in the equation as we can say x= 2y-10.
so, substitute x=2y-10 everywhere then the x in 1240 gets cancelled with 2y-10 then solve the remaining you will get 4y-20+3y=1240
7y=1260
y=1260/7
y=180
then substitute the value of y everywhere
2x+3y=1240
2x+3(180)=1240
2x=1240-540
2x=700
x=350
DONE.
The answer is 66.75
I would suggest multiplying 2 in (2x+1) by 2 5/8 first, then multipling 4 by 2 5/8. This will garner you 10 and 5.25. Distribute the 9 into the (). You'll then get 10.5+47.25+9
Add and you will get 66.75
Answer:
Step-by-step explanation:
Given the inequality
|x|> 1
The modulus of x shows that x can be both positive and negative value.
If x is positive:
x>1
1<x
If x is negative:
-x>1
Multiplying both sides of the inequality by minus will change the inequality sign
x < -1
Combining both inequalities:
1<x<-1

The answer is
a−120
because -5*-3=15 because negative and a negative = a positive
Now 15*-8 =-120 that's because a negative and a positive
Answer:
Step-by-step explanation:
Given a basket, the probability of a ball to end there is (because there are m baskets).
Then, the probability of a ball to end in other basket is .
Finally, the probability of the basket to remain empty after n throws is
This last is because, given n independets events with probability p, the probability for all of them to happen is . In this case
