Answer:

x > -99/4

Step-by-step explanation:

(−2/5)(x)−9<9/10

Simplify both sides of the inequality.

−2/5x−9<9/10

Add 9 to both sides.

−2/5x−9+9<9/10+9

−2/5x<99/10

Multiply both sides by 5/(-2).

(5/−2)*(−2/5x)<(5/−2)*(99/10)

x>−99/4

the perimeter of a rectangle is 192 ft. the ratio of its length to its width is 7:5 what are dimensions of the rectangle?
Jobisdone [24]

Answer:  Hence the dimensions are 56 ft and 40 ft.

Step-by-step explanation:

Alright, lets get started.

The ratio of sides of rectangle is given as 7:5.

It means, the length of rectangle is : 7x

It means, the width of rectangle is : 5x

So the perimeter of rectangle will be : 2(length + width)

Plugging the value of sides length and width,

the perimeter of rectangle will be : 2\times(7x+5x)

the perimeter of rectangle will be : 2\times 12x

the perimeter of rectangle will be : 24x

As per question, the given perimeter is 192, so

24x=192

Dividing 24 in both sides,

x=\frac{192}{24}

x=8

Hence the length of rectangle will be : 7\times 8 =56

Hence the width of rectangle will be : 5\times 8 =40

Hence the dimensions are 56 ft and 40 ft.  :   Answer

Hope it will help :)
