ozzi

Answer:

slope= 11

Step-by-step explanation:

(12,23) = (x1,y1)

(14,45) = (x2,y2)

Now,

slope(m)= (y2-y1)/(x2-x1)

=(45-23)/(14-12)

=22/2

If 75% of a number is 255 and 20% of the same number is 68, find 95% of that<br> number.
Tanzania [10]

Answer:

75% may also be expressed as 75/100=3/4 or as 0.75 as needed.

 

Let x = the number

 

Translate:

 "if 75% of a number is 60"       means

     (75/100)  *  x      =  60            [the word "of" usually means multiply]

     (3/4) x = 60                           [reduce or just write it this way]

        x  = 60(4/3)                       [multiply both sides by  4/3]

        x = 80
