Answer:
whichever of these formats you need its the same answer (16/6) or 2.66666 or (2 and 2/3rds)
Step-by-step explanation:
replace smaller variable with x for example
(x) + (5x-1) = 17
6x-1=17
6x=16
x=(16/6 or 2.666666 or 2and2/3)

Step-by-step explanation:
note that 3.28 = 2 × 1.64
This could be a geometric sequence with common ratio r = 2
To obtain the next term multiply the previous term by 2
3.28 × 2 = 6.56
6.56 × 2 = 13.12
1.64, 3.28, 6.56, 13.56 ← first 4 terms in sequence

Answer:
7 cm, 4.4 cm
Step-by-step explanation:
The side lengths can be found from the law of cosines. Each triangle has legs 3 cm and 5 cm. The angle between these will be 60° or 120°. Then the two sides of the parallelogram are ...
s = √(a² +b² -2ab·cos(C))
s = √(3² +5² -2·3·5·(±1/2)) = √(34 ±15) = {√49, √19}
The two side lengths are 7 cm and about 4.4 cm.
