Ok, so after you do -8a+5a, you also have to do 6 -35, getting the equation
-29-3a
Answer: 17 is A and 18 is B
Used a calculator to add them all up! Get some sleep hope this helps.
17) 2(3x8)+2(3x6)+2(6x8) = 180
18) 4(9x2)+2(9x9) = 234
Use the identity P(A ∪ B) = P(A)+P(B)-P(A ∩ B)
P(A)=0.50
P(B)=0.60
P(A ∪ B) = 0.30
=>
P(A ∪ B) = P(A)+P(B)-P(A ∩ B)
=(0.50+0.60)-0.30
=0.80
-5 and -4.
-5 times -4 is 20 while adding -5 and -4 it equals -9. (don't be very harsh if i got this wrong)
Let Mr Gelsomino lost g
Mr Chiarilli lost 240 more than g
so addition is to be used
or
#2
Just opposite
Mr Gelsomino lost 240 less than c
