First we subtract it:

18 - 15 = 3

Now we divide it to the original:

3 / 15 = 0.2

Multiply by 100:

0.2 * 100 = 20%

Answer:

20%

Step-by-step explanation:

percent of change = amount of change/original amount

First, subtract (to get the amount of change) 18 - 15 = 3

Plug numbers in according to the formula above 3/15

Simplify 1/5

1/5 x 100 = 100/5

Divide: 20

The answer is 20%

The midpoint of AB is (3,2). If point is is located at(8,4) what are the coordinates of point B

Dmitry [639]

Step-by-step explanation:

8-3 = 5,

3-5 = -2 = the x coordinate of B

-2-4 =-6,

-2-6 =-8 = the y coordinate of B

(-2,-8) is the point B

A is 5 to the right of the midpoint, so B is 5 to the left of the midpoint

A is 6 up from the midpoint so B is 6 down from the midpoint

Find the product of √3 and 5√3 in simplest form. Also, determine whether the

pshichka [43]

The product of √3 and 5√3 in its simplest form is 15.

<h3>What is a rational number?</h3>

A rational number is defined as a numerical representation of a part of a whole that represents a fraction number.

It can be a/b of two integers, a numerator a, and a non-zero denominator b.

To determine the product of √3 and 5√3

So, (√3 )(5√3)

⇒ 5 (√3 )(√3 )

⇒ 5(3)

⇒ 15

The result is rational because 15, can be expressed as a ratio of two integers can be 15/1 of two integers, a numerator 15, and denominator 1 ( which is a non-zero).

Thus, the result is rational.

Katherine bought snacks for her team's practice. She bought a bag of chips for $2.70 and a 12-pack of juice bottles. The total c

Naddika [18.5K]

1. A system of equations to determine the cost of a bottle of juice, is <u>12x + 2.70 = 15.78</u>.

2. From the equation, x = $1.09.

<h3>What is an equation?</h3>

An equation is a mathematical statement that shows that two values are equal.

A system of equations uses numbers and variables.

<h3>Data and Calculations:</h3>

The cost price of a bag of chips = $2.70

The total cost of snacks = $15.78

The total cost of 12-pack of juice bottles = $13.08 ($15.78 - $2.70)

Therefore, a bottle of juice = $1.09 ($13.08/12)

<h3>Equations:</h3>

Let a bottle of juice = x

Total cost of snacks = $15.78

2.70 + 12x = 15.78

or 12x + 2.70 = 15.78

12x = 13.08

x = 1.09 (13.08/12)
