Answer:
The parts are 27 cm and 64 cm long.
Step-by-step explanation:
Let the shorter part be x.
"The longer part is 10 cm more than twice as long as the shorter part."
shorter part: x
longer part: 2x + 10
total length: x + 2x + 10
total length: 91
x + 2x + 10 = 91
3x + 10 = 91
3x = 81
x = 27
2x + 10 = 2(27) + 10 = 54 + 10 = 64
Answer: The parts are 27 cm and 64 cm long.

Answer:
a
Step-by-step explanation:
Since x and y are directly proportional , so x = ky
6 = 42k
k = 6/42 = 1/7
12= (1/7)y
y = 84
Answer:
x = - 15
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180, that is
35 - 5 - 8x - 2x = 180 ( simplify left side )
30 - 10x = 180 ( subtract 30 from both sides )
- 10x = 150 ( divide both sides by - 10 )
x = - 15
