Answer:
$60
Step-by-step explanation:
12/8 = x/40
40(12/8) = x
60 = x
5 and 1/4 can be 5.25 so all you have to do is divide that by 3 and you’ll get 1.75 per container.
If you wanted to keep it as a fraction, 5 and 1/4 would become 21/4 (you do 5 x 4= 20 + 1) and for fractions I always remembered dividing as ‘Keep, Change, Flip’ so you would do 21/4 for keep. Change would be to change the sign from division to multiplication. And for Flip you would flip 3 over 1 (3/1) to 1/3
Putting that all together would be 21/4 x 1/3 which also equals 21/12 by multiplying the denominators and numerators. Then you simplify, dividing it by 3 to equal 7/4 and another simplify to be 1 and 3/4 which is 1.75.
Hope this helps!
Answer: C. 2n+1
Step-by-step explanation:
The sequence of numbers is
3,5,7,9
The terms are increasing at a linear rate. This means that it is an arithmetic progression. The difference between two successive terms is constant. This is the common difference. The formula for the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
Tn is the nth term of the arithmetic sequence.
d is the common difference of the arithmetic sequence.
n is the number of terms in the arithmetic sequence.
From the information given
a = 3
d = 5 - 3 = 7 - 5 = 9 - 7 = 2
Tn = 3 + 2(n - 1)
Tn = 3 + 2n - 2
Tn = 3 - 2 + 2n
Tn = 2n + 1
