Answer:
Step-by-step explanation:
P(BA)=P(B)+P(A)-P(AnB)
= 0.51+0.8-0.468
=1.31-0.468
=0.842
P(BA) = 0.842
1. k+5=11
2. 7n=42
3. l+13=17
4. 10- p²=9
5. x²+y²=4
Answer:
x =50
Step-by-step explanation:
Answer:

Step-by-step explanation:
This is the answer because:
1) Reduce the expression, if possible, by cancelling the common factors.
2) You can also find the reciprocal of 1 1/2 = 3/2 while dividing the expression:
1. Convert both fractions into improper fractions:


2. Divide both fractions:
÷
=
x
=
= 
Therefore, the answer is

Answer:
x = 0,3
Step-by-step explanation:
y-10x=5 move -10x to the other side to get y by itself
y=10x+5 then you would substitute this equation into the other equation where you see y
10x+5=x^2+7x+5 move everything to one side
0=x^2+7x+5-10x-5 combine like terms
0=x^2-3x factor
0 = x(x-3) set each equal to zero
x=0
x-3 = 0 add 3 to both sides
x = 3
the answer is x=0 and x=3
