Answer:
15
Step-by-step explanation:
If they started of paying 15 then that's your constant. So what you do is subtract 15 from 45 and see what's left which will be 30. Since each bag of popcorn is $2 you divide the $30 dollars you have left over by 2 and you'll get 15 for the amount of popcorn bags they'll have to buy.
The Method is that you add 1 block horizontally to the 2nd row of the figure every time you make a new one.
Because one is in the tousandths place other is in the hundredths place!

The solution to (21x) - (-16 + 7x) is 14x + 16
<h3><u>Solution:</u></h3>
Given that (21x) - (-16 + 7x)
We have to evaluate the given expression
Let's look at the given expression
(21x) - (-16 + 7x)
Multiply the terms within second bracket with minus sign
<em><u>There are two simple rules to remember:</u></em>
- When you multiply a negative number by a positive number then the product is always negative.
- When you multiply two negative numbers or two positive numbers then the product is always positive
⇒ (21x) + 16 - 7x
Removing the parenthesis
⇒ 21x + 16 - 7x
Combining the like terms,
⇒ 14x + 16
Thus the solution is 14x + 16
