Answer: x = 12, y = 50

Step-by-step explanation: 2y-5 and 95 are vertical angles and vertical angles are always congruent (equal). So, 2y - 5 = 95. 2y = 100. y = 50. Solving for x is slightly more difficult. 3x and 144 are linear pairs and linear pairs are adjacent and equal 180° because a straight line is 180°. So 3x + 144 = 180. 3x = 36. x = 12.

How do I do this? (3x^2+8)-(2x^2+1)<br> So first I add like terms?<br> 5x^2 + 8 + 1

Gemiola [76]

<span> (3x</span>² <span>+ 8) - (2x</span>² <span>+ 1)
= </span>3x² + 8 - 2x² - 1
= 3x² - 2x² + 8 - 1
= x² + 7

The simplified form of the equation is $\rm -69.19x+38.2$ .

<h2>Given that</h2>

Equation; $\rm -9.2(8x - 4) + 0.7(2 + 6.3x)$

<h3>We have to determine</h3>

The simplified form of the equation;

<h3>According to the question</h3>

To determine the simplified form of the equation following all the steps given below.

Equation; $\rm -9.2(8x - 4) + 0.7(2 + 6.3x)$

<h3>To simplify the equation multiple the terms and solve.</h3>

Then,

The simplified form of the equation is,

$\rm =-9.2(8x - 4) + 0.7(2 + 6.3x)\\
\\
= (-9.2) (8x)- (-9.2)(4) + (0.7)(2) + (0.7) (6.3x)\\
\\
=-73.6x -(-36.8) +(1.4)+(4.41x)\\
\\
= -73.6x+36.8+1.4+4.41x\\
\\
=-69.19x+38.2$
