Answer:
twice
Step-by-step explanation:
to find expected value multiply probablility and number of events
0.40 times 5 = 2.0
Answer: Rewrite equations:
5x+y=−13;6x+6y=−6
Step: Solve5x+y=−13for y:
5x+y=−13
5x+y+−5x=−13+−5x(Add -5x to both sides)
y=−5x−13
Step: Substitute−5x−13foryin6x+6y=−6:
6x+6y=−6
6x+6(−5x−13)=−6
−24x−78=−6(Simplify both sides of the equation)
−24x−78+78=−6+78(Add 78 to both sides)
−24x=72
−24x
−24
=
72
−24
(Divide both sides by -24)
x=−3
Step: Substitute−3forxiny=−5x−13:
y=−5x−13
y=(−5)(−3)−13
y=2(Simplify both sides of the equation)
Answer:
x=−3 and y=2
Step-by-step explanation:
Answer:
Its length is 3/8× 24 = 9 ft.
So correct option is A.

Answer:
7/11
Step-by-step explanation:
Answer:
A=5
Step-by-step explanation:
5-3a<-10 is the same as
5-3a=-10
So to solve it just solve for a.
subtract 5 from both sides
-3a=-15
dived -3 from both sides to get a alone
A=5
hope this helps!
