Answer:

Equilateral triangle is always a regular polygon

Step-by-step explanation:

We have to tell an equilateral triangle is a regular polygon.

Regular polygon is a polygon which has all angles and all sides are equal.

Equilateral triangle is a triangle with all three angles equal to 60° and all three sides equal.

Hence equilateral triangle is always a regular polygon

Answer:

<h3>Step-by-step explanation: for #2, look at 6 3/4 and make it into a decimal. Do the same to 7 1/2. Compare them both to see which one is shorter by subtracting 6 3/4 from 7 1/2 and when you get your answer for that, make that into a fraction. Predict that 6 3/4 is shorter because of how much less it is compared to 7 1/2. (I hope I helped you in some way. Good luck!)</h3>

(1 ÷ x- 1)+(2÷ x+2)=(3÷2) solve and check for extraneous solutions

Sliva [168]

$\frac{1}{x-1}+ \frac{2}{x+2}= \frac{3}{2}$
$\frac{1(x+2)}{(x-1)(x+2)}+ \frac{2(x-1)}{(x+2)(x-1)}= \frac{3(x-1)(x+2)}{2}$
$\frac{x+2+2(x-1)}{(x-1)(x+2)}= \frac{3(x-1)(x+2)}{2}$
$\frac{x+2+2x-1}{(x-1)(x+2)}= \frac{3(x-1)(x+2)}{2}$
$\frac{3x+1}{(x-1)(x+2)}= \frac{3(x^2+x-2)}{2}$
$\frac{}{(x-1)(x+2)}= \frac{3x^2+3x-6)}{2}$
$\frac{3x+1}{(x^2+x-2)}= \frac{3x^2+3x-6)}{2}$
$\frac{2(3x+1)}{2(x^2+x-2)}= \frac{3x^2+3x-6)(x^2+x-2)}{2(x^2+x-2)}$
$\frac{2(3x+1)}{2(x^2+x-2)}-\frac{3x^2+3x-6)(x^2+x-2)}{2(x^2+x-2)}=0$
$\frac{2(3x+1)-3x^2+3x-6}{2(x^2+x-2)}=0$

this will be continued

A carton of milk contains 1.89 liters. To the nearest whole number, how many 220-milliliter servings are in the container?

GuDViN [60]

Answer:

There are 8 220-mililiter servings in the container, with 130 mililiters left over.

Step-by-step explanation:

The mililiter unit of measure refers to 1/1000 liters. So 220 milliliters is actually 0.22 liters. Therefore, to determine the number of 220 milliliter servings that can fit in 1.89 liters, the following division must be performed:

1.89 / 0.22 = X

8.59 = X

Therefore, 8 servings of 220 milliliters (1,760 ml) could be served, with 130 milliliters left over.
