Isolate the variable by subtracting the 10 from Both sides...
You are then left with
2x=10
Then divide both sides by 2 (to isolate the variable)
Therefore
X=5
Divide by 10 to find how many tens he needs.
1200/10 = 120
Answer: He needs 120 tens
Reason 1. AB is congruent to DC - given
Reason 2. AB is parallel to DC - given
Reason 3. angle BAC is congruent to angle DCA - alternate interior angles are congruent
Reason 4. AC is congruent to AC - reflexive property of congruence
Reason 5. triangle ABC is congruent to triangle CDA - Side Angle Side
AC is congruent to AC - reflexive property of congruence
We have to divide 9/10 by 3/12.
if we divide by a fraction, we can instead multiply by it's inverse:

so now we count:

so we can cut exactly 3 pieces!
Answer:
Yes, 9 is the answer.
Step-by-step explanation:
This is a one step equation so you only have to preform one operation to solve. You do the inverse operation of what the equation is doing. In this case you are multiplying, which means you will divide to solve.
63/7 = 9
