What is the value of x? Enter your answer in the box. x =

Oliga [24]

$\star \blue{ \frak{To \: find :}}$

$\\ \\$

value of x

$\\ \\$

$\star \blue{ \frak{solution:}}$

$\\ \\$

So to find value of x , we have to apply Linear Pair.

$\\ \\$

Equation formed:

$\\ \\$

$\bigstar \boxed{ \tt(10x - 20) \degree + (6x + 8)\degree = 180 \degree} \\$

$\\ \\$

Step by step expansion:

$\\ \\$

$\dashrightarrow \sf(10x - 20) \degree + (6x + 8)\degree = 180 \degree \\$

$\\ \\$

$\dashrightarrow \sf10x - 20 \degree + 6x + 8\degree = 180 \degree \\$

$\\ \\$

$\dashrightarrow \sf10x +6x- 20 \degree + 8\degree = 180 \degree \\$

$\\ \\$

$\dashrightarrow \sf16x- 20 \degree + 8\degree = 180 \degree \\$

$\\ \\$

$\dashrightarrow \sf16x- 12\degree = 180 \degree \\$

$\\ \\$

$\dashrightarrow \sf16x = 180 \degree + 12\degree\\$

$\\ \\$

$\dashrightarrow \sf16x =192\degree\\$

$\\ \\$

$\dashrightarrow \sf \: x = \frac{192\degree}{16\degree} \\$

$\\ \\$

$\dashrightarrow \sf \: x = 12 \degree$

$\\ \\$

$\therefore \underline {\textsf{\textbf{Value of x is \red{12\degree}}}}$

Solve the following inequality for y y/3 - 7 ≥ 2/3

astra-53 [7]

Answer:

y≥ 23

Step-by-step explanation:

y/3 - 7 ≥ 2/3

Add 7 to each side

y/3 - 7+7 ≥ 2/3+7

y/3 ≥ 2/3+21/3

y/3 ≥ 23/3

Multiply each side by 3

y/3 *3 ≥ 23/3*3

y≥ 23
