Answer:

5(x + y) + 6(x − y)   =   11x − y

(5x − 3y) − x + 3x − 5y  =  7x − 8y

x − 4x + 6y + (14x − 5y)  =  11x + y

3x + 3y + 2(2x − y)  =  7x + y

whats the circumference in terms of pi?

Answers

Answer & Step-by-step explanation:

First, we must know the formula for finding the circumference of a circle.

Circumference = dπ

(d) represents your diameter. In order to find the diameter, you have to multiply the radius by 2 because the radius is half the size of the diameter.

The radius we are given is 15. So well do 15 multiplied by 2.

15 * 2 = 30

Now, since we have ti put the answer in terms of pi, then you are just going to leave 30 as it is and add the pi symbol.

C = 30π

solve for 7x2 = 10x

Answers

Answer:

x = 0, x = [tex]\frac{10}{7}[/tex]

Step-by-step explanation:

Given

7x² = 10x ( subtract 10x from both sides )

7x² - 10x = 0 ← factor out x from each term

x(7x - 10) = 0

Equate each factor to zero and solve for x

x = 0

7x - 10 = 0 ⇒ 7x = 10 ⇒ x = [tex]\frac{10}{7}[/tex]

Answer:

x = 1.4

Step-by-step explanation:

1. Simplify the left side so you get 14 = 10x

2. Divide the whole equation by 10

3. x = 1.4

If you had a nickel (.05 or five cents) that earned 100 percent interest each day or doubled in value each day. How much would you have after 10 days?

Answers

Answer:

Step-by-step explanation:

If the initial amount of nickel is doubling in value each day, it means that the amount of nickel is increasing in geometric progression. The formula for determining the nth term of a geometric sequence is expressed as

Tn = ar^(n - 1)

Where

n represents the common ratio

a represents the first term of the sequence (initial amount)

n represents number of terms in the sequence (days)

r represents common ratio between consecutive terms(days)

From the information given,

r = 2

n = 10

a = 0.05

Therefore, for 10days, T10

T10 = 0.05 × 2^(10 - 1)

T10 = 0.05 × 2^9

T10 = 25.6

Answer:

Having a nickel doubled for 10 days gives 512 nickels, or 2560 cents.

Step-by-step explanation:

Having a nickel doubled in value each day for 10 days, we first write the amount of nickels we have in the first few days, inspect what pattern these numbers take, write a general formula for the sequence formed, and use the formula to find the 10th number easily.

For the first five days we have:

Day1: 1

Day2: 1 + 1 = 2

Day 3: 2 + 2 = 4

Day 4: 4 + 4 = 8

Day 5: = 8 + 8 = 16

...

This is a geometric progression, where the first term is 1, and the common ratio is 2.

The nth term is given as

Tn = ar^(n - 1)

Tn = 1 × 2^(n - 1)

= 2^(n - 1)

That is

Day n = 2^(n - 1)

Day 10 = 2^(10 - 1) = 2^9 = 512 nickels.

But because 1 nickels = 5 cents

512 nickels = 5 × 512 = 2560 cents.
