Answer:

1. x+4x

2. 5x

3. 6\frac{7}{x}

4. 4x-2x+15

5. (6+x)^2

Step-by-step explanation:

To write expressions remember these key words:

  • a number is a variable like x
  • sum is +
  • difference and subtracted is -
  • quotient is ÷
  • product is ×
  • reciprocal means flip like \frac{1}{9}---> \frac{9}{1}
  • square is an exponent of 2 like x^2

1. x+4x

2. 5x

3. 6\frac{7}{x}

Remember a quotient would be \frac{x}{7}but the reciprocal is \frac{7}{x}.

4. 4x-2x+15

5. (6+x)^2

Casey dug a cubical hole to bury a memory box as a time capsule. The volume of the dirt he removed is 729 cubic inches. How many
Arlecino [84]

Answer:

The hole is 9 inches deep

Step-by-step explanation:

Volume of a cubicle hole = a^3

Where a= side edge of the cube

Volume of dirt removed = 729 cubic inches

How many inches deep is the hole

Volume of a cubicle hole = a^3

729 = a^3

Find the cube root of both sides

3√729 = 3√ a^3

9 = a

a= 9 inches

The hole is 9 inches deep

Check:

9^3

=9 *9*9

= 729

760 total students....4 out of 7 graduated...3 out of 7 didn't

and 3/7(760) = 2280/7 = 325.7...and approx. 326 won't graduate
