Answer:
the quotient can also be the solution to a division problem involving two fractions. since division is the opposite of multiplication, you can turn this division problem into a multiplication problem by multiplying the top fraction by the reciprocal of the bottom fraction
Sales tax is $42 on a $600 item, so
sales tax rate = 42/600 = 7%
Tax on $930 item
=$930 * sales tax rate
=$930*7%
=$65.10
3x^2 + 6x - 24
3(x^2 + 2x - 8)
3(x + 4)(x - 2) <==
3(x - 2) = 12
Distribute 3 inside the parentheses.
3x - 6 = 12
Add 6 to both sides.
3x = 18
Divide both sides by 3.
