Add the 3 ratio portions together: 1 + 4 + 7 = 12
Divide total length by 12:
84/12 = 7
Multiply each ratio portion by 7:
1 x 7 = 7
4 x 7 = 28
7 x 7 = 49
The longest piece is 49 cm
L: Large
s: Small
-2 (2L + 3s = 46)
4L + 8s = 105
-4L - 6s = -92
4L + 8s = 105
2s = 13
s = 6.5 kilograms
2L + 3 ( 6.5 ) = 46
2L + 19.5 = 46
2L = 26.5
L = 13.25 kilograms.
The cost of one sweatshirt is $19.
Step-by-step explanation:
Let,
Cost of one pair of jeans = x
Cost of one sweatshirt = y
According to given statement;
5x+2y=233 Eqn 1
3x+4y=193 Eqn 2
Multiplying Eqn 1 by 2
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 7
Putting x=39 in Eqn 2
Dividing both sides by 4
The cost of one sweatshirt is $19.

Answer:
one circle has a total angle of 360. Hence, 360-101= 3x+2+x-35
259=4x-33
292=4x
x=73 degrees
