Answer:

x = 7/12

Step-by-step explanation:

20 = 15(x + 3/4) (Given)

20 = 15x + 45/4 (Distribute)

35/4 = 15x (Subtract 45/4 on both sides)

7/12 = x (Divide 15 on both sides)

You can substitute the solution for x to check.

20 = 15(7/12 + 3/4)

20 = 15(4/3)

20 = 20

Mike saves $2,000 at a yearly simple interest rate of 2%. He earns $280 in interest. For how many years did he save this money?

Answers

Answer:

7 years.

Step-by-step explanation:

To find this, we need to find 2% of 2,000. To do this, we mulitply 2,000 by .02. This gets us 40. Now, we need to divide 280 by 40 to find the amount of years it took for Mike to get this money. When we do that, it gets us 7. That means Mike saved that money for 7 years.

The number of years that he saves this money will be 7 years.

What is simple interest?

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

The formula for interest is written as,

I = (PRT)/100

Where P is the principal, R is the rate of interest, and T is the time.

Mike saves $2,000 at a yearly simple interest rate of 2%. He earns $280 in interest. Then the number of years is calculated as,

$280 = ($2,000 x 2 x T) / 100

$28,000 = $4,000 x T

T = $28,000 / $4,000

T = 7 years

The number of years that he saves this money will be 7 years.

Find the length and width of a rectangle.
Perimeter = 50
Side A = 3x + 2
Side B = x - 5

Answers

Step-by-step explanation:

Perimeter = 2 * (Side A + Side B)

= 2 * (3x + 2 + x - 5)

= 2 * (4x - 3)

= 8x - 6.

We have 8x - 6 = 50, so 8x = 56 and x = 7.

Length of rectangle = 3(7) + 2 = 23.

Width of rectangle = (7) - 5 = 2.

Answer:

Length of rectangle = 3(7) + 2 = 23.

Width of rectangle = (7) - 5 = 2.

Find an ordered pair (x,y) that is a solution to the equation.
6x-y=1

Answers

Answer:
(1, 3 )
Step-by-step explanation:
To find a solution to the equation.
Rearrange making y the subject by subtracting 6x from both sides
Given
6x + y = 9, then
y = 9 - 6x
Substitute any value of x into the equation and solve for y to obtain a solution
x = 1 → y = 9 - 6(1) = 9 - 6 = 3
Thus (1, 3) is a solution to the equation

ordered pair (1, 5) is a solution to the equation 6x-y=1

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equation is 6x-y=1

We need to find an  ordered pair (x, y) that is a solution to the equation.

any values of x and y when we substitute in the given equation should give the result 1.

Those values are the solutions of equation

Let x=1 and y=5

6(1)-5=1

1=1

Hence, ordered pair (1, 5) is a solution to the equation 6x-y=1
