To solve this problem just do the following,
x+9=-12
-9 -9
x=-21
Check
-21+9=-12 = True
Hope this helps!=)
To do this, we will need to find how much the elevator can hold in all. Multiply 10 by 250 to get 2500. Since it can also hold 10% more, multiply 2500 and 0.10 to find out how much 10% is. You get 250. Add 2500 and 250 to get how much the elevator can safely hold. It would be 2750.
To find out how much more weight can be added, first find out how much weight is on the elevator collectively. (books) 600+ (Jim) 180+ (Gavin) 330 + (Deb) 250 + (Susan) 120 = 1480. Subtract this from the amount the elevator can hold, and you get how much more weight can be added. 2750-1480= 1270.
The elevator can hold 1270 more ibs.
Answer:
5 hours
Step-by-step explanation:
1.5 (hours) / 3(cars) = 0.5 hours per car
0.5 x 10 = 5
Answer: 1 and -25
Step-by-step explanation:
1 x -25 = -25
1 + -25 = -24
