In a two digit number, the tens digit is 2 less than the units digit multiplied by 3. The reversed number is half of the original number plus 1/2. What is the original number?

Answers

Answer:

73

Step-by-step explanation:

Original number: XY

x = 3y - 2

10y + x = (10x + y) / 2 + 1/2

substitution: 10y + 3y - 2 = 13y - 2 = (10 * (3y - 2) + y) / 2 + 1/2

* 2 both sides and simplify: 26y - 4 = 31y - 19

31y - 26y = -4 + 19

5y = 15

y = 3

x = 7

The rate of sales tax on trousers is 10%. One can buy a pair of trousers at $ 660. What is the marked price?

Answers

Answer: $600

Step-by-step explanation:

The marked price is the price of the trouser without a sales tax.

The sales tax is 10% which means it increased the marked price by 10% to get to $660.

Assume that price is x:

660 = (1 + 10%) * x

x = 660/(1 + 10%)

x = $600

Answers

Find the other endpoint through middle point M. The formula for middle point M is the half of the sum of coordinates x,y. We have xm = 1/2 * ((-16) + x?) and by this pattern for y. The other endpoint has coordinates x = 16; y = -32;

Step-by-step explanation:

Here, we have three types of equations and three plotted graphs

we have a quadratic equation

an exponential equation

and a linear equation

For a quadratic equation, we usually have a parabola

The first equation is quadratic and as such the first graph that is parabolic belongs to it

For an exponential equation, we usually have a graph that rises or falls before becoming flattened

The second equation represents an exponential equation so the second graph is for it

Lastly, we have a linear equation

A linear equation usually has a straight line graph

Thus, as we can see, the third graph represents the linear equation

Samantha's college runs on a trimester schedule so she receives a bill 3 times a year for tuition. Each trimester costs 1,450 and Samantha must complete 2 years of college to receive degree. The average costs for books each trimester is 350$. Approximately what will be the total cost of Samantha to get her degree?

Answers

Answer:

$89100

Step-by-step explanation:

Given data

Each trimester costs=$1,450

time taken to complete degree= 2 years

In 1 years, she will pay = 14500*3=  $43500

In 1 years, she will pay =$43500*2=  $87000 in tuition

The average costs for books each trimester is 350$

In 1 years, she will pay =  350*3=  $1050

In 1 years, she will pay =$1050*2=  $2100 for books

In all she will pay

87000+2100=$89100

Answer: Zero slope.

Step-by-step explanation: The line does not increase or decrease, so your two options are undefined or zero. If the line were vertical (up and down), the slope would be undefined since there would be many y-values for one x-value. Since the line is horizontal (right to left), though, each x-value only has one y-value. Since the y-value doesn’t change, the slope is zero.
