Answer:3(x-9) is expressed as 3x-27
Step-by-step explanation: 3(Xminus9)
3(X-9)
Use 3 to open the bracket by using 3 to multiply everything in the bracket.
Then you will get
3x-27
X+(-27)=110
x-27=110
x=137
hope that help you
Answer:
x + y
Step-by-step explanation:
An expression for the average of x,2x and 3y
average = (x+2x+3y)/3
= (3x+3y)/3
= 3(x+y)/3
= x + y
Step-by-step explanation:
- blue one ====> 3x+16 =9x+4 ( alternate angles)
>9x-3x=16-4
>6x=12
>x=2.
- white one ====> 10x-2=9x+5 (corresponding angle)
>10x-9x=5+2
>x=7.
- green one ====>8x+10=6x+30(vertically opposite angle)
>8x-6x=30-10
>2x=20
>x=10.
hope this helps you.
