I think this is the answer for your question
<span>-6x = 3x-54
-6x - 3x = -54
-9x = -54
9x = 54
x = 54/9
x = 6</span>
4x-2
+2
so that leaves 4x
divide by four
x = 1
Answer:
∠1=160° and ∠2=20°
Step-by-step explanation:
Let ∠1 = x
∠2 = y
as these two angles are supplementary their sum is 180
that x+y=180 ----(A)
Also given that ∠1 is 20 degree less than nine times the size of ∠2.
Hence
x=9y-20
putting value of x in A and solving for y
9y-20+y=180
10y=180+20
10y=200
y=10
Putting this y in A
x+10=180
x=160
Step-by-step explanation:
Given,
perimeter = 94
length = 4y
breath = 5y + 2
perimeter = 2 ( l + b )
after inserting values we got,
2 ( l + b ) = 94
2 ( 4y + 5y + 2 ) = 94
2 ( 9y + 2 ) = 94
18y + 4 = 94
18y = 94 - 4 = 90
18y = 90
y = 90/18
y = 5
therefore,
length = 4y = 4×5 = 20
