Answer 1

Answer:

3.  -7/5  x  ( 4/5 + 9/15)

   -7/5( 4/5 )   +   -7/5 (9/15)

   -28/25 + -21/25

    - 49/25

4.  x + y = 17

   +x - y = 1

2x = 18

x = 9

9 - y = 1

y = 9 - 1

y = 8

the two digit number is 10x+y

10(9) + 8

98

5. volume of a cube = a^3

  given volume = 10.648

    a^3 = 10.648

     a    = $\sqrt[3]{10.648}$

     a  = 2.2 ( approximately)
