Movies are on sale for 3/
vredina [299]

Answer:

$7.50

Step-by-step explanation:

3/4 of the original price

Original price: $10

So we need 3/4 of $10

10 ÷ 4 = 2.5

2.5(3) = 7.5

3/4 of $10 = 7.5, so the price is now $7.50

What is 3x3-45 divided by (4+1)
Lorico [155]

Answer:

3x3-45÷(4+1) is 0.

Step-by-step explanation:

We have to do order of operations so we follow PEMDAS:

P is for Parentheses so we do what's in parentheses first:

(4+1)=5

E is for Exponents but we don't have exponents.

Next is M and D for Multiplication and Division. We have division before multiplication so we should do division first:

45÷5=9

We now have multiplication:

3x3=9

Now we have A and S for addition and subtraction

We don't have addition so we'll do subtraction:

9-9=0

The final answer is 0.

Hope this helps! :)

Hey there! I'm happy to help!

We start out with 3.

Our mom gives us 10.

3+10=13

Our dad gives us 30.

13+30=43

Our aunt and uncle give us 100.

43+100=143

And we have another 7.

143+7=150

Therefore, we have $150 now.

Have a wonderful day! :D
