Answer:
(30-5n)
Step-by-step explanation:
The given sequence is :
25,20,15,10,5
Here,
First term, a = 25
Common difference = 20-25 = -5
We need to find the nth term of the given sequence. The formula for the nth term is given by :

So, the nth term of the above sequence is (30-5n).
This is your equation

4/3 x 3.14 x
8 ^{3}
4/3 x
3.14 x 5124/3 x 1607.68
2143.57 (I also got 2144.66 if the first one doesn't work)
Answer:
1/6

Answer:
y = 17.5
Step-by-step explanation:
Given that y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition y = 42 when x = 84, then
42 = 84k ( divide both sides by 84 )
0.5 = k
y = 0.5x ← equation of proportion
When x = 35, then
y = 0.5 × 35 = 17.5
Answer:
5
Step-by-step explanation:
For the point to be a solution to the equation, it has to lie on the line 5x -2y= 30 and therefore must satisfy the equation.
5x -2y= 30
When x=8,
5(8) -2y= 30
40 -2y= 30
40 -30= 2y (bring constant to 1 side)
2y= 10 (simplify)
y= 10 ÷2
y=5
Thus the missing value is 5.
