Answer:

f = 120

Step-by-step explanation:

The triangle is an equilateral triangle so each angle is 60 degrees

The interior angle plus f form a line which is 180 degrees

60 +f = 180

Subtract 60 from each side

60+f-60 =180-60

f = 120

2x+3y=9<br> 2x+y=7<br> simultaneous equation

Marat540 [252]

Answer:

x=3 and y=1

Step-by-step explanation:

subtract equation 2 from 1

then (2x+3y) -(2x+y) =9-7

2x-2x+3y-y =2

2y=2 therefore y=1

substitute y value in 2x+y=7

2x+1=7

2x=7-1

2x=6

x=3

How to find the rule for the nth term of a geometric sequence with changing common ratio?

ki77a [65]

Hmmm... a geometric sequence MUST have a fixed common ratio. If it is changing, then the sequence you are looking at might not be a geometric sequence at all. We'd need to see an example to be sure.
