Find the sum of the first 4 terms in the series.

175

Step-by-step explanation:

If the first term is 64 and the common ratio is 0.75, then

a(n) = 64*0.75^(n - 1).

Thus, a(2) = 64*(0.75)^(2-1) = 64*(0.75) = 48, and

a(3) = 36, and

a(4) = 27

The sum of the first 4 terms is 64 + 48 + 36 + 27 = 175

-1, -2, -3, -4, -6

step-by-step explanation:

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
