A rectangular tank is 100 cm long, 30 cm wide and 12 cm deep. What is the estimated capacity of the tank half full? Hint: 1000 c
Licemer1 [7]
To figure this out, you need to multiply all the dimensions together. 100x30=. 3,000cm and 3,000x12= 36,000 cubic centimeters. So now you can divide the 36,000 by 1000 to get the amount of liters the entire tank can hold. 36,000/1000= 36 liters. And because you want to know how much half of the tank is, you divide 36 by 2 and get 18 liters

ss7ja [257]

Answer:

y=-3x+4

Step-by-step explanation:

In function notation we have y in one side and the x (like free variable) and other numbers in the other side.

9x+3y=12

3y=12-9x

3y=-9x+12

y=(-9x+12)/3

y=-3x+4
