1. A tank is 3/5 full of water. After 330 litres of water is drawn out, it becomes 2/7 full. Find the capacity of the tank in li
Andreas93 [3]

Answer:

1050

Step-by-step explanation:

Let x = full capacity

\frac{3}{5} x=\frac{2}{7} x+330

Move the variable to the left side by subtracting both sides by \frac{2}{7} x

\frac{3}{5} x-\frac{2}{7}x=\frac{2}{7} x+330 -\frac{2}{7}x

\frac{3}{5} x-\frac{2}{7} x=330

Combine the like terms (don't forget about common denominator)

\frac{21}{35} x-\frac{10}{35} x=330

\frac{11}{35} x=330

Multiply both sides by \frac{35}{11} to isolate the x

(\frac{35}{11})\frac{11}{35} x=330(\frac{35}{11})

x = 1050

O a Olivia went to a dance party. She paid $12 as an entry fee. Once inside the dance party, she paid $2 per snack. She started
Oduvanchick [21]

Answer: 2x + 12 = 30

12 is the initial fee, then x is the unknown variable. Since each snack costs 2 dollars, and we don't know how many she had, we can use the equation:

2x +                   12 =               30

|                           |                     |

snack          initial                total

fee                fee                 $ spent
