Step-by-step explanation:
why ? you did it right there already.
the numerator is the top part of the fraction, the "counting" part (how many units of a certain type or size are there).
the denominator (the bottom part) is defining the type or size of units described by the fraction.
so, we are adding 4 to the numerator of 2/5, making it (2+4)/5 = 6/5
what do we need to add to the denominator (the bottom part) to make the fraction have the value of 1/2 ?
so, what x would make 6/x = 1/2 ?
6 = x/2
x = 6×2 = 12
so, we need to get 12 in the denominator, where we have currently 5.
therefore, we need to add 12-5 = 7 to it.
so that
6/(5+7) = 6/12 = 1/2
Step-by-step explanation:
volume = [(15×11)+(½×15×8)] x 12
= (165+60) x 12
= 225×12
= 2,700 cm³
The bells will ring together again at 10:00am I believe.
Given:
The values of a linear function are 
and 
.
To find:
The linear function.
Solution:
If a linear function passes through two points, then the equation of the linear function is:
The values of a linear function are and . It means the function passes through the points (-9,8) and (0,1). So, the equation of the linear function is:
Adding 8 on both sides, we get
Putting 
, we get
Therefore, the required linear function is .
The length of rectangular swimming pool = 25 feet
The width of the swimming pool = 12 feet
The pool is surrounded by a fence which is h feet from each side
So, length of fence becomes = 25+2h
Width of fence becomes = 12+2h
The expression for the length of the fence is 25+2h feet
2h because 'h' increases for both ends of the length of the pool.
