Solve the following equation for x:<br><br> 12x+2=26

Maslowich

Answer:

$\large{ \tt{❃ \: STEP-BY-STEP \: EXPLANATION}} :$

$\large{ \tt{❁ \: ORIGINAL \: PROBLEM : 12x + 2 = 26}}$

We want to remove the 2 first. Since the original equation is + 2 , we're gonna use the opposite operation and subtract 2 form both sides.

$\large{ \tt{↦ \: 12x + 2 - 2 = 26 - 2}}$

Simplify! 2 - 2 = 0 on the left and 26 - 2 = 24 on the right.

$\large{ \tt{↦ \:12x = 24}}$

Then we need to think about how to remove the coefficient 12 . Since the opposite of multiplication is division , we're going to divide both sides by 12.

$\large{ \tt{ ↦ \: \frac{12x}{12} = \frac{24}{12}}}$

Simplify. 12/ 12 = 1 on the left and 24 / 12 = 2 on the right. So our answer is x = 2 .

$\boxed{ \boxed{ \large{ \tt{↦x = 2}}}} \large✓$

Find the distance between the two points.

Harrizon [31]

<h2>Answer</h2>

$2\sqrt{10}$

<h2>Explanation</h2>

1. Use Distance formula

Important to use distance formula in such problems, so keep this formula memorized for future use.

The formula to find distance amongst two points is

$\sqrt{(x^2-x^1)^2 + (y^2 - y1)^2}$

2. Plug in the numbers into the formula:

1 -(-1)^2 + 3 - (-3)^2

$2^2=4$

$6^2 = 36$

36 + 4 = 40

3. Find the square root of 40.

$\sqrt{40}$

Simplify further:

$2\sqrt{10}$

Quadrilateral ERGF is inscribed in a circle Find the measure of angle E (Remember to show formulas equations and numbers in thos

Kitty [74]

The measure of angle E is 75°.

Solution:

Given data:

∠E = 5x, ∠F = 7x – 13 and ∠R = –2 + 6x

A quadrilateral inscribed in a circle is called cyclic quadrilateral.

∠R and ∠G are opposite angles in a cyclic quadrilateral.

<em>In cyclic quadrilateral, opposite angles are supplementary. </em>

⇒ m∠R + m∠F = 180

⇒ –2 + 6x + 7x – 13 = 180

⇒ 13x – 15 = 180

Add 15 from both sides of the equation, we get

⇒ 13x = 195

Divide by 13 from both sides of the equation, we get

⇒ x = 15

<u>To find the measure of angle E:</u>

m∠E = 5x

m∠E = 5(15)

m∠E = 75

The measure of angle E is 75°.
