Becouse k and n are 'neighbours' so their sum are 180
so k=180-42=138
-12 + 3x + 2 = 5x - 10 - 8x
-10 + 3x = -3x -10
-10 + 6x = -10
6x = 0
x = 0
Answer:
1, i can't see the pic so i can't answer the Question
Step-by-step explanation:
A unit fraction means that the fraction has 1 in the numerator. To make 3/8 a unit fraction, you have to make it 1/8 by dividing by 3.
So now you have 3 x 3 x 1/8. You can multiply the 3 and 3.
You are left with 9 x 1/8.
Answer:
y=35
Step-by-step explanation:
10(y+7)=12y
10y+70=12y
70=12y-10y
70=2y
70/2=y
35=y
therefore, y=35
