Answer:
x = 5/6-4y^2
Step-by-step explanation:
^ = to the power of and * = times
y = square root of 6x-5/4x
(times by the square root on either side, sorry I don't know how to word it)
y^2=6x-5/4x
(times by 4x either side)
4xy^2= 6x-5
(+5 either side)
4xy^2+5=6x
(-4xy^2 either side)
5=6x-4xy^2
(factorize)
5=x(6-4y^2)
(divide by (6-4y^2))
5/6-4y^2 = x or x = 5/6-4y^2
Tell me if this is incorrect.
Answer:
The correct option is (b).
Step-by-step explanation:
We need to find the probability of getting 5 when Janet rolls a regular eight-sided die with numbers 1 to 8.
The formula for probability of getting an event is given by :
Here, favourable outcome = 1
Total outcomes = 8
So,
So, the correct option is (b).
Jenna need 2 days to make jam if she wants to jar 12 litres of jam in all.
Step-by-step explanation:
The equation shows the amount of jam Jenna has jarred is related to the number of days she has spent making jam.
where j represents the amount of jam jarred and d represents the number of days spent making jam.
To find the number of days that Jenna will need if she wants to jar 12 litres of jam is to substitute in
Dividing 6 on both sides, we get,
Thus, Jenna need 2 days to make jam if she wants to jar 12 litres of jam in all.
