Perimeter=2L+2W
L=W+5, substitute in place of 2L
90=2(W+5)+2W
90=2W+10+2W
90-10=4W
80=4W
80/4=W
W=20, if width is 20 than the length is 20+5=25 cm
Answer:
(-1, 4) , (0, 6), (1, 9), (2, 13.5)
Step-by-step explanation:
Hey there!
Given equation :
... 0.2 ( x + 50 ) - 6 = 0.4 ( 3x + 20 )
Using the distributive property.
... 0.2x + 10 - 6 = 1.2x + 8
... 0.2x + 4 = 1.2x + 8
Subtract 4 on both sides.
... 0.2x = 1.2x + 4
Subtract 1.2x on both sides.
... - x = 4
... x = -4
Hence, the answer is -4.
Hope it helps!!
