D = 20 , v = 19
20v + 12d - 6v
= 20 (19) + 12 (20) - 6 (19)
= 380 + 240 - 114
= 620 - 114
= 506
When d = 20 and v = 19
20v + 12d - 6v = 506

Answer:

506

Step-by-step explanation:

First what you would do is replace the v in 20v with 19 like so 20(19) and that would give you 380. Next you would replace the d in 12d with 12(20) and that would give you 240. Then replace the v in -6v with -6(19) and that would give you -114. Add them together and you get 506. The reason why -6x19= -114 is that a negitive times a positive equals a negitive. Or......

20v+12d-6v

20(19)+12(20)-6(19)

380+12(20)-6(19)

380+240-6(19)

380+240-114

<u>506</u>
