h/j=15 for j
h = 15j
j = h/15
Sam ordered some books online and spent a total of
$133
. Each book cost
$8
and he paid a total of
$5
for shipping. How many books did he buy?
(a)Write an equation that could be used to answer the question above. First, choose the appropriate form. Then, fill in the blanks with the numbers
133
,
8
, and
5
. Let
b
represent the number of books.
16×8+5=133😀
To solve the equation h/j = 15 for j, we will isolate the variable j.
1. Multiply both sides of the equation by j to eliminate the denominator:
(h/j) * j = 15 * j
h = 15j
2. Divide both sides of the equation by 15 to isolate j:
(h/15) = (15j)/15
h/15 = j
Therefore, the solution to the equation h/j = 15 for j is j = h/15.
