You can find the slope of an equation by looking at what number comes before x. Making the slope being -1/2 because that's the number that comes before x.
Answer: You can divide a number by a fraction by flipping over the fraction and multiplying them together.
Step-by-step explanation:
For example:
Lets say we wanted to divide 8 by 3/4
8÷
Change the division symbol into multiplication, and flip over the fraction (a great way to remember doing this is to remember the phrase <em>Copy Dot Flip </em>- Copy the first digit as it is, put a dot for multiplication, and then flip the fraction over)
8 ·
Now, just multiply and reduce/simplify the fraction if needed
<u>Final answer is </u><u>, no need to simplify or reduce</u>
Hope that helps!!
Answer:
9
Step-by-step explanation:
Vertical lines are parallel so the given interior angles are supplementary and their sum is equal to 180:
4x + 9 + 16x - 9 = 180 add like terms
20x = 180 divide both sides by 20
<u>x = 9</u>
Yes because all sides would be equal to 5 which would give you 5*4 = 20 units.
