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
Choice d because solid dot means or equal to and greater means to the right

|3x - 2y| + 5
x = -3
y = 2
<u>Step 2: Evaluate</u>
- Substitute: |3(-3) - 2(2)| + 5
- Multiply: |-9 - 4| + 5
- Subtract: |-13| + 5
- Evaluate: 13 + 5

Answer:
3) (5, 10)
Step-by-step explanation:
d + e = 15
-d + e = -5
e = -5 + d
substitude e for -5 + d
d + -5 + d = 15
2d = 10
d = 5
figure out e
5 + e = 15
e = 10
