Answer:
The answer here is going to be 2x
Because y varies inversely as x, therefore
where k = constant.
When x = 6, y = 2.5. Ther efore
Cross multiply.
k = 6 x 2.5 = 15
The equation is
When x = 4, obtain
Answer: a. 3.75
31.55 this will be your answer
Well, the quotient must be bigger/smaller
lets say the numbers are x and y
x>y
so
x-y=30 and x/y=6
multiply both sides by y in 2nd equation
x=6y
subsitute 6y for x in other equation
6y-y=30
5y=30
divide by 5
y=6
sub back
x=6y
x=6(6)
x=36
the numbers are 36 and 6
but they could also be -36 and -6 because -36/-6=6 and -6-(-36)=30
the 2 numbers are 36 and 6 or -36 and -6
Problem 16
Divide both sides by 2 to undo the multiplication of 2 (done to the t).
2t > 324
2t/2 > 324/2
t > 162
Answer: t > 162
=====================================================
Problem 17
Similar to problem 16, we will divide both sides by 12
12y >= 1
12y/12 >= 1/12
y >= 1/12
Answer: y >= 1/12
Note: the symbol ">=" without quotes means "greater than or equal to".
=====================================================
Problem 18
To undo the division of 9.5, we multiply both sides by 9.5
x/9.5 < 11
9.5*x/9.5 < 9.5*11
x < 104.5
Answer: x < 104.5
