The answer is 20. You use 20 markers for it all.
It is helpful to estimate quotients when the number is very big.
Real numbers, rational numbers, Integers, Whole numbers, and Natural numbers.
Answer:
The correct answer is <em>b = 36</em>
Step-by-step explanation:
In order to find out what b is, you must find out what 9/10 is.
9/10 is 0.9. This will later be used to check our answer.
Now, solve by using cross-multiplication
b * 10 = 9 * 40.
Then use the commutative property to reorder the terms
10b = 9 * 40
Now Multiply 9 * 40 = 360
10b = 360
Now divide both sides of the equation by 10
<em>b = 36</em>
<span>b – 2a – c
= 9 - 2(-3) - (-6)
= 9 + 6 + 6
= 21
