Hello from MrBillDoesMath!

Answer:

-3


Discussion:

First observe that 4 is a common denominator of each fraction:


-5 1/2  +  6 3/4   - 4 1/4 =          (convert 1/2 = 2/4)

-5 2/4 + 6 3/4 - 4 1/4   =

(-5 + 6 - 4 ) + ( -2/4 + 3/4 - 1/4) =

(1 - 4 )        + (-3/4 + 3/4) =

-3 + (0) =

-3


Thank you,

MrB

Simplify expression 1/4 •3(8a-5b-4)-(4a+1)+4b
pychu [463]

Answer:

(8a+b-16)/4

Step-by-step explanation:

1/4×3(8a-5b-4)-(4a+1)+4b

Simplify:

-4a-1+4b+1/4×3×8a-1/4×3×5b-1/4×3×4

=1/4xax24-4a-1/4bx15+4b-1/4×12-1

=1ax24/4 -4a - 1bx15/4 +4b -1×12/4 -1

=ax24/4 -4a -bx15/4 + 4b -12/4 -1

= -4a + 24a/4 + 4b - 15b/4 -1 -3

= -4a + 6a + 4b - 15b/4 - 4

= 2a + 4b - 15b/4 - 4

= 8a + 16b - 15b - 16 / 4

= (8a + b - 16) / 4

= 8a + b - 16 / 4

The perimeter of a rectangle is 200 feet. Describe the possible lengths of a side if the area of the rectangle is not to exceed
slavikrds [6]
Length=x
width=y
Perimeter of a rectangle=2(length)+2(width)
Therefore:
2x+2y=200
We simplify the equation dividend both sides of this equation by 2:
x+y=100  
Then:
y=100-x

Area of a rectangle: length x width
We have the next inequation: 
x(100-x)<900
100x-x²<900
x²-100x+900<0

We solve this inequation
1) we solve this equation:
x²-100x+900=0
x=[100⁺₋√(10000-3600)]/2=(100⁺₋80)/2
We have two solutions in this equation:
x₁=90
x₂=10

2)With these values, we make intervals:
(-∞,10)
(10,90)
(90,∞)

3)With these intervals, we check it out if the inequation works: 
(-∞,10); for example; if x=0 ⇒ 0²-100(0)+900=100>0, this interval don´t work.
(10,90);f.e: if x=11; ⇒ 11²-100(11)+900=-79<0, this interval works.
(90,∞); fe; if x=91 ⇒91²-(100)91+900=81>0; this interval don´t work.

answer: the possible lengths would be the values inside of this interval:
(10,90) ft.
