Ste-by-Step Explanation
(a)Total Amount to be paid to the four actors
=500,000+(300,000+0.02x)+(150,000+0.03x)+(80,000+0.08x)
Collect like terms
=500,000+300,000+150,000+80,000+0.02x+0.03x+0.08x
(b)When x=200
<u>Question 2</u>
(a)The two parts of a power are the base and index.
Take, for example, the expression:
Another example using numbers is:
In this case:
(b)Like terms are terms that have the same letter/variable attached to them.
For example, the following pairs are like terms
- 8x and 3x
- 4y and -9y
- 6pq and pq
- 3 and 3
These, however, are not like terms
- 3 and 3y
- 4x and 4y
Hi there!
Looks like a lot of work is going on here.
Let's start by solving this equation for the x.
Step 1) Add -20y to both sides.
Step 2) Divide both sides by 5.
Final Answer:
Now, let's solve for y.
Step 1) Add -5x to both sides.
Step 2) Divide both sides by 20.
Final Answer:
Hope this helps! :D
Hint - When you have two variables in an equation, and you want to solve for one, the other will end up in your answer. :)
