Question

4. Use the Distributive Property to Simplify: 3(5y + 9)

5. Use the Distributive Property to Simplify: 1/2(10y + 14)

6. Write the equation for: Nine less than twice a number increased by 15


7. Write the equation for: The quotient of a number and 3 is twice the number less than 1.

Answer 1

4. 3(5y+9)=3(5y)+3(9)

=15y+27

5. 1/2(10y+14)=1/2(10y)+1/2(14)

=5y+7

6. 2x-9+15

7. 3x=2x-1

Answer 2

4. 3*5y +3*9

15y+27

5. 1/2 *(10y + 14)

1/2 * 10y + 1/2* 14

5y +7

6. 2n -9+15 (i am not positive on the order of -9 and +15)

7. n/3 = 2n-1
