If Peter pays $84 to buy a watch after a discount of 30%, find the original price of the watch

Answers

(Original price) - 0.30p = 84

Let p = Original Price of the watch

p - 0.30p = 84

0.70p = 84

p = 84 ÷ 0.70

p = 120

The original price of the watch is $120.

Answer:

The original price was $120.

Step-by-step explanation:

Let the original price of the watch be w.

Then the discount is 0.30w and the discounted price is (1-0.30)w, or 0.70w.

Writing an equation in w, we get 0.70w = $84.

Solving this for w, we divide both sides by 0.70:

w = (84)/0.70 = $120

The original price was $120.

3. The bill at a restaurant
came to $136.40. The
patrons decided to leave a
15% tip. What was the total
bill including tip?

Answers

Answer:

$156.86

Step-by-step explanation:

$136.40 + 15% = $20.46

$136.40 + $20.46 = $156.86

You can also turn 15% into a decimal, so it would be 0.15
0.15 • 136.40 = 20.46
The Tip amount is 20.46
20.46+ 136.40 = (156.89)
(Total amount with Tip is 156.89)

Write the slope-intercept form of the equation of the line through the given points:

Answer:

equation of line

x-2y=8

Step-by-step explanation:

equation of line in slope intercept form

(y-y1)={(y2-y1)/(x2-x1)}(x-x1)

or,(y+3)={(-5+3)/(-2-2)}(x-2)

or,(y+3)=(1/2)(x-2)

or,2y+6=x-2

or,6+2 =x-2y

or,x-2y=8

Answer:

Step-by-step explanation:

(10j - 7) -(9j - 2) = x

(10j - 7) = x + (9j - 2)

10j - 7 = x + 9j - 2

10j - 9j -7 + 2 = x

Answers

Answer:The sum of three numbers is 112.

a+b+c=112

The second number is 5 times the first.

b=5a

so a+5a+c=112

6a+c=112

The third number is 20 less than the second. What is the second number?

c=5a-20

6a+5a-20=112

11a-20+20=112+20

11a/11=132/11

a=12

A recursive formula for the sequence 18, 9, 4.5, ... is

Answers

Answer:

Hope this image helps answer your question

and mark brainliest please.

The recursive formula is aₙ= aₙ₋₁ /2 for n > 1.

What is Recursive Formula?

A recursive formula is a formula used to describe a sequence of numbers, where each term in the sequence is defined in terms of the preceding term(s). In other words, it is a formula that uses one or more of the previous terms in the sequence to generate the next term.

The recursive formula for a sequence gives a way to find any term of the sequence using the previous term(s).

To find the recursive formula for the sequence 18, 9, 4.5, ..., we need to look at how each term is related to the previous term.

We can see that each term is half of the previous term, so the recursive formula is:

a₁ = 18 (the first term is given)

aₙ= aₙ₋₁ /2 for n > 1

This means that to find the nth term of the sequence, we divide the (n-1)th term by 2. For example:

a_2 = a_1/2 = 18/2 = 9

a_3 = a_2/2 = 9/2 = 4.5

a_4 = a_3/2 = 4.5/2 = 2.25

and so on.
