Answer: 62
Step-by-Step Explanation:
First Term (a) = 7
Common Difference (d) = 12 - 7 = 5
Term to Find (n) = 12th
Therefore, finding the 12th Term :-
=> a+(n-1)d
= 7 + (12 - 1)5
= 7 + (11)5
= 7 + 55
=> 62
Hence, 12th Term of this AP is 62
Answer:
a = 64
Step-by-step explanation:
The geometric mean of 2 numbers a and b is 
, then
= 16
( square both sides )
28a = (16 )² = 1792 ( divide both sides by 28 )
a = 64

/5 Decimal Form: 0.6
Step-by-step explanation:
9) Convert the mixed numbers to improper fractions, then find the LCD and combine.
10) Simplify the expression.
11) To subtract fractions, find the LCD and then combine.
The Volume of the box has to equal 64
because all the sides have to equal 12
and 12/3 = 4
You need to use a system of equations with 2 variables
where x= # of paintbrushes bought
and y= # of paint units bought
the first equation would be
.95x+.99y=4.87
Usually there is more information given in these problems so that you can make the second equation. Did the problem say how many total items were bought or anything else because given this information you cannot make a second equation and therefore cannot solve for both variables. Also, the wording is unclear, did she spend 4.87 on just paintbrushes or both brushes and paint.
