Answer:
1.5
Step-by-step explanation:
k= y/x
y= 12-4.5 = 7.5
x= 8-3 = 5
k = 7.5/5 = 1.5
Let the first integer be x; then the second is x+1.
The product of x and x+1 is x(x+1), and this product must equal 1295.
Thus, x^2 + x = 1295, or x^2 + x - 1295 = 0
Solve for x by completing the square:
x^2 + x + (1/2)^2 - (1/2)^2 - 1295 = 0
(x-1/2)^2 - 1/4 - 1295 = 0, or (x-1/2)^2 -5181/4 = 0,
Thus, x-1/2 = sqrt(5181/4), and so
x = 1/2+sqrt(5181/4) = 25.45
This could NOT be correct, since x and x+1 are CONSECUTIVE INTEGERS.

Answer:
B
Step-by-step explanation:
Answer:
if 'h' is equal to 4+2= 6
then it would be
w = 4 (6)
w = 24
60 seconds = 1 minute
60/15 = 4
12 hops in 15 seconds is the same as
4 * 12 hops in 4 * 15 seconds, or
48 hops in 60 seconds, and since 60 sec = 1 min, it equals
48 hops per minute.
