In order to find the diameter, multiply the radius by two. 2 x 4 = 8
Answer:
x=32
Step-by-step explanation:
The equation for direct variation is y =kx
We need to find the constant of variation k
-85 = k*17
Divide by 17
-85/17 = k
-5 = k
y = -5k
When y = -160
-160 = -5x
Divide by -5
-160/-5 =-5x/-5
32=x
Answers: The page numbers are 11 and 12
==========================================================
Explanation:
Consecutive integers are ones that follow immediately after another. For example, the set {7,8,9,10} are consecutive.
Let,
- x = first page, some positive whole number
- x+1 = second page, follows immediately after page x
Adding those two said pages will lead to 23
first + second = 23
(x) + (x+1) = 23
2x+1 = 23
2x = 23-1
2x = 22
x = 22/2
x = 11 is the first page
x+1 = 11+1 = 12 is the second page
Check: 11+12 = 23 which confirms the answers.
