So first write out the expression:

take two 10's from the top to cancel with the two 10's on the bottom.
3.9/1.3 is 3.
The answer is 3*10^3
Hello, please consider the following.
We will multiply the numerator and denominator by

to get rid of the root in the denominator.
First of all, we cannot divide by 0, right? So, we need to make sure that the denominator is different from 0.

We need to take any x real number different from 8/3 then and simplify the expression.
Let's do it!

Thank you
Answer:
10a+3b÷c/3
Step-by-step explanation:
let the first number be a
second be b
third be c
10×a +3×b ÷c÷3
10a+3b÷c/3
=10a+3b÷c/3
Answer:
b= -164
Step-by-step explanation:
calculate the difference
7x(-75)-2b= -197
multiply the numbers
-525-2b= -197
move the constant to the right- hand side and change the sign
-2b= -197+525
add
-2b=328
divide
b= -164
