1. Line 3 is the first error. In order to get rid of the 25, you add it to both sides, not subtract. So, your answer is B.
2. Line 1 because it says in the question "4
less than a number" and the equation adds 4, instead of subtracting. Your answer is A.
3. Line 4. To get rid of the 6 in front of 6x, you have to divide by it, but instead they multiply. So, your answer is C.
4. To solve this, you will use the distributive property first:
Turns into:
Get rid of the 12:
Divide by 4:
Your answer is B.
5. You have to set it up:
Just solve for x:
Multiply both sides by 3 to isolate x:
Your answer is B.

Answer: There are 27 votes for Florida.
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The number of votes of North Carolina (15) must be equal to the number of votes of Florida (x) minus 12.
Mathematically speaking:
15 = x -12
Solving for x:
15+12 = x
27 = x
There are 27 votes for Florida.
Feel free to ask for more if needed or if you did not understand something.

Answer:
c=8
Step-by-step explanation:
-3(2c+5)=33
-6c-15=33
-6c=33+15
-6c=48
c=48/6
c=8
Answer:
The value at the end of year 2 is $4400.
Step-by-step explanation:
The best approach here is to determine the expression for the line depreciation and then calculate the depreciation value at x = 2 years.
A line is given by
where m is the slope and b the bias (aka y-intercept). You can determine both directly from what is given. The slope is change in y divided by change in x. We know that over 5 years the car loses (500-7000)=-6500 in value. So, the slope is m=-6500/5 (note the negative sign). At time 0, the y-intercept is 7000, since that is the initial value (at year 0). So our line function is fully identified:
and gives you the value of the car in any given year. To answer the question, we now plug in 2 as value of x:
