Step-by-step explanation:
6x+3x-5+14=180
9x+9=180
-9 -9
9x=171
/9 /9
x=19
The equation would be 30p+15s=150
The amount of each depends on what you want more of
The answer is f^-1(x)=8/3+x/3
40/100*x=54
40x=5400
40x/40=5400/40
x=£135
the original price is £135
40/100*135=£54
<span>We add the products of the chance a bridge collapses while the other two bridges do not collapse.
P(Only Elder collapses) = .14*.96*.8 = 0.10752
P(Only Younger collapses) = .86*.04*.8 = 0.02752
P(Only Ancient collapses) = .86*.96*.2 = 0.16512
P(Only one bridge collapses) = 0.10752 + 0.02752 + 0.16512 = 0.30016
Round the probability to four decimal places giving the solution of 0.3002 as the probabilityof exactly one bridge collapse in the next year.</span>
