You can do this by finding a number close to it, and then finding out how to do it.
For example with 63(square root sign), find out what is close to it.
7x7=49 while 8x8=64
Because of this, we now know that it is between 7 and 8 but is also really close to 8.
Our number could be 7.9

ANSWER
For Jamal statement to be true,
EXPLANATION
The given statement is:
ax + b = a(x + c)
We expand the left hand side to obtain,
ax + b = ax + ac
Subtract ax from from both sides of the equation.
b=ac
We know that, a≠0 , so we can divide through by 'a'.
The answer: In Classroom 1, there are 5 students while in Classroom 2, there are 10 students.
Explanation:
x + 2x = 3x
3x = 15
x = 5, Classroom 1 = 5, Classroom 2 = 5 x 2 = 10
I hope that this helps! :)
Answer:
Step-by-step explanation:
8x - 20.....factor a 4 out
4(2x - 5) <=== this one is correct...not 100% sure who wrote it
8x - 20...factor out a 2
2(4x - 10) <==== this is correct
8x - 20....factor out a -2
-2(-4x + 10) <==== this is correct
8x - 20....factor out a -4
-4(-2x + 5).....nobody did this one......but somebody tried....that person didn't factor correctly
