- 2*(1+3)=8 => 2*4=8, 3*(4+5)=27=> 3*9=27. 4*(9+7)=64=> 4*16=64. 5*(16+9)=125 => 5*25= 125.
Either heads or tails so there is a 50/50 chance of both
9 = 1 + 8x - 8
Add 8 to both sides:
17 = 1 + 8x
Minus 1 on both sides:
16 = 8x
Divide both sides by 8
2 = x
Hope it helped :)
Answer:
The first one and the last one. A and D.
Step-by-step explanation:
A linear equation is and equation where the line is going up on a graph. In order for that to happen, y must always be bigger than x. The first and last chart all the way to the right is the only one that has that trait. :)
