Okay so lets look at what it says.
Opposite in the case of math almost always means negative. So (2(-n)+5)*2. This can be simplified to (-2n+5)*2 = 22 + n
Again, simplify it and its -4n+10 = 22 + n
Subtract 10 from both sides and its -4n = 12 + n
Add 4n to both sides and you get 0 = 12 + 5n
Subtract 12 from both sides and its 5n = -12.
Divided both sides by five and you have n = -12/5
Answer:
A. P(A l B) = x
Step-by-step explanation:
For independent events A and B,
P(B | A) = P(B)
P(A | B) = P(A)
P(A ∩ B) = P(A)P(B)
If P(A) = x and P(B) = y then:
⇒ P(B | A) = y
⇒ P(A | B) = x
⇒ P(A ∩ B) = xy
Therefore, the correct solution from the options given is:
A. P(A l B) = x
The answer should be A and D
First you need to get the unit rate by dividing 715 by 13, getting 55 miles per hour. You then will need to divide 495 by 55 to get the answer of 9
For odd integers,
(2x+1)=odd
.
3 consecutive odd integers,
x + (2x + 1) + (4x + 1)
= 7x + 2
