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.

if you are trying to figure out x-9=15 it’ll be 24

Answer: 24

Step-by-step explanation:

in in the previous activity you solved a system of equations representing the carnival admissions using the elimination method in this activity you will solve the same system using substitution then you'll compare your solution with the solution you obtained in the previous activity by using the elimination method

the two equations from the previous activity are given below

k + a = 500 (1)
3K + 10A equals 3,600 (2)

which equation has at least one of its variables with a 1 as it's coefficient?
​

Answers

Answer:

The value of a=300 and value of k=200

If you solve the above system of equations by elimination method, you will get the same values of a and k.

In Equation 1 [tex]k+a=500[/tex] both variables k has 1 as their coefficient.

Step-by-step explanation:

We need to solve the system of equations using substitution method

The equation are:

[tex]k + a = 500--eq(1)\\3k + 10a = 3,600 --eq(2)[/tex]

For substitution method, we find value of k from equation 1 and put in equation 2

[tex]From \ eq(1) \ we \ get\\k=500-a[/tex]

Putting it in eq(2)

[tex]3k+10a=3600\\Put \ k=500-a\\3(500-a)+10a=3600\\1500-3a+10a=3600\\7a=3600-1500\\7a=2100\\a=\frac{2100}{7}\\a=300[/tex]

So, we get value of a = 300

Now finding value of k by putting value of a in equation [tex]k=500-a[/tex]

[tex]k=500-a\\Putting \ a \ =500\\k=500-300\\k=200[/tex]

So, we get value of k =200

The value of a=300 and value of k=200

If you solve the above system of equations by elimination method, you will get the same values of a and k.

In Equation 1 [tex]k+a=500[/tex] both variables k has 1 as their coefficient.

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.

subtract 2 from both sides, -2-7=-9, j-9

Answer:

Step-by-step explanation:

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

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

10j - 7 = x + 9j - 2
