Hi there!

Here are the steps into solving this equation :

4dy + 12 = 7dy

subtract 12 from each side of the equation

4dy = 7dy - 12

subtract 7dy from each side of the equation

-3dy = -12

divide each side of the equation by -3

dy = 4

divide each side of the equation by "d"

y = $\frac{4}{d}$

There you go! I really hope this helped, if there's anything just let me know! :)

Answer:

7,13,31,85,247......

Step-by-step explanation:

$a_n =3^n + 4$

$\sf a_1=3^1 + 4 = 3 + 4 = 7\\\\a_2 = 3^2 + 4 = 9 + 4 = 13\\\\a_3 = 3^3 + 4 = 27 + 4 = 31\\\\a_4 = 3^4 + 4 = 81 + 4 = 85\\\\a_5 = 3^5 + 4 = 243 + 4 = 247$

You know that a number 8 less than 60 is the number 52. so, you could rewrite your answer from the previous part as, "what numbe

svetoff [14.1K]

I'm a little confused by your question.

You said 60-8 = 52 which is true.

Then, you asked 4x = 52 in an integer form
x = 52/4
x = 13. (Is that what you're asking?)

I'm not sure if this helps, but please comment if you need any help! Hope this helps though! :D
