the perimeter of a rectangle is 55 inches. the ratio of the length to width is 7:4. use proportions to find the area of the rect

Leni [432]

Answer:

Step-by-step explanation:

let : x the length and y the width .... ( x > y and x ; y reals numbers )

the perimeter is : 2(x+y)

2(x+y) = 55...(1)

x/y = 7/4 ...(2)

by (2) : x = (7/4)y

subsct in (1) : 2( (7/4)y +y ) =55

(7/2)y +2y =55

multiply by 2

7y +4y = 110

11y = 110

y = 10

x = (7/4)(10)

x = 35/2

Someone please help explain how to find x

dimaraw [331]

Answer:

x=27

Step-by-step explanation:

180-2x-40+180-3x+180-x-50+180-4x = 360

360-2x-40-3x+360-x-50-4x= 360

360-10x-90= 0

Which is the quotient if 3/5 and 1/10?

AlladinOne [14]

Answer:

Step-by-step explanation:

We have two fractions and are asked to find the answer if they both are divided.

3/5 and 1/10.

When we divide fractions, we need to follow KCF

KEEP - Keep the fractions

CHANGE - Change the division sign to a multiplication sign

FLIP - Flip the second fraction

Follow :

KEEP :

3/5 / 1/10

CHANGE :

3/5 * 1/10

FLIP :

3/5 * 10/1

Now we need to multiply, which is simple because it's multiplying across :

$\frac{3*10}{5*1}$

30/5

Simplify by dividing the numerator and denominator by 5 :

$\frac{30/5}{5/5} = \frac{6}{1}$

Divide the numerator by denominator :

$\frac{6}{1} = 6$

A line with a slope of 3/4 passes through (-4,-2). Write the equation of the line in standard form.

Gnesinka [82]

Standard form is Ax + By = C

Your equation is y = 3/4 x + 1

3/4 x + 1 y = 1
