Answer:
B, 7/20
Step-by-step explanation:
If two events are mutually exclusive that means that there is no intersection
so in the union formula: AUB=A+B-A∩B
A∩B=0
we can write P(a)=x
7/10=7/20+x+0
7/10-7/20=x
x=7/20
When solved using the distributive property, it will equal 2b+6c

Answer:
<em>Rental cost</em> of <em>movie</em> is <em>$6.50</em><em> ; </em><em>Rental cost</em> of <em>video game</em> is <em>$2.25</em>
Step-by-step explanation:
4m + 8v = 61 ........ <em>(1)</em>
2m + 3v = 24 ........ <em>(2)</em>
<em>(1)</em> - 2 × <em>(2)</em>
2v = 13
v = 6.5
2m + 3(6.5) = 24
2m = 24 - 19.5
m = 4.5 ÷ 2 = 2.25
<em>Rental cost</em> for each <em>movie</em> is <em>$6.50</em>
<em>Rental cost</em> for each <em>video game</em> is <em>$2.25</em>
