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:
The probability is 1/41664.
To calculate the probability, write a fraction. The numerator is the number of ways the outcome can occur. The denominator is the number of different outcomes.
Thus, 1 is the number of outcomes we want. 41664 is the total number of different combinations possible.
i dont think so because wouldnt be 18 and 18 or 16 and 16 like it just seems like it wouldnt be
Step-by-step explanation:
Answer:
Regular Polygon
Step-by-step explanation:
This is because:
<em>Convex</em> is when no angles can be over 180 degrees, meaning all points point outward
<em>Irregular</em> means that its interior angles and sides can be any measure
<em>Concave </em>is when at least one interior angle is over 180 degrees
Regular is all side measurements and angle measurements are the same
5 feet = 5*12 = 60 inches
the drawing is 10 in
the closet is 60 in
so the scale factor should be 10/60
or 1/6
