allsm [11]

Answer:

Step-by-step explanation:

4x+2y = -24 -------------(i)

<u> -4x+y = 12 -</u>------------(ii)

add (i) &(ii) 3y = -12

y = -12/3

y = -4

Put y = (-4) in (i)

4x + 2*(-4) = -24

4x - 8 = -24

4x = -24 + 8

4x = -16

x = -16/4

x = -4

AveGali [126]

Answer:

Step-by-step explanation:

Perimeter of a triangle equals side 1 plus side 2 plus side 2

P = s1 + s2 + s3 side 1 = side 2 = x

x/side 3 = 5 / 3

x = (5/3) side 3

x (3/5) = side 3

perimeter = 65 slove for x

65 = x + x + 3x/5

325 = 5x + 5x + 3x

325 = 13X

25 = x equal side 1 and side 2

side 3 = 25(3/5) = 15
