12x-39<9 and -4x+3<-6
gulaghasi [49]
Remember, you can do anything to an equation as long as you do it to both sides


and when multiply or divide by a negative in inequalities, flip the direction of the sign

12x-39<9
add 39 to both sides
12x<48
divde bothh sides by 12
x<4



-4x+3<-6
minus 3 both sides
-4x<-9
times both sides by -1 and flip sign
4x>9
divide both sides by 4
x>9/4

If Janet buys a bag for $45.50 and the tax is 5% and she has $60, will she have enough money to buy a $12 movie ticket?
sertanlavr [38]

In this equation, we're trying to find if she has enough money to buy a $12 movie ticket.

We know that she buys a bag for $45.50, with a 5% tax rate. Let's calculate the total cost of the bag after tax.

45.50 · 1.05 = 47.775

Round to the nearest hundredths place

$47.78

She spent $47.78 on the bag.

She has $60, so calculate how much money she has left.

60 - 47.78 = 12.22

She has $12.22 left to spend.

This means that she has enough money to buy the movie ticket.

She would also have 22 cents left to spare.

Answer:

Yes, she has enough money to buy the movie ticket
