Answer:
2177.5
Step-by-step explanation:
5x435.5=2177.5
For inverse variation, y = k/x
From the given, 9 = k/8
k = 9 * 8 = 72
Thus, y = 72/x
Therefore, when x = 32, y = 72/32 = 2.25
y = 2.25
Answer:
x= -7
Step-by-step explanation:
You need to first add 5 to the -5. Even though the - is a subtraction sign, you can still count it as a subtraction sign. In order to balance it out again, so you add the 5 to the 16. 16+5=21, so the equation would be -3x=21. To get x by itself, you divide by -3. So, -3x/-3 and 21/-3. That gets rid of the -3, and you get a -7 as an answer.
