Answer: 90 rabbits</h2>
<em></em>
<h3><em>
Step-by-step explanation:</em></h3>
<em>you will need 10 for every 3 rabbits so if you count in tens and three's </em>
<em>3=10</em>
<em>6=20</em>
<em>9=30</em>
<em>and so on..</em>
<em>when you get to 27 you'll be at 90 </em>
<em>27=90 </em>
<em>hope u understand :></em>
For this question I'm just going to use / as a square root sign because I don't know how to do it on a computer. Anyways...
So you have /45
Now you have to find a factor that is also a perfect square which is 9 (because 9x5=45)
So you now have /9x5
Since 9 is a perfect square (/9=3)
You can re write it is 3/5 which is the answer
Answer: It will take Damon 6 weeks to save the money he needs to buy the snowboard
Step-by-step explanation:
First, let's see what the problem is giving us:
-The variable X will represent the number of weeks it will take Damon to save the money he needs.
- Damon has $40
- Damon is going to safe $20 weekly
- The snowboard costs $160
Therefor:
Our equation will be: $40 + $20X = $160
Step 1
We need to isolate the variable by subtracting in both sides of the equation 40 in order to maintain the equality.
40 - 40 + 20X = 160 - 40
This will let us with 20X = 120
Step 2
We have to isolate the variable again, but this time (because the variable is being multiplied by 20) we have to divide on both sides of the equation.
20X/20 = 120/20
Therefore: X=6
