Answer:
maybe a. (b-c)=ab-ac (but im not sure)
You are looking at right angles in the problem. Right angles are 90 degrees.
So set up the problem to solve for X using:
90=4x+12
90-12=4x
78=4x
39/2 or 19.5 = x
Take all the non-zero digits and separate them from the zeros.
Then with zeros, how many are there?
Then multiply non-zero digits and zeros in powers.
3.482 * 10^6
Answer:
0.35 is one thousandth of 350
Step-by-step explanation:
Let
x ----> the number
we know that
The number multiplied by one thousandth must be equal to 0.35
so
The linear equation that represent this situation is

solve for x
Multiply both sides by 1,000

therefore
0.35 is one thousandth of 350
