Solve the equation 1/30 + 1/45 = 1/x
where x is the required time
multiply thru by 90x:-
3x + 2x = 90
x = 90 / 5 = 18
answer 18 minutes
Answer:
Each steamer costs $2.5 and each party hat costs $1.5
Step-by-step explanation:
Let the cost of 1 steamer =x
Let the cost of 1 party hat =y
Three rolls of streamers and 15 party hats cost $30
Two rolls of streamers and four party hats for $11.
We solve the two equations simultaneously.
Multiply equation 1 by 2 and equation 2 by 3
6x+30y=60
6x+12y=33
Suntract
18y=27
y=1.5
From 6x+30y=60
6x+30(1.5)=60
6x+45=60
6x=60-45=15
x=2.5
Since x=2.5 and y=1.5
Each steamer costs $2.5 and each party hat costs $1.5
Answer:
1: 6 ^ 3
2: Neither
3: 6 ^ 3
4: 6 ^ -3
Step-by-step explanation:
First off, GOOD LUCK IXL IS AHDIOFJDSFS
(Second, I hope I am correct and gotchu, I think I am though, have a nice day!)
<u>Third:</u>
1: 6 ^ 3 If you mutiple it out then the negatives will cancel each other out
2: Right off the bat we can tell it is neither because a 3 times a 3 won't equal a 3.
3: 6 ^ 3 (flip fraction and change sign)
4: 6 ^ -3 (flip fraction and change sign)
