If you're trying to solve for y
-2y = 8
Divide -2 to both sides
Cancel out the -2 on the left, Divide the -2 to the 8 on the right so
y = -4
The answer is 8 batches of cookies
Answer:
0.9
Step-by-step explanation:
Since A and B are independent hence;
P(A∩B) = P(A)P(B)
Given the following
P(A∩B) = 0.27
P(A) = 0.3
Required
P(B)
Substitute into the formula;
P(B) = P(A∩B)/P(A)
P(B) = 0.27/0.3
P(B) = 0.9
Hence the value of P(B) is 0.9
The relationship between space, time and velocity for a uniform motion is given by:
where
S is the distance covered
t is the time
v is the velocity
The plane in our problem has a velocity of
and so during a total time of t=4 h, the distance it covers is
therefore, 680 miles.
Answer:
see explanation
Step-by-step explanation:
let y = f(x) then rearrange making x the subject
y = 2x - 10 ( add 10 to both sides )
y + 10 = 2x ( divide both sides by 2 )
= x
Change y back into terms of x
(x) =
