P=x+38

add all individual sides together (is also the perimeter):
p=(x+3)+(x-5)+x+(x-2)+(x-4)+(x-1)+(x-1)
=7x-10

set both p equal:
x+38=7x-10
38=6x-10
48=6x
8=x

then insert x=8 in all the side/perimeter equations:
p=x+38=8+38=46

sides:
x=8
x-2=8-2=6
x-1=8-1=7
x-4=8-4=4
x-5=8-5=3
x+3=8+3=11

kakasveta [241]

Answer:

X= 5/12 + 1/24y

Y= -10 + 29x

Step-by-step explanation:

2(10- 24x)+ 2y 2(10- 24x)+ 2y

20 - 48x +2y 20 - 48x +2y

48x =20 +2y -2y = 20- 48x

/48 /48 /48 /-2 /-2 /-2

x= 5/12 + 1/24y y= -10 +29x

coldgirl [10]

Answer:

$6.75 and $4.50

Step-by-step explanation:

a) Jamal spent:

Isaiah spent:

3 (x - 2.25)

The equation is:

2x = 3(x - 2.25)

b) Solving the equation

2x = 3x - 6.75
3x - 2x = 6.75
x = 6.75

c) Jamal's items cost

$6.75 each

Isaiah's items cost

$6.75 - $2.25 = $4.50 each
