Answer:

818.4 in²

Step-by-step explanation:

shaded region = area of sector - area of triangle

area of sector = area of circle × fraction of circle

A = π × 27.8² × $\frac{150}{360}$ ≈ 1011.65 in²

area of triangle = 0.5 × 27.8 × 27.8 × sin150° ≈ 193.21 in²

shaded region = 1011.65 - 193.21 ≈ 818.4 in²

Solve the equation. 25=9x+4-6x

raketka [301]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{x = 7}}}}}$

Step-by-step explanation:

$\star{ \tt{ \: 25 = 9x + 4 - 6x}}$

$\sf{Step \: 1 \: }$ : Collect like terms

Like terms are those which have same base

$\longmapsto{ \sf{25 = 3x + 4}}$

$\tt{Step \: 2 \: }$ : Swap the sides of the equation

$\longmapsto{ \sf{3x + 4 = 25}}$

$\tt{Step \: 3 \: }$ : Move 4 to right hand side and change it's sign

$\longmapsto{ \sf{3x = 25 - 4}}$

$\tt{Step \: 4}$ : Subtract 4 from 25

$\longmapsto{ \sf{3x = 21}}$

$\tt{Step \: 5}$ : Divide both sides by 3

$\longmapsto{ \sf{ \frac{3x}{3} = \frac{21}{3}}}$

$\tt{Step \: 6}$ : Calculate

$\longmapsto{ \sf{x = 7}}$

The value of x is 7

Hope I helped!

Best regards! :D
