Hello!
The Correct Answer to this is that <span>7 divided by 20 or 7/20 equals:
"7/20 = 0.35"
</span>Explanation:
Since you are trying to find equivalent values for 7/20, you can make two proportions and set them equal to each other. The following states that "7 out of 20 is equal to some amount out of 100."
<span><span>7/20</span>=<span>x/100</span></span>
Solve by cross multiplying:
<span>20x=700</span>
Divide both sides by 20 to isolate x:
<span>x=35</span><span> Therefore, </span><span><span>7/20</span>=<span>35/100</span></span><span>. This is the same as saying 35%, since by definition "per" means out of, and "cent" means hundred. To make it into a decimal just move the decimal place two digits to the left, such that 35.00 becomes 0.35, and 100.00 becomes 1. Then it is simply </span><span>0.35/1</span><span>, or 0.35</span>

Hope this Helps! Have A Wonderful Day! :)</span>
Answer:
you get the measure of angle XYZ by adding the measures of angles XY? and ZY?
70 +35 = 105 degrees is the measure of angle XYZ
You just have to think what is 40% of 100 which is 40 then multiply 40 2 times to find out the answer four 40% of 200 when you do 40x2 it =80 so the answer is 80
Answer:
![log_{7} \frac{7}{x^{2} }](https://tex.z-dn.net/?f=log_%7B7%7D%20%5Cfrac%7B7%7D%7Bx%5E%7B2%7D%20%7D)
Step-by-step explanation:
We need to write
as a single logarithm.
We know that
![log_{7}7 = 1](https://tex.z-dn.net/?f=log_%7B7%7D7%20%3D%201)
Therefore we have:
![log_{7}7 - 2log_{7}x](https://tex.z-dn.net/?f=log_%7B7%7D7%20-%202log_%7B7%7Dx)
→ ![log_{7}7 - log_{7}x^{2}](https://tex.z-dn.net/?f=log_%7B7%7D7%20-%20log_%7B7%7Dx%5E%7B2%7D)
→ ![log_{7} \frac{7}{x^{2} }](https://tex.z-dn.net/?f=log_%7B7%7D%20%5Cfrac%7B7%7D%7Bx%5E%7B2%7D%20%7D)
The solution is: ![log_{7} \frac{7}{x^{2} }](https://tex.z-dn.net/?f=log_%7B7%7D%20%5Cfrac%7B7%7D%7Bx%5E%7B2%7D%20%7D)
Answer: x=3.4
Step-by-step explanation:
0.5x + 4.2 = 5.9 \\ 0.5x = 5.9 - 4.2 \\ 0.5x = 1.7 \\ x = 1.7 \div 0.5 \\
