Simplify this equation<br> -5x+7>22

Lana71 [14]

Answer:

Step-by-step explanation:

Divide both sides by - 5

$\frac{ - 5x}{5} > - \frac{15}{5} \\ x > - 3$

Reverse the sign

We have the final answer as

Answer:

105

Step-by-step explanation:

$A=lw$ $A=$ (.5)πr²

to get the area of the shaded parts you have to subtract the area of the semicircle from the area of the rectangle

$A=(16)(9)$

$A=144$

$A=\frac{(3.14)(5)^2}{2}$ $A=\frac{(3.14)(25)}{2}$ $A=\frac{78.5}{2}$

$A=39.25$

subtract the areas

$144-39.25=104.75$

$104.75$ ≅ $105$
