Round 4.139 to the nearest hundredth.

4.14

Step-by-step explanation:

We are given that

4.139

We have to round 4.139  to the nearest hundredth.

Place of 4 in 4.139=unit

Place of 1 in 4.139=Tenth

Place of 3 in 4.139=Hundredth

Place of 9 in 4.139=Thousandth

Thousandth place is 9 which is greater than 5. Therefore, 1 will be added to hundredth place and all digits on left side of hundredth place remain same and digit on right side of hundredth place will be replace by 0.

Hence, the number =4.14 (nearest to hundredth)

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'.
