Answer:

x=3-3/5y

Step-by-step explanation:

5x+3y=15

5x=15-3y

x=(15-3y)/5

x=3-3/5y

Answer:

x= 3 y=5

Step-by-step explanation:

solving for x

5x + 3y = 15 Zero out the substitute

5x +( 3y * 0) = 15

5x + 0 = 15 Adding by zero can be ommited

5x = 15 Divide both side by 5

x = 3

if solving for y

5x + 3y = 15

(5x*0) + 3y = 15 zero out the substitute

0 + 3y = 15

3y = 15 devide by the number in front of x

y= 5

Answer: D. base currency

Step-by-step explanation: In the foreign exchange market, currencies are traded in pairs.  A currency pair consists of two currencies, with one currency being quoted against the other.

In a currency pair, the base currency is the first currency listed.  It is the currency against which the exchange rate is quoted.  In the case of USD/CAN, USD is the base currency.  The base currency serves as a reference point for calculating exchange rates. It helps determine the value of the quote currency which  is the second currency listed in a currency pair.  It represents the value of the quote currency needed to purchase one unit of the base currency.  

Furthermore, changes in the exchange rate reflect the strength or weakness of the base currency relative to the quote currency.

The correct answer is Michelle makes a quarter turn to her right and Rebecca makes a three eight turn to her left.

Speed is the rate of change of position. It is the physical quantity that measures how quickly an object moves from one place to another. It is measured in units such as meters per second, kilometers per hour, or miles per hour. Speed is related to velocity, which is the measurement of how quickly an object moves in a specific direction. Speed is an important concept in physics and is necessary for understanding how the universe works.

Michelle makes a quarter turn to her right and Rebecca makes a three eight turn to her left. By making these turns, they will both end up facing north. A quarter turn to the right is the same as a three eight turn to the left. This is because a full turn is 360 degrees, so a quarter turn is 90 degrees and a three eight turn is also 90 degrees.

A: To find the intersection of the sets A and B, we need to find the elements that are common to both sets.

A = {x ∈ ℕ : 2 ≤ x < 19}

B = {x ∈ ℕ : x is even}

The intersection of the sets A and B is {x ∈ ℕ : 2 ≤ x < 19, x is even}

∩ = {4,6,8,10,12,14,16,18}

B: To find the difference of the sets A and B, we need to find the elements that are in set A but not in set B.

A = {x ∈ ℕ : 2 ≤ x < 19}

B = {x ∈ ℕ : x is even}

A. The interest amount will be $12.8.

B. He must pay Annual amount of $412.8 at the end of 6 months.

Interest is the idea that one party should be compensated for taking a risk and giving up the chance to use funds, while another party should be punished for using someone else's money.

The person who temporarily part with their money is entitled to compensation, and the person who temporarily uses those funds is frequently required to make this payment.

The simple interest is calculated as :

S.I = P×T×R

where,

S.I is the simple interest

P = Principal

T = Time period in years

R = Annual interest rate

The above problem,

Amount borrowed which would be the principal (P) = $400

Time period = 6 months = 1/2 year

Annual interest rate = 6.8% = 6.8/100 = 0.068

Substitute the details in formula

Simple Interest = 400×1/2×0.068

                         = 200 ×0.068

                         = 12.8

Amount to be paid = 400 + 12.8

                                = 412.8

Thus, the interest will be $12.8 and he must pay $412.8 at the end of 6 months.

Answer:

the equation for the ellipse that describes the arch is:

(x^2/20^2) + (y^2/6^2) = 1

Step-by-step explanation:

An ellipse can be represented by the equation (x^2/a^2) + (y^2/b^2) = 1, where a and b are the lengths of the semi-major and semi-minor axes of the ellipse, respectively. In this case, the x-axis coincides with the water level and the y-axis passes through the center of the arch, so the center of the ellipse is at the point (0, 6).

For the arch in question, the semi-major axis is 20 meters (since the arch spans a river 20 meters wide) and the semi-minor axis is 6 meters (since the center of the arch is 6 meters above the center of the river).

So the equation for the ellipse that describes the arch is:

(x^2/20^2) + (y^2/6^2) = 1

The monthly credit card payment would be $540.78, which is lower than the monthly payment on the bank loan.

What is simple interest?

Simple interest is based on the principal amount of a loan or the first deposit in a savings account. Simple interest doesn't compound, which means a creditor will only pay interest on the principal amount and a borrower would never have to pay more interest on the previously accumulated interest.

The simple interest earned can be calculated by using this formula

A = P(1 + rt)

Where,

A is the future value.

P is the principal value.

r is the interest rate.

t is the time.

Now Substituting the values into the formula, we have,

A = 16,000[1 + (0.08 × 3)]

A = 16,000[1 + 0.24]

A = 16,000× 1.24

Future value, A = $19,840.

Following that, we will compute the monthly payment over a 36-month period as follows:

Monthly payment = Future value/Time

Monthly payment = 19,840/36

Monthly payment = $551.11

Similarly, we will compute the credit card's compound interest:

A = 16000[1 + (0.15/12)]⁽¹² ˣ ⁷⁾

A = 16000[1 + 0.025]⁸⁴

A = 16000× 1.025⁸⁴

A = 9000 × 3.49258954

Future value, A = $45425.80

Following that, we will compute the monthly payment over an 84-month period as follows;

Monthly payment = Future value/Time

Monthly payment = 45425.80/84

Monthly payment = $540.78.

Hence, the monthly credit card payment would be $540.78, which is lower than the monthly payment on the bank loan.
