So my teacher sucks at explaining this so I need someone's help to solve it.
galben [10]
So x is a variable which is just <span>character representing a number. We want to find x. To do this we want to get X by itself on one side of the equation. In this case/ we just need to divide both side by -4. Whatever you do to one side, you must do to the other. This gives us  X = -12. To check yourself just plug your answer back into the equation to see if its right. -4(-12) = 48. You have successfully solved for X.</span>

the first term in a geometric series is 64 and the common ratio is 0.75. Find the sum of the first 4 terms in a series.
Rufina [12.5K]

hi

u0 = 64       with  u(n+1) = un *0.75  

u3 =  64 *0.75^3   = 27

sum is :      64 *  ( 0.75^4 -1)  / 0.75-1  = 175

manual proof :    64 + 48+36+27 = 175
