The ratio of the length of the rectangular field to its width 5: 2. the length of the field is 30yd. find the perimeter and area

Perimeter= 84

Area= 360

Step-by-step explanation:

We know that this field has portions split up by 7. The length is 5/7 of that, and the width is 2/7.

We know that the length is 30yd. 30/42 is the equivalent of 5/7. That means that 12/42 is the equivalent of 2/7.

Thus, the width of the field is equal to 12.

To find the perimeter we will add all sides. 30 + 30 + 12 + 12 = 84

We will multiply them to find area. 30 * 12 = 360

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'.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
