Answer:

x = -2

Step-by-step explanation:

14 - (x + 5) = 3(x + 9) - 10

14 - x - 5 = 3x + 27 - 10

14 - x - 5 = 3x + 17

9 - x = 3x + 17

-x = 3x + 8

-4x = 8

-x = 2

x = -2

erma4kov [3.2K]

Answer:

66.96

Step-by-step explanation:

Furlong = 1/8 mile

Fortnight = 14 days

Day = 24 hours

If the speed limit is 180,000 furlongs per fortnight, converting the units from furlongs per fortnight to miles per hour:

$V=180000\frac{furlong}{fortnight}*\frac{1\ mile}{8\ furlong}*\frac{1\ fortnight}{14\ days}*\frac{1\ day}{24\ hours} \\V=66.96\ mph$

The speed limit on this exotic land in 66.96 miles per hour.

The length of a rectangle is 7 meters longer that it’s width. What is the width of this rectangle if it’s perimeter is equal to

dolphi86 [110]

The width of rectangle is 21 meters.

Step-by-step explanation:

Given,

Perimeter of rectangle = 98 meters

Width of rectangle = w

Length of rectangle = w+7

Perimeter of rectangle = 2(Length+Width)

Perimeter = $2(w+7+w)$

$98=2(2w+7)\\98=4w+14\\98-14=4w\\84=4w\\4w=84$

Dividing both sides by 4

$\frac{4w}{4}=\frac{84}{4}\\w=21$

Width of rectangle = 21 meters

The width of rectangle is 21 meters.
