The diameter of a strand of rope is 1.2 ×10^-3 inch. The diameter of a strand of floss is 2.0 ×10^-4 inch. How much longer is the diameter of the strand of rope than the diameter of the strand of floss?
A. 2.0 ×10^-7 inch
B. 1.0 ×10^-7 inch
C. 2.0 ×10^-3 inch
D. 1.0 ×10^-3 inch

D. 1.0 x 10^-3

Step-by-step explanation:

1.2 ×10^-3 = .0012

2.0 ×10^-4 = .0002

.0012

.0002

.0010 = 1.0 x 10^-3

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.

1; 35 is the ratio
