Answer:
Answer:The equation for inverse proportion is x y = k or x = k/ y. Therefore, for finding the value of the constant k, you can use the known values and then use this formula to calculate all the unknown values.

Answer: 0
Step-by-step explanation: 18a + 3 = 3
-3 -3
--------------
18a = 0 you can't divide 18 and zero it would be 0
Answer:
Step-by-step explanation:
The surface area formula for pyramids is given by :
...(1)
We need to arrange the formula for l.
Take b to LHS,
![S-b=\dfrac{1}{2}Pl\\\\2(S-b)=Pl\ [\text{cross-multiplying}]\\\\l=\dfrac{2(S-b)}{P}](https://tex.z-dn.net/?f=S-b%3D%5Cdfrac%7B1%7D%7B2%7DPl%5C%5C%5C%5C2%28S-b%29%3DPl%5C%20%5B%5Ctext%7Bcross-multiplying%7D%5D%5C%5C%5C%5Cl%3D%5Cdfrac%7B2%28S-b%29%7D%7BP%7D)
So, the expression is 
for the slant height.
Answer:
3 hours 39 minutes
Step-by-step explanation:
4:33 + 0:39 = 5:12
5:12 + 3:00 = 8:12
Answer:
x=21
Step-by-step explanation:
Notice the right angle. Perpendicular to it on the right, we have two complementary angles, 25, and 3x+2 (you can ignore the parentheses basically). Because they are complementary angles, they will add up to 90, so we can make an equation to solve for x:
25+3x+2=90
3x+2=65
3x=63
x=21
So x=21 is the correct answer. Let me know if you have any questions about my explanation.
