Question

roma has 2 blue sticks and 5 red sticks . the length of 1 blue stick is 3 times that of the red stick . the total length of the 7 sticks is 127 cm. find the length of 1 blue stick.​

Answer 1

Answer:

x = 34.5cm, y = 11.5cm

Step-by-step explanation:

Length of blue stick = 3times Length of Red Stick

Let x be the length of blue stick and y be the length of red stick

then x = 3y

Then ATQ

2x + 5y = 127

2(3y) +5y = 127

6y + 5y = 127

11y = 127

y = 127/11

y = 11.5cm

x = 3y

x = 11.5 X 3

x = 34.5cm
