3) What percent of 55 is 34?

4) 41% of 78 is what?

5) 28% of 63 is what?

6) 58% of what is 63.4?

See below.

Step-by-step explanation:

1) What percent of 29 is 3?

3/29 * 100% = 10.3

2) What percent of 33.5 is 21?

21/33.5 * 100% = 62.7%

3) What percent of 55 is 34?

34/55 * 100% = 61.8%

4) 41% of 78 is what?

41% * 78 = 0.41 * 78 = 32.0

5) 28% of 63 is what?

28% * 63 = 0.28 * 63 = 17.6

6) 58% of what is 63.4?

58% * x = 63.4

0.58x = 63.4

x = 63.4/0.58 = 109.3

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'.
