Answer:

x

Step-by-step explanation:

\frac{7-2x}{-4} +2

Subtract 2 from both sides

\frac{7-2x}{-4}

mutliply both sides by -4, flip the inequality

7-2x >4x+8

Add 2x on both sideds

7>6x+8

Subtract 8 from both sides

-1>6x

Divide both sides by 6

x

Find the value of the variable 7x + 19 11x -89 60°​
I am Lyosha [343]
<h2>7x + 19 = 208</h2><h2>11x - 89 = 208</h2><h2>--------------------------------------</h2>

<u>Step-by-step explanation:</u>

let third angle be x

60° + 60° + x = 180° (Δ sum property)

x = 60°

so, this is a equilateral triangle (all Δ equal)

<h2>-----------------------------------------</h2>

in equilateral triangle --> all sides are equal

so, therefore =>>

7x + 19 = 11x - 89

19 + 89 = 11x - 7x

108 = 4x

108 ÷ 4 = x

27 = x

<h3>x = 27</h3><h2>-----------------------------------------</h2>

so variable

1.) 7x + 19

= 7(27) + 19

= 189 + 19

= 208

2.) 11x - 89

= 11(27) - 89

= 297 - 89

= 208

The first step in solving 3.17 t - 2.431 = 5.06 is to divide both sides of the equation by 3.17. TrueFalse
Pavlova-9 [17]

Answer:

False

Step-by-step explanation:

3.17t - 2.431 = 5.06 \\ 3.17t = 5.06 + 2.431 \\ 3.17t = 7.491 \\  \frac{3.17t}{3.17}  =  \frac{7.491}{3.17}  \\ t = 2.363
