each other because the two perimeters are equal

6x = 4x + 30

Subtract 4x on both sides

2x = 30

Divide by 2 on both sides

x = 15

Check:

6(15) = 4(15) + 30

90 = 60 + 30

90 = 90

The common perimeter is

6*15 = 90 units

Answer:

$14.93

Step-by-step explanation:

she works 7+8=15 hours.

she earns in total per day

7×$23.46 + 8×$7.47 = $223.98

on average she makes per hour

223.98 / 15 = $14.93

She make on average 223.98 per hour for the day.

Given that,

She usually works at a retail store for 7 hours during the day and is paid $23.46 per hour by the store.

In the evening she works at a restaurant as a manager for 8 hours and is paid $7.47 per hour.

We have to determine,

How much does she make on average per hour for the day.

According to the question,

She usually works at a retail store for 7 hours earn = $23.46 per hour.

She works at a restaurant as a manager for 8 hours = $7.47 per hour

Total number of hours she works = 7hours + 8hours = 15hours

Therefore,

She make on average per hour for the day =

7×$23.46 + 8×$7.47 = $223.98

Hence, she make on average 223.98 per hour for the day.

Answer:

There are 2 hours and 15 minutes in 135 minutes

Step-by-step explanation:

We know that 1 hour = 60 minutes, 2 hours is 120 minutes, 3 hours is 180 minutes and so on. What amount of hours is 135 closest too? 2 hours.

Now that we know the amount of hours there is in 135 minutes, we need to find the rest of the minutes. To find this, we need to use subtraction. Subtracting [tex]120[/tex] from [tex]135[/tex] gives us [tex]15[/tex]. So, [tex]135[/tex] minutes is equal to 2 hours and 15 minutes.

Answer:

f(-5) = 19

Step-by-step explanation:

f(t) = -3t+4

Let f(t) = 19

19 =  -3t+4

Subtract 4 from each side

19 - 4 =-3t+4-4

15 = -3t

Divide each side by -3

15/-3 = -3t/-3

-5 = t

Answer:

the answer is -5

Step-by-step explanation:

F(t)=-3(t)+4

it told you that F(t) is equal to 19

so -3*-5=15+4=19

The perimeter of the figure is 4a.

The perimeter of a polygon is defined as the addition of the lengths of the polygon's each side.

The perimeter of a polygon = sum of all sides

To determine an expression for the perimeter of the figure as the sum of the lengths of its sides.

The perimeter of the figure as

The perimeter of  the figure = sum of all sides

⇒ 2(a-b) + a +2b +2c + a - 2c

Rearrange the likewise terms in the expression

⇒ 2a - 2b +2a + 2b

Apply the arithmetic operations in the expression

⇒ 4a

Thus, the perimeter of the figure is 4a.

Answer: See the diagram below

The table moves up and to the right

=========================================================

Explanation:

The lower right leg will move along that diagonal line shown on the right side.

Since the table is solid and not flexible, all of the other 3 points will move in the same pattern.

What results is what you see in the diagram below. The table moves to the right some distance and up some (other) distance along that diagonal path.

Note how the lower right leg is always on that path, since that path itself is the result of scraping that leg against the floor.

Also, I'm assuming your teacher wants purely a translation and nothing else. That means the table hasn't been rotated in any fashion.
