<h2>Answer:</h2><h2>2) B. 30</h2><h2>3) B. a triangle with measurements of 2, 3 and 5 inches .</h2>

Step-by-step explanation:

2) 85° = (3x - 5)° <em>[</em><em>Vertically</em><em> </em><em>Opposite</em><em> </em><em>Angles</em><em>]</em>

=> 3x - 5 = 85

=> 3x = 85 + 5

=> 3x = 90

=  > x =  \frac{90}{3}

=> x = 30

<em><u>Hence</u></em><em><u>,</u></em>

<em><u>Required</u></em><em><u> </u></em><em><u>value</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>x</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>30</u></em>

3) B. a triangle with measurements of 2, 3 and 5 inches

<em><u>AS</u></em><em><u>,</u></em>

<em><u>Here</u></em><em><u>,</u></em>

2 + 3 = 5.

<em>And</em><em> </em><em>according</em><em> </em><em>to</em><em> </em><em><u>Triangle</u></em><em><u> </u></em><em><u>Inequality</u></em><em><u> </u></em><em><u>Property</u></em><em><u> </u></em><em> </em><em>measurement</em><em> </em><em>of</em><em> </em><em>any</em><em> </em><em>two</em><em> </em><em>sides</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>triangle</em><em> </em><em>should</em><em> </em><em>be</em><em> </em><em>greater</em><em> </em><em>than</em><em> </em><em>the</em><em> </em><em>third</em><em> </em><em>side</em><em>. </em>

<em>So</em><em> </em><em>a</em><em> </em><em>triangle</em><em> </em><em>can't</em><em> </em><em>be</em><em> </em><em>made</em><em>.</em>

Solve.<br> 7x+2y=2,<br> x-2y=14
balu736 [363]
Isolate the X in the second equation

x=2y+14

Substitute that in for the x in the fist equation

7(2y+14) + 2y = 2

Distribute the 7

14y+14+2y=2

Combine like terms

16y+14=2

Isolate the 16y

16y=-12

Isolate y by dividing the whole equation by 16

y=-12/16

Simplify

y=-3/4

That is your y. To find x, plug y into one of the equations. I'm plugging it into the version of the second equation after we isolated x.

x=2(-3/4)+14

Distribute the 2

x=(-1.5)+14

Simplify

x=12.5

Whats the value of n? <img src="https://tex.z-dn.net/?f=40%20%3D%20-%5Cfrac%7B5n%7D%7B8%7D" id="TexFormula1" title="40 = -\frac{
adell [148]

Isolate the n. First, multiply 8 to both sides

40(8) = (-5n/8)(8)

40(8) = -5n

Multiply.

320 = -5n

Isolate the n. Note the equal sign. What you do to one side, you do to the other. Divide -5 from both sides

(320)/-5 = (-5n)/-5

n = 320/-5

n = -64


-64 is your answer for n

hope this helps
