33=3×11

this the geometric sequence. ( comon : 3)

the nth term is : An = A1 × r^n when : r = 3 and A1 =11

if n = 19 A19 = 11×3^19

Need help little confuse

lara31 [8.8K]

3(2-y) + y = 4.50
6 - 3y + y = 4.50
- 2y = -1.5
y = 0.75

3x + y = 4.50
3x + 0.75 = 4.50
3x = 3.75
x = 1.25

answer
x = 1.25 and y = 0.75
