Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
x + 6 = 2(x + 3) - x
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Addition Property of Equality] Add <em>x</em> on both sides: 2x + 6 = 2(x + 3)
- [Distributive Property] Distribute 2: 2x + 6 = 2x + 6
Here we see that both sides are identical.
∴ our solution is all real numbers.
Answer:
Improper Fraction : $22/5
Decimal : $4.4
Mixed: $4 2/5 ...
Step-by-step explanation:
Sherman Has 3 cats and 2 dogs
Sherman has $22 to spend on pet toys.
To find the answer divide the overall amount that Sherman has to spend overall which is $22, Now divide it by the amount of pets that he has, 3+2=5
We can write it as:
Improper Fraction : $22/5
Decimal : $4.4
Mixed: $4 2/5 ....
The statement is false, as the system can have no solutions or infinite solutions.
<h3>
Is the statement true or false?</h3>
The statement says that a system of linear equations with 3 variables and 3 equations has one solution.
If the variables are x, y, and z, then the system can be written as:
Now, the statement is clearly false. Suppose that we have:
Then we have 3 parallel equations. Parallel equations never do intercept, then this system has no solutions.
Then there are systems of 3 variables with 3 equations where there are no solutions, so the statement is false.

Answer:
A. 2 acute and 1 right angle.
For the first number you can choose from 8, for the second number only 7, for the third number only 6. So the number of combinations is 8x7x6=336
