Answer:
Step-by-step explanation:
4/-2
Given:
The equation is:
![24+12=\_\_\times (8+4)](https://tex.z-dn.net/?f=24%2B12%3D%5C_%5C_%5Ctimes%20%288%2B4%29)
A model with 3 rows of 8 and 3 rows of 4.
To find:
The missing value in Ming's equation.
Solution:
We have,
...(i)
A model with 3 rows of 8 and 3 rows of 4. Using this information, we get
![24+12=3\times 8+3\times 4](https://tex.z-dn.net/?f=24%2B12%3D3%5Ctimes%208%2B3%5Ctimes%204)
Taking out the common factor 3, we get
...(ii)
On comparing (i) and (ii), we get the missing value is 3.
Therefore, the missing value in Ming's equation is 3.
This question is invalid. If Leslie drove 20 miles at 5 mph, it would take 4 hours, or 240 minutes.
<span> f (x)= 10-x³.
f(2) means the value of the function when x=2.
So, we need to substitute 2 instead of x.
f(2) = 10 - 2³ = 10-8 =2
f(2) = 2
