Answer:
A - 2x + 4 + 50 = 10x - 2
Step-by-step explanation:
1.) It is the only equation that makes mathematical sense
2.) The sum of angles ABD and DBC equal angle ABC, and ABC = 10x -2
Note:
x=7 if it is important later on
Answer:
C. C is the only one that is rational out of all of them. The rest are irrational
Step-by-step explanation:
A ratio is a relation between two numbers.
*A ratio determines how many times 20 contains/values 8.
<u>A ratio representing the width to the length is: </u>
8:20.
8 represents the width, 20 represents the length.
To simplify a ratio, you must divide each side by the same number.
<u>S</u><u>i</u><u>mplified </u><u>ratios</u><u> </u><u>are</u><u>:</u>
4:10 (Divide by 2)
2:5 (Divide by 4)
1:2.5 (Divide by 8)
The ratio is detailing that the length is 2.5 times larger than the width.
<u>Your answers are;</u>
8:20
4:10
2:5
1:2.5
Answer:
Step-by-step explanation:
First, subtract 7 from each side.
Now, add in a blank on each side so you can write in your new term that will complete the square. We'll call that term 's' for now.
The next step is to take half of the b term, and then square that. In this case, half of '' is . If we square that we get . So that is the term we will put in for .
Simplify:
If you look at the right side of the equation, we can factor. That's because we <u>completed the square</u>. We can use the 'guess and check' method to factor. Remember, this is where we use 2 sets of parentheses and fill in the blanks.
If we were to FOIL the right side we would end up with .
Since we have 2 '(x-1)' terms next to each other, we can simplify to:
Now, all we need to do is add 6 to both sides and we have the vertex form.
I hope this helps!
If large eggs are 60 grams, and you have 12, multiply 60 by 12 and you get the final answer. So 12 large eggs has a mass of 720 grams. Hope that helps!
