4. D 9

5. A 21x = 892.50

6. B 5 + y = 17

7. A 8

Step-by-step explanation:

4.

[tex]3k + 7 = 34[/tex]

[tex]3k = 34 - 7 = 27[/tex]

[tex]k = \frac{27}{3} = \boxed 9[/tex]

7. Let x = the number, therefore:

[tex]3x + 11 = 35[/tex]

[tex]3x = 35 - 11 = 24[/tex]

[tex]x = \frac{24}{3} = \boxed 8[/tex]

Hope it helps.
