Step-by-step explanation:

y = 4x – 5

-4x + y = -5

y = 2x + 3

-2x + y = 3

Elimination

-4x + y = -5

-2x + y = 3

__________--

-2x = -8

x = -8/-2

x = 4

Subsitution

-2x + y = 3

-2(4) + y = 3

-8 + y = 3

y = 3 + 8

y = 11

Jeremy built an office with a floor area of 55/14 square feet. The office is rectangular in shape. If the length of the room is
Alexxandr [17]

Answer:

110/289 feet

Step-by-step explanation:

Step one:

given data

Area of the floor= 55/14 square feet.

The length of the floor= 8 1/2 feet-----convert to simple fraction= 17/2 feet

Step two:

The expression for the area of the room is

Area= L*W

55/14= 17/2*W

55/14=17W/2

cross multiply

17W*14=55*2

289W=110

divide both sides by 289

W= 110/289 feet
