Answer: x=5

Step-by-step explanation:

Simplify to 2x+ 3x -5 to 5x-5

5x- 5 = 20

Add 5 to both sides.

5x= 20+5

Simplify 20+5 to 25.

5x= 25

Divide both sides by 5.

x= 25/5

Simplify 25/5 to 5.

x=5

The sum of two segments are 75 cm, and one the segments are four times the other. Calculate the measurement of each segment

iVinArrow [24]

The length of one segment is 15 cm and other segment is 60 cm

Step-by-step explanation:

Let x be the length of one segment and y be the length of other segment

Then according to given statement

x+y=75 Eqn 1

And

one the segments are four times the other

x=4y Eqn 2

$Putting\ x=4y\ in\ equation\ 1$

$4y+y=75\\5y=75\\Dividing\ both\ sides\ by\ 5\\\frac{5y}{5}=\frac{75}{5}\\y=15\\Putting\ y=15\ in\ eqn\ 2\\x=4(15)\\x=60$

Hence,

The length of one segment is 15 cm and other segment is 60 cm
