The ratio of the robot's height to its arm length is 24 to 12 or 2 to 1. So if its height is 6 meters, then its arm length is 3 meters.
Answer:
least common denominator = 7y
Step-by-step explanation:
3/y = 21/7y
1/7y and 21/7y have a least common denominator of 7y.
Answer:
x<9
Step-by-step explanation:
<em>First, you do is add by 7 both sides of equation.</em>
<em>3x-7+7<20+7</em>
<em>Simplify.</em>
<em>20+7=27</em>
<em>3x<27</em>
<em>Then, divide by 3 both sides of equation.</em>
<em>3x/3<27/3</em>
<em>Simplify, to find the answer.</em>
<em>27/3=9</em>
<em>x<9 is the correct answer.</em>
-30x - 20: We can see that both numbers have a factor of -10, because 30 and 20 are multiples of 10 and -30x and -20 are both negative. So the factored form is -10(3x + 2).
12x - 28: The greatest common divisor of the two numbers is 4, so the factored form is 4(3x - 7).
-10x - 5: Like the first problem, the biggest factor is -5, so the factored form is -5(2x + 1).
Y = - 25.1
I hope this helps.
I hope you pass! :D
