Answer:
The answer is A.
Step-by-step explanation:
So we have the two equations:

To make a substitution of the second equation into the first equation, we need to isolate the <em>y </em>variable in the second equation. Thus:

Now, we can substitute this into the first equation. Therefore:

The answer is c. Bcs A + B = 90 [ 35 + 55 = 90]
Answer:
Size of |E n B| = 2
Size of |B| = 1
Step-by-step explanation:
<em>I'll assume both die are 6 sides</em>
Given
Blue die and Red Die
Required
Sizes of sets
- 
- 
The question stated the following;
B = Event that blue die comes up with 6
E = Event that both dice come even
So first; we'll list out the sample space of both events


Calculating the size of |E n B|


<em>The size = 3 because it contains 3 possible outcomes</em>
Calculating the size of |B|

<em>The size = 1 because it contains 1 possible outcome</em>
Tim has 2 times as luke
t=2l
they have 29 goether
t+l=39
subsitute
2l+l=39
3l=39
divide by 3
l=13
subsitue
t=2l
t=2(13)
t=26
tim has 26 and luke has 13
I don't know how many marble Tim has but probably all of them since alll must die and then the marbles go to Time
