Answer:

Step-by-step explanation:

4/7 x + 70 cm^3 = 3/4 x          Subtract 4/7 x from both sides

3/4 x - 4/7 x = 70 cm^3          The lowest common denominator is 28

\frac{3*7*x}{4*7} - \frac{4*4x}{4*7} = 70 cc\\\frac{21*x}{28} - \frac{16*x}{28} = 70 cc\\\frac{5x}{28}= 70cc\\

5x = 70*28

5x = 1960                                Divide by 5

x = 1960/5

x = 392 cc

Answer:

  • 392 cm³

Step-by-step explanation:

<u>The difference of 3/4 and 4/7 of the volume is 70 cm:</u>

  • 3/4 - 4/7 = 7/7*3/4 - 4/4*4/7 = 21/28 - 16/28 = 5/28

5/28 of the volume is 70 cm³

<u>Divide both numbers by 5/28 to find the total volume of the glass:</u>

  • 70 : 5/28 = 70*28/5 = 392 cm³

Vlada [557]
If the goal is to sell at least $1500 worth of tickets then what you can do is add the 12.50+ 6.25 which well equal 18.75. Then you can divide 1500/18.75 which eqauls to 80 meaning at least 80 seats must be sold
