Answer:No, he doesn't have enough buttons. He needs 5 more.
Step-by-step explanation: Do 15×5. Each of the 15 snowmen need 5 each, which equals 75 buttons. Since he has 70 buttons to start off with, he only needs five more buttons.
<u>Answer:</u>
The line parallel to y – axis is x = 4. Thus option a is correct.
<u>Solution:</u>
Given, a set of options as linear equations.
We have to choose one which is parallel to the y – axis.
We know that, slope of y – axis is undefined.
As the required line is parallel to the y – axis, its slope should also be equal to slope of y – axis.
Now, let us check one by one option.
Now, a) x = 4
![\rightarrow \text { slope }=\frac{-x \text { coeffiecient }}{y \text { coefficient }}=\frac{-1}{0}](https://tex.z-dn.net/?f=%5Crightarrow%20%5Ctext%20%7B%20slope%20%7D%3D%5Cfrac%7B-x%20%5Ctext%20%7B%20coeffiecient%20%7D%7D%7By%20%5Ctext%20%7B%20coefficient%20%7D%7D%3D%5Cfrac%7B-1%7D%7B0%7D)
= undefined
Here slope of this line is undefined. Which means it is parallel to y – axis.
So, we got our required answer.
Hence, the line parallel to y – axis is x = 4 i.e. option a is correct.
4 1/10=41/10
2 2/5=12/5
41/10*12/5. =492/50
Divide 492 by 50=9 42/50. Or 9 21/25
