Answer:
3y-x=2
x=−2+3y
y=2/3+x/3
-2y-x=18
y=9-x/2
x=18-2y
Step-by-step explanation:
<span> 6.022 x 1023 i think thats how much
</span>
Okay, let's work this out.
<span><span><span>3x</span>+70</span>−<span>7x</span></span><span>=<span><span><span><span>3x</span>+70</span>+</span>−<span>7x
</span></span></span>Combine Like Terms:<span>=<span><span><span>3x</span>+70</span>+<span>−<span>7x</span></span></span></span><span>=<span><span>(<span><span>3x</span>+<span>−<span>7x</span></span></span>)</span>+<span>(70)</span></span></span><span>
=<span><span>−<span>4x</span></span>+<span>70
Answer -4x+70
I really don't understand what you mean by this, perhaps you wrote the question wrong, but it would be great than 18.

The value of p(a) is 0.5
Mutually exclusive events are those events that do not occur at the same time
Given,
The a and b are mutually exclusive events
P(a AND b)=0
P(a)=0.48
p(a or b)=0.98
We know that,
P(a or b)=P(a)+P(b)-P(a AND b)
P(a or b)=P(a)+P(b)-0
P(a or b)=P(a)+P(b)
P(a)=P(a or b)-P(b)
Substitute the given values
P(a)= 0.98-0.48
P(a)=0.5
Hence, the value of P(a) is 0.5
