Answer:
1)-n-5m
2)-13n+10m+6mn
Step-by-step explanation:
1) (6n-7n)-5m= -n-5m
2)(n-7n-7n)+(2m+2m+6m)+6mn= -13n+10m+6mn
Answer:
The probability is 2/5 that a $20 bill will be drawn from the wallet.
Step-by-step explanation:
There are 20 total bills in the wallet (5 $5, 7 $10, and 8 $20, 5+7+8=20). So if the finder and returner of the wallet was to be given one of the bills drawn from the wallet there would be an 8/20 chance the owner of the wallet would pull a 20. That's because there are 20 total bills in the wallet and 8 of them are $20.
Simplifying 8/20... 8/20= 4/10= 2/5.
So, there is a 2/5 chance that a $20 bill will be pulled out of the wallet.
Hope this helps!
3.05, but if you need sig figs, you should check that
Answer:
it might be 48.9 but im not sure
Step-by-step explanation:
Answer:
x intercept [a]=3
y intercept [b]=-5
we have
equation of a line is:
x/a+y/b=1
x/3+y/-5=1
(5x-3y)=15
5x-3y-15=0 is a required equation
