Answer:
23y
Step-by-step explanation:
this my answer hope it's help
make me brainless pls
X + y = 10
y = x + 2
so sub in x + 2 for y back into the first equation
x + y = 10
x + x + 2 = 10
2x + 2 = 10
2x = 10 - 2
2x = 8
x = 8/2
x = 4
y = x + 2
y = 4 + 2
y = 6
solution is : (4,6)
Answer:
Width = 160
Length = 110
Step-by-step explanation:
Perimeter is the sum of all the sides
They tell you that the length is 50 m shorter than the width
so L = W - 50
W = W
540 = W + W + W-50 + W-50
540 = 2W + 2(W-50)
540 = 2W + 2W - 100
540 = 4W - 100
640 = 4W
W = 160
L = 160 - 50
L = 110
