Answer:
- given
- addition property of equality
- addition property of equality
- division property of equality
- symmetric property of equality
Step-by-step explanation:
In step 2, -3x was added to both sides in accordance with the addition property of equality.
The same property lets you add 18 to both sides, as in step 3.
The division property of equality lets you divide both sides of the equation by 5. (Or, the multiplication property lets you multiply by 1/5.)
Swapping sides of the equal sign is allowed by the symmetric property of equality.
Answer:
$117
Step-by-step explanation:
$90*10= $9
1 year is $9 interest, which is increase.
$9*3=$27
So than you add $27 and $90 and get $117
I can't see pictures, but to find the area of a triangle, you multiply the dimensions, as you would a rectangle, but divide the area by 2.
For example, the dimensions of a triangle are 4 and 6.
Multiply the two.
4x6=24.
But don't stop there. Divide 24 by 2.
24/2=12.
So the area of the example triangle is 12.

Answer:
Equation: 243+x=327
Answer to the equation: x=84
Step-by-step explanation:
First, subtract 243 from both sides of the equation, which would leave you with x=84, which is your answer.
I hope this helps! :)
Answer:
One.
Step-by-step explanation:
-4x + 6 = 6x - 2
-4x - 6x = -2 - 6
-10x = -8
There's only value of x which, when multiplied by -10 would produce -8.
That value is 0.8.
-10 * 0.8 = -8
No other value can produce the same result.
This means that there's only one solution.
