The perimeter of a rectangle is 338, if the ratio of the length to the width is 8:5, find the length
STALIN [3.7K]
Let the length be 8x and the width = 5x, then
Perimeter = 2(length + width) = 2(8x + 5x) = 2(13x) = 26x
338 = 26x
x = 338/26 = 13

Therefore, length = 8x = 8 x 13 = 104

Solve by substitution<br> 3x-4y=-4<br> y=2x-4
dybincka [34]

Answer:

x=4 and y=4

Step-by-step explanation:

From first function we have:

3x - 4y =  - 4 \\ 4y = 3x  + 4

And from the second one:

y = 2x - 4 \\ 4y = 8x - 16

Substitute them:

4y = 3x + 4 \\ 4y = 8x - 16 \\  \\ 0 =  - 5x + 20 \\ x = 4 \\ y = 4
