Step-by-step explanation:
Here is a helpful method I taught my students in my mini lesson...
For you to remember, 22= 4, and 32= 9. Hence the answer to the root of 8 lies between the numbers 2 and 3. However, since the square of 3 equals to 9 which is larger than 8, the root 8 value lies in between the number 2.8 and 2.9.
Can u show us how the location looks please?
Answer:
so x=3
Step-by-step explanation:
f(x) = 2
We want to find the x value when y =2
Going across where y = 2
Then go down to find the x value x=3 when y = 2
f(3) =2
so x=3
There would be 138 students in 6 classes because first you'd divide 207 from 9 and get 23 then you'd multiply 23 to 6 and get 138.
Answer:
The blank is 3
Step-by-step explanation:
1 - Give the blank a variable
x = our blank
2 - Write it out
![\frac{5}{7} + \frac{x}{6} = \frac{51}{42}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B7%7D%20%2B%20%5Cfrac%7Bx%7D%7B6%7D%20%3D%20%5Cfrac%7B51%7D%7B42%7D)
3 - Get the denominators equal
![\frac{5}{7}(\frac{6}{6}) +\frac{x}{6}(\frac{7}{7}) = \frac{51}{42} \\\frac{30}{42}+\frac{7x}{42} = \frac{51}{42}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B7%7D%28%5Cfrac%7B6%7D%7B6%7D%29%20%2B%5Cfrac%7Bx%7D%7B6%7D%28%5Cfrac%7B7%7D%7B7%7D%29%20%3D%20%5Cfrac%7B51%7D%7B42%7D%20%5C%5C%5Cfrac%7B30%7D%7B42%7D%2B%5Cfrac%7B7x%7D%7B42%7D%20%3D%20%5Cfrac%7B51%7D%7B42%7D)
4 - Simplify
![\frac{30+7x}{42} = \frac{51}{42} \\ \frac{30+7x}{42} = \frac{51}{42}](https://tex.z-dn.net/?f=%5Cfrac%7B30%2B7x%7D%7B42%7D%20%3D%20%5Cfrac%7B51%7D%7B42%7D%20%5C%5C%20%5Cfrac%7B30%2B7x%7D%7B42%7D%20%3D%20%5Cfrac%7B51%7D%7B42%7D)
5 - Solve for the numerators
30+7x = 51
-30 -30
7x = 21
x = 3
