v = 684km/hr
Answer:
The answer is 7 plus ½ a number
Given: 6x + 3 = 27
First what we do is to subtract 3 from both sides:
6x + 3 – 3 = 27 – 3
6x = 24
Then we divide both sides by 3:
6x/3 = 24/3
<span>2x = 8</span>
if the cube's side equals 2 then it would be 2 x 2 x 2 = 8 or you could say 2 to the 3rd power or 2 cubed
Answer:
22
Step-by-step explanation:
m1 + m2 = 180
3x - 17 + 5x + 21 = 180
3x + 5x + 21 - 17 = 180
8x + 4 = 180
8x = 180 - 4
8x = 176
x = 176 / 8
x = 22
