Answer:
17) 3 18) 3
Step-by-step explanation:
2x + 5y = -8 . . . (1)
-133x - 4y = -8 . . . (2)
(1) * 4 => 8x + 20y = -32 . . . (3)
(2) * -5 => -665x + 20y = 32 . . . (4)
(3) - (4) => 673x = 0
x = 0
From (1), 2(0) + 5y = -8
5y = -8
y = -8/5
Answer:
w> 6
Step-by-step explanation:
Let w= the width
Let 4w = length
So then your equation becomes
2(w) + 2(4w) >60
Distribute
2w+8w > 60
Combine like terms
10w > 60
Divide by 10
w > 6
