Answer:

The only correct choice is <em>' E '</em> .

Step-by-step explanation:

A.  Trapezoid . . . no; a trapezoid has one pair of parallel sides.

B.  Parallelogram . . . no; a parallelogram has two pairs of parallel sides.

C.  Rhombus . . . no; a rhombus is a parallelogram AND all four of its sides have the same length.

D.  Square . . . no; a square is a parallelogram AND it's a rhombus AND its angles are all 90 degrees.

F.  Rectangle . . . no; a rectangle is a parallelogram AND its angles are all 90 degrees.

The shape in the picture doesn't have ANY of these characteristics or features.  All it has going for it is four sides.  That's a 'quadrilateral'.

Paul went on a bike ride of 30 miles. He realized that if he had gone 8 mph faster, he would have arrived 12 hours sooner. How f
lara [203]

Answer: He actually rode 2 miles per hour on his trip

Step-by-step explanation: Maybe unconventional, but express the time it took, then figure the speed.

Time  = distance /speed  t will represent time, s is the speed:  t = 30/s Use the rime it would have taken at the higher speed to create an equation:

t-12 = 30/s+8   replace the y with the 30/s

30/s -12 = 30/s+8

(s)(30/s -12 ) = (s)(30/s+8 )  Cross multiply to cancel denominators  

(s-8)(30 -12s) = (s-8)(30s/s+8 ) ==> 30s +240 -12s² -96s =30s   Simplify:  

(-1)(-12s² -96s +240 ) =0 ==>  12s² +96s -240  divide all by 12

s² + 8s -20 = 0   Factor and solve for s

(s +10)(s -2) =0    s-2=0   S= 2  

Proof:

30/2 = 15 hours for original trip at 2mph,  

increase speed by 8mph   2 + 8 = 10mph

30 miles at 10mph takes 3 hours; that is 12 hours less than his actual trip.

Can anyone explain the method for algebraic fraction? We have to do it for maths, and i'm really struggling with it. Here is an
riadik2000 [5.3K]

Answer:

x=3

Step-by-step explanation:

The approach is not very different from regular fractions.

You have to get to a common denominator to be able to add them.

10 is a good denominator (multiply the denominators).

multiply the first term by 5, and the second one by 2:

\frac{5 \cdot (x+1)}{5 \cdot 2} + \frac{2 \cdot (x+2)}{2 \cdot 5}  = 3

\frac{5x+5 + 2x+4}{10} = 3

\frac{7x+9}{10} = 3

7x + 9 = 30

7x = 30 - 9

x = 3

let me know if you need more details on one of the steps
