Answer:
The correct answer is Option 3: 12y
Step-by-step explanation:
A polynomial term is usually made of a variable and a co-efficient.
Like terms are those terms that have the same variables i.e. x and 44x are like terms.
Given expression is:
All the terms have only y which means that all three terms are alike.
The coefficients of like terms are added or subtracted according to their sign.
= 12y
Hence,
The correct answer is Option 3: 12y
Answer:
9 red tiles
Step-by-step explanation:
Total number of tiles:
Total number of red tiles:
Probability of getting red in one draw:
<em>This means that you would expect to get red or 30% of the times.</em>
<em>Hence, when you draw tiles 30 times from the bag, you would expect red to be picked 30% of 30 times. This is:</em>
<em></em>
So, you would expect to draw a red tile from the bag 9 times.
If we know that the WHOLE angle added is 105 and only part is 75 you need to subtract the whole angle and subtract from part of the whole angle.
105-75=30. You get 30 And that’s you answer!
