Answer:
107.500
Step-by-step explanation:
5.450.000-75.000=5.375.000
5.375.000:12 1/2=5.375.000:25/2=5.375.000*2/25=430.000
430.000:4=107.500
+ and - ,
* and :
are inverse operations
Where it is an operation and the result is a number , we have to do the inverse operation for finding the initial number.
verifying :
107.500*4*12 1/2+75.000=5.450.000
A fact family is made up of three numbers. Just as in any family the members, or numbers, are related and there are always at least four math facts to be made with them. Take, for example, these members of a fact family: 6, 4, and 10.
In the family 6, 4, and 10 they are related because you can add two of the numbers to get the last number.
6 + 4 = 10
You can also switch the first two numbers, using the commutative property of addition, and still get the same answer.
4 + 6 = 10
Just find how they can relate! Hope it helps!

Answer:
-12
Step-by-step explanation:
Step 1: Add 18 to both sides.
−2x−18+18=6+18
−2x=24
Step 2: Divide both sides by -2.
−2x
−2
=
24

General Formulas and Concepts:
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
- Solving systems of equations using graphing
Step-by-step explanation:
To find the solution set of a systems of equations, the point where the 2 lines intersect would show the solution for the systems.
According to the graph given, both lines intersect each other at x = -1.
Therefore, our answer is B.
