Answer:
x=3 and y=-1
Step-by-step explanation:
2x-3y=9
3x+5y=4
Change equations in order to make a variable cancel out. In this case, multiply the top by -3 and the bottom by 2
-6x+9y=-27
6x+10y=8
Add the equations
19y=-19
y=-1
Plug in y=-1 into any equation
2x-3(-1)=9
2x+3=9
2x=6
x=3
Answer:
yes because im depressed
Step-by-step explanation:
The answer to the problem is x - 1
divide 1006 by 12
1006 / 12 = 83.833
so 83 full trucks
83 *12 = 996
1006-996 = 10 cars will be on the last truck
Answer:
C, A and B
Step-by-step explanation:
Tank A holds 40 Liters and 5 fish.
- Volume per fish of Tank A
Tank B holds 100 Liters and 12 fish.
- Volume per fish of Tank B
Tank C holds 180 Liters and 23 fish.
- Volume per fish of Tank C
Therefore, the volume per fish from least to greatest is:
7.83, 8 and 8.33
These correspond to the tanks: C, A and B respectively.
