Answer:
The equation to solve the problem is
306 = 249 + x
x = 306 - 249
Hence:
57 students went outside
Step-by-step explanation:
Let the number of students outside be represented by x
Hence:
Number of students in the cafeteria = Number of students inside - Number of students who went outside
We are told:
There were 306 students in the cafeteria. After some went outside, there were 249 students left in the cafeteria.
The equation to solve the problem is given as:
306 = 249 + x
x = 306 - 249
Hence:
x = 57
57 students went outside
Given:
Seeds planted = rows
Crows ate = rows
To find:
The remaining rows of seeds.
Solution:
According to the question,
Remaining rows of seeds = Seeds planted - Crows ate
Taking LCM, we get
Therefore, rows of seeds are left.
Given:

Step-by-step explanation:
Answer
12 root 3
Answer is irrational (because it) can’t (and it’s decimal expansion) doesn’t (terminate or repeat)
You can see this by simply plugging the surd into the calculator
Step-by-step explanation
Sum of 2 root 3 and 5 root 12
Root 12 can be written as:
root 4 • root 3
root 4 = 2
= 2 • root 3
Multiply with the 5 from q
= 10 • root 3
Now the terms can be added
2 • root 3 + 10 • root 3 =
12 • root 3
