2 is 10% of 20

solution:

what is 10% of 20?

y is 10% of 20

equation: y = p% * x

solving our equation for y

y = p% * x

y = 10% * 20

converting percent to decimal:

p = 10%/100 = 0.1

y = 0.1 * 20

y = 2

then

answer:

1

1 is 5% of 20

solution:

what is 5% of 20?

y is 5% of 20

equation: y = p% * x

solving our equation for y

y = p% * x

y = 5% * 20

converting percent to decimal:

p = 5%/100 = 0.05

y = 0.05 * 20

y = 1

then

answer:

3

3 is 15% of 20

solution:

what is 15% of 20?

y is 15% of 20

equation: y = p% * x

solving our equation for y

y = p% * x

y = 15% * 20

converting percent to decimal:

p = 15%/100 = 0.15

y = 0.15 * 20

y = 3

then

answer:

0.4

0.4 is 2% of 20

solution:

what is 2% of 20?

y is 2% of 20

equation: y = p% * x

solving our equation for y

y = p% * x

y = 2% * 20

converting percent to decimal:

p = 2%/100 = 0.02

y = 0.02 * 20

y = 0.4

then

answer:

2.5

2.5 is 5% of 50

solution:

what is 5% of 50?

y is 5% of 50

equation: y = p% * x

solving our equation for y

y = p% * x

y = 5% * 50

converting percent to decimal:

p = 5%/100 = 0.05

y = 0.05 * 50

y = 2.5

then

answer:

7.5

7.5 is 15% of 50

solution:

what is 15% of 50?

y is 15% of 50

equation: y = p% * x

solving our equation for y

y = p% * x

y = 15% * 50

converting percent to decimal:

p = 15%/100 = 0.15

y = 0.15 * 50

y = 7.5

then

answer:

1

1 is 2% of 50

solution:

what is 2% of 50?

y is 2% of 50

equation: y = p% * x

solving our equation for y

y = p% * x

y = 2% * 50

converting percent to decimal:

p = 2%/100 = 0.02

y = 0.02 * 50

y = 1

then

answer:

8.5

8.5 is 17% of 50

solution:

what is 17% of 50?

y is 17% of 50

equation: y = p% * x

solving our equation for y

y = p% * x

y = 17% * 50

converting percent to decimal:

p = 17%/100 = 0.17

y = 0.17 * 50

y = 8.5

then the last

answer:

19.5

19.5 is 39% of 50

solution:

what is 39% of 50?

y is 39% of 50

equation: y = p% * x

solving our equation for y

y = p% * x

y = 39% * 50

converting percent to decimal:

p = 39%/100 = 0.39

y = 0.39 * 50

y = 19.5

step-by-step explanation:

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'.
