You know that 7*7 is 49, and 6*6 is 36. Now you know it will be 6._. 6*7 is 42, so think of that as 6.5^2. You know that it will most likely be less than 6.8 since it is so close to being 7*7, which is 4 above your desired number. This leaves 6.6 to 6.8 as your estimate. Personally, I would go straight in the middle and choose 6.7.
I hope this helps!

Answer:
x = 5.5
Step-by-step explanation:
- 6-(2x-4)+x = 6-2x+4+x = 10-x
- 3(x-4) = 3x-12
- Based on the 1st and the 2nd steps, 10-x=3x-12 --> 10+12=3x+x --> 22 = 4x --> x =22/4 = 5.5
Answer: See below
Step-by-step explanation:
4 parts of the whole are shaded, and there are a total of 10 parts
So the fraction is: 4/10
Simplifying by dividing both the numerator and denominator by 2 would give <em>2/5</em>
Decimal: 4 divided by 10 is 0.4
Percentage: Decimal * 100 = 0.4 * 100 = 40%
