Answer:

x=1

Step-by-step explanation:

5(2x - 8) + 15 = -15

Distribute

10x -40 +15  = -15

Combine like terms

10x -25 = -15

Add 25 to each side

10x -25+25 = -15+25

10x =10

Divide by 10

10x/10 = 10/10

The length of the 2 black rods is equal to that of the 3 grey rods. The length of the white rod is equal to the total length of
Ivanshal [37]

Answer:

Length of grey rod is \frac{1}{4}th of the white rod.

Step-by-step explanation:

Let the length of each black rod = b units

Length of 2 black rods = 2b

Length of each grey rod will be = g units

Length of 3 grey rods = 3g

Since, length of 2 black rods = length of 3 grey rods

2b = 3g ----- (1)

Length white rod = Length of 2 black rods + Length of 3 grey rods

                         w = 2b + 3g

From the equation (1),

w = 2b + 2b

   = 4b

b = \frac{w}{4}

Therefore, length of grey rod is \frac{1}{4}th of the white rod .
